2,000 Guineas Preview (stamina aptitude)

Steve Miller                              2,000 Guineas – Dosage Special

Kingman has right blend of speed and stamina for the 2,000 Guineas – but Australia (and Kingston Hill) should be backed for the Derby ahead of Saturday’s race on the expectation of a decent showing at a trip likely to be short of his best

Index flags up contrast in race suitability between 

Kingman and Australia


AS A NEW classic generation emerges we barely have time to reflect that while the players change the systems for sorting them out remain essentially the same. The 2,000 Guineas poses the usual conundrum of brimming potential set against typically scant form. Where the form is inconclusive we look to the Dosage system to identify those with the best blend of speed and stamina to satisfy the demands of the race.

The table shows the 17 left in at the confirmation stage. In crude terms those with the most stamina potential appear at the top and those with the least at the bottom, ranked in order of the Dosage Index (DI). Those with the best chances must not only make the grade in terms of ability, but will also need an optimum blend of speed and stamina in relation to the others in the race.

Key to Profile: Left to right columns, ranging from speed to stamina: Brilliant, Intermediate, Classic, Solid, Professional. DI = Dosage index; CD = Centre of distribution.
The Centre of Distribution (CD) scale complements the DI. The CD covers the range from +2 to -2, where +2 corresponds to the Brilliant aptitudinal group in the Dosage profile (DP), +1 corresponds to Intermediate, 0 corresponds to Classic, -1 corresponds to Solid, and -2 corresponds to Professional. A low (close to zero) or negative CD indicates enhanced stamina potential.


The Dosage is of decisive help to us this year as it separates the first two in the betting (at the time of writing) – Kingman who is extremely well suited to the distance requirement and Australia who will thrive at middle distances. Both are highly talented and both can be expected to run well in this, but only one is an ideal fit to the demands of this race.

Blue blood

The highly regarded Aidan O’Brien-trained Australia is a son of Galileo out of the Cape Cross mare Ouija Board. Connections will be willing this bluest of blue bloods to carry all before him and his trainer has designated him the latest of an ever-extending sequence of best things that the yard has had. The colt certainly looks decent, but wishing something so isn’t the same as it being so. He won a Group 3 at Leopardstown in taking style last term after a couple of satisfactory maiden performances. Australia has a fine Dosage profile for the Derby, with a DI of exactly 1 and a CD close to zero (0.19), but it may prove worthwhile looking for something lower down the table in this exacting classic, in which the best suited to the race invariably comes out best.

Australia’s stablemate, the Dewhurst winner War Command showed solid form in his five appearances last term. The son of War Front is on a DI of 1.61, which is much more in line with that of a typical Guineas winner than his better-fancied stablemate Australia, who looks to have more stamina than is usually associated with a winner of this race (Camelot and Frankel aside, in recent years). The useful Giovanni Boldini and Oklahoma City make up the Ballydoyle contingent of four.

The John Gosden-trained Kingman was mightily impressive on his return to action taking the Greenham Stakes convincingly from the talented Night Of Thunder with the rest strung out. The son of Invincible Spirit is clearly very smart and appears to have just the right blend of speed and stamina, on a DI of 2.08. As I’m a big fan of Hannon’s Night Of Thunder, I have to think that Kingman will take a world of beating in this.

Hannon’s hand

The impressive Listed winner Night Of Thunder looked to be going places after smart victories at Goodwood and Doncaster last term and although well beaten behind Kingman on his reappearance looks to be a colt brimming with potential. By Dubawi out of a Galileo mare, the mile will not present a problem and he may well improve again for middle distances. He remains in the mix here, but according to connections could switch to the French 2,000 Guineas.
Night Of Thunder’s stablemate Toormore was officially last season’s top-rated two-year-old when he was unbeaten in three outings, culminating in the Group 1 National Stakes at the Curragh. The son of Arakan ran out a fine winner of the Craven giving a 3lb penalty to runner-up The Grey Gatsby. He looks a very credible contender over the Rowley mile and makes our shortlist for this. Shifting Power, by Compton Place, is another smart unbeaten colt completing the Hannon hand of three. He looks like he will do well at 8 furlongs, although the Dosage has him on a high index suggesting speed over stamina.

The Roger Varian-trained Racing Post Trophy winner Kingston Hill is by Mastercraftsman out of a Rainbow Quest mare and will be suited to performing beyond this trip. He would also be suited by any give in the ground and rain is due (Newmarket may also water).

With Saeed Bin Suroor’s True Story and Be Ready non-runners, Goldolphin is represented by the Charlie Appleby-trained Outstrip, winner of last season’s Breeders’ Cup Juvenile Turf at Santa Anita. He has good speed in his pedigree and must be respected here.
The William Haggas-trained Ertijaal has successfully stepped up to 7 furlongs this term in Listed company on the all-weather and is where he should be in our table to excel at a mile, but he will need to learn to settle at this trip.
Charm Spirit and Bookrunner remain in the mix for France. Charm Spirit is a son of Invincible Spirit out of a Montjeu mare and will get this trip and further. The Caradak colt Noozhoh Canarias who split Karakontie and Charm Spirit in last season’s Grand Criterium represents Spain. He has good stamina in his pedigree (he is the only one with a negative CD, at the top of our table, now that True Story is out), but is another that will need to learn to settle to be effective at a mile or more.

Sweet spot


The average DI for the past ten 2,000 Guineas winners is 1.75 (see table), but those with a slightly higher DI than the average (up to about DI 2) seem the ideal type for this race. Of the past 10 winners those that fall within a typical range on this measure are: Dawn Approach (DI 1.67), Makfi (2.11), Henrythenavigator (1.92), Cockney Rebel (1.91), George Washington (1.67) and Haafhd (2.33). Frankel and Camelot were atypical winners on identical DIs of 0.94 (indicating greater stamina potential than is usually associated with this race). It is a mark of the raw ability of that pair rather than appropriate stamina aptitude that enabled them to win the spring classic.

Year       Colt                                         DI
2013       Dawn Approach                       1.67
2012       Camelot                                  0.94
2011       Frankel                                   0.94
2010       Makfi                                      2.11
2009       Sea The Stars                         3.00
2008       Henrythenavigator                    1.92
2007       Cockney Rebel                        1.91
2006       George Washington                 1.67
2005       Footstepsinthesand                 1.08*      (from 1.77)
2004       Haafhd                                    2.33

Average                                              1.75

* Adjusted for the inclusion of Rainbow Quest as a Classic/Solid chef-de-race (see www.chef-de-race.com/dosage/chefs-de-race/rainbow_quest.htm)

Summary

Those with a DI of 1.46 to 2.08 make our shortlist this year: Master The World (DI 1.46), Toormore (1.46), War Command (1.61), Kingman (2.08) and Ertijaal (2.08). Of these Kingman, Toormore and War Command are preferred.

Assuming equal ability between Kingman and Australia, Kingman can be expected to prove best over a mile (on a DI of 2.08). Australia would be preferred at middle distances (on a DI of 1.0). But despite being likely to show improvement for stepping up in trip, Australia carries a high level of stable confidence here and should be backed ahead of Saturday’s race for the Derby on the expectation of a decent showing behind Kingman. The same applies to Kingston Hill, who seems better suited to middle distances than the Guineas. At this trip, Toormore and War Command are likely to give Kingman the most to do.

Verdict:


1)     Kingman          
2)     Toormore
3)     War Command
4)     Australia
5)     Kingston Hill

With Australia and Kingston Hill ideally suited to further. (Derby bets assuming satisfactory prep in this.)

Arc: Finding a three-year-old that has hit form at this time of year is a big advantage

Arc: Finding a three-year-old that has hit form at this time of year is a big advantage


ORFEVRE managed to beat the three-year-olds last year, despite finishing runner-up, and on the face of it looks a logical favourite to make amends this time.

However, three-year-olds win this race, having a big advantage at this stage of the season against the older horses at weight-for-age. Since the WFA allowance was changed in 1995, favouring the three-year-old even more than they were before, the score is 14-4 in the classic generation’s favour.

Half the field is made up of three-year-olds this time so it should be possible to find a couple capable of beting the older horses.

The 3yo filly Treve gets a filly’s allowance on top, so she will have to shoulder just 8st 8lb, meaning that Orefevre will have to be 11lb better than her to match her and better than that to beat her. If he really is a stone better than her he has a chance, but he will have to run the race of his life to prove it.

There are also eight better than useful colts in the field. Of these, Japanese raider Kizuna is well fancied. Andre Fabre is represented by four of them (in addition to a 5yo) and all are up to scratch.

Aidan O’Brien runs two – the Derby winner Ruler Of The World and the St Leger winner Leading Light. Both of these have run into form at the right time. Backing both of these should prove value. Leading Light will relish the going and must be backed each-way.


P.S.     The draw is nothing to get excited about (don’t believe too much what they are telling you!). If they are good enough they can win from pretty much anywhere. Sagace was able to win from berth 17 and Carroll House from 16 and four more (in the past 29 renewals from either 14 or 15). In fact no less than eight have won from a double-digit draw of the past 29 (1984-2012):

St Leger 2013 Preview

Eye Of The Storm and Excess Knowledge are the selections with regard to stamina aptitude

Eye Of The Storm, Feel Like Dancing and London Bridge have not been declared leaving 11 to line up on Saturday.

Excess Knowledge to pass Town Moor stamina test 


THE DOSAGE system comes into its own when analysing Group races that require a test of stamina. It is particularly useful when there is scant form at the distance to go on and in situations where those taking part are still largely unexposed. Indeed, there are few, if any, races in which the Dosage gives us more of an edge than the St Leger.

The race is no respecter of class and quality thoroughbreds that have been successful at shorter trips, including Derby and Oaks winners, have been found wanting in this, including Camelot last season when falling short of the elusive Triple Crown. Perhaps partly because the race can embarrass many of the best, connections of good horses have been prone to turning their backs on it.

Winning criteria

The average Dosage index (DI) for the past 19 winners of the race is 1.08 (a little lower than the average for the Derby) with the ‘right types’ having a DI below 1 (the lower the DI the more stamina aptitude). Of these past winners, the overwhelming majority satisfy the requirement of a DI of about 1 or lower – they comprise: Encke (DI 1.05), Masked Marvel (0.68), Mastery (1.00), Conduit (0.76), Sixties Icon (1.00), Scorpion (1.00), Brian Boru (1.05), Bollin Eric (1.00), Milan (0.77), Millenary (0.83), Mutafaweq (1.07), Nedawi (0.92), Silver Patriarch (1.00), Classic Cliché (0.83) and Moonax (0.73).

The table shows the 14 remaining in this season’s final classic. As usual, it is arranged with those showing the most stamina potential at the top and the least at the bottom, ranked in order of DI.

Key to Profile: Left to right columns, ranging from speed to stamina: Brilliant, Intermediate, Classic, Solid, Professional. DI = Dosage index; CD = Centre of distribution.
The Centre of Distribution (CD) scale complements the DI. The CD covers the range from +2 to -2, where +2 corresponds to the Brilliant aptitudinal group in the Dosage profile (DP), +1 corresponds to Intermediate, 0 corresponds to Classic, -1 corresponds to Solid, and -2 corresponds to Professional. A low (close to zero) or negative CD indicates enhanced stamina potential.


While the David Wachman-trained Galileo Rock hasn’t won a race this season he has been placed in the Derby and its Irish equivalent. The Galileo colt is out of a Groom Dancer mare and should have no problem with the St Leger trip, with eight points in the stamina wing of his profile and a negative centre of distribution (CD). In the absence of Ruler Of The World and Trading Leather he carries the standard for classic middle-distance form to the race.

John Gosden’s Excess Knowledge, who heads our table for stamina aptitude, has been asked to run at inadequate trips to date and just failed to catch Cap O’Rushes in the Gordon Stakes at Goodwood. The son of German stallion Monsun will relish stepping up to this. Cap O’Rushes could finish only sixth of seven in the Great Voltigeur and may have been unsuited by the fast going at York. By Derby hero New Approach out of a Shirley Heights mare he also ought to stay.

Libertarian was a good winner of the Dante when beating Trading Leather and finished runner-up in the Derby, but was very disappointing at the Curragh when struggling a long way out. Another by New Approach (himself a son of Galileo) with strong dam side stamina influences through the Darshaan-Shirley Heights line. Only Excess Knowledge heads him in our stamina aptitude table.

The Aidan O’Brien-trained Queen’s Vase winner Leading Light is unbeaten this season. The Montjeu colt, out of a Gone West mare (coincidently the two latest stallions to be handed chef-de-race status, see http://www.chef-de-race.com/dosage/chefs-de-race/montjeu.htm  and http://www.chef-de-race.com/dosage/chefs-de-race/gone_west.htm), will have no trouble at this trip, with no fewer than 13 points in the stamina wing of his profile.

Leading Light’s stablemate Foundry was an eye-catching runner-up on only his second racecourse appearance to Telescope in the Great Voltigeur, with Godolphin’s Secret Number half-a-length away in third in what appeared to be a strong renewal. The York race is a pretty good trial for the St Leger. Reference Point succeeded in landing the double in 1987 and since then four others have followed suit – Bob’s Return, Milan, Rule Of Law and Lucarno – while another seven – Snurge, Mutafaweq, Silver Patriarch, Bollin Eric, Brian Boru, Mastery and Encke – were no worse than fourth in the Voltigeur before following up in the final classic.

Foundry was touted for the Derby early this season and has an ideal Dosage profile for that race. Despite notable failures, Derby types can also step up to effect in this, with many past winners and placed horses having a DI of about 1. However, the ideal DI for this race would be below 1, given a suitable representation from this category, which is certainly the case in this year’s race.

Eye Of The Storm, another from Ballydoyle, hadn’t been seen out since April when splitting Sugar Boy and Galileo Rock in the Sandown Classic trial, until finishing runner-up in a Listed race against older horses on Monday at Galway. He is bred for stamina and is one of several in the race that has Shirley Heights as a prepotent stamina influence on the dam side. The colt is unexposed and has been tried at inadequate distances to date. Unfortunately the St Leger is likely to come too soon for him, but the colt would hold strong chances if lining up.

Feel Like Dancing won his most recent race at Newmarket for trainer John Gosden and owner/breeder Lady Bamford. The colt is bred on the same Galileo/Darshaan cross as Telescope, out of different mares, he features prominently in our table and will not fail through lack of stamina.

The Brian Meehan-trained Great Hall won last time out at Haydock over 14 furlongs in handicap company. By Halling out of a Machiavellian mare, he is not without chances, but others make more appeal in this.

The Ralph Beckett-trained Talent is the only filly that could still make the line up. We marked her out earlier in the season as a decent prospect at a mile-and-a-half. She was staying on strongly when taking the Oaks and should give herself chances of getting the trip here with a typical DI for this race, if putting her Irish Oaks flop behind her. She would become the first Oaks winner to beat the colts in the St Leger since User Friendly in 1992.

Speed/stamina balance

The average DI for the past 19 winners is slightly above 1, with the ideal type for the race below 1.

Shortlist

With regard to stamina suitability those in the top half of our table are best placed: Excess Knowledge (DI 0.49), Libertarian (0.65), Feel Like Dancing (0.67), Eye Of The Storm (0.71), Galileo Rock (0.78), Cap O’Rushes (0.87), Talent (0.90), Leading Light (0.96), and Foundry (1.0).

Conclusion

Of these, Foundry probably has the most scope for improvement having raced just twice, but his stablemate Eye Of The Storm is also unexposed and is bred for a test of stamina, while the Aidan O’Brien-trained Leading Light has done nothing wrong and indeed everything right in landing the Queen’s Vase and remaining undefeated this season. All three are similarly rated and the one who is improving most at this stage of the season will win the day from the Ballydoyle trio. Excess Knowledge has been run at inadequate trips and is fully entitled to make his presence felt here, as is Galileo Rock, while the filly Talent should not be dismissed. With not much to choose between them otherwise we look to the top of our stamina aptitude table. In the absence of Eye Of The Storm Excess Knowledge is taken to see off a strong Ballydoyle challenge, with Galileo Rock and Talent the next best.

Verdict:

1)     Excess Knowledge
2)     Foundry/Leading Light
3)     Galileo Rock

Royal Ascot, Gold Cup preview

Royal Ascot, Gold Cup preview

The four-year-olds Estimate and Last Train get chance to shine at a trip made for them


Estimate to pass endurance test


Retired US jockey and trainer, Danny Perlsweig, once noted that a horse can get any distance if you give it enough time! This grasps an essential truth that the perceived attributes of speed and stamina are far from mutually exclusive and in fact should rather be seen as a form or expression of the same thing, that of endurance under stress (with stress defined as sustained pace).

While few thoroughbreds genuinely stay 20 furlongs, the horse able to sustain the greatest overall pace at the distance will win.

It is rare for a horse to be able to give optimum performance when asked to endure extreme distance at the sort of pace required for a Group 1. Something invariably has to give. Consequently it is common for horses that do manage to get the balance about right to win the race more than once (Yeats, Royal Rebel, Kayf Tara, Drum Taps, Sadeem, Gildoran, Ardross, Le Moss and Sagaro have all won this race at least twice since the mid-1970s).

The table includes the 19 still in this year’s renewal [Pale Mimosa now a non-runner]. As usual it is organised with those showing the greatest stamina potential at the top, ranked in order of Dosage index (DI). Note that the top eight have negative centres of distribution (CD), indicating pronounced stamina aptitude.

Key to Profile: Left to right columns, ranging from speed to stamina: Brilliant, Intermediate, Classic, Solid, Professional. DI = Dosage index; CD = Centre of distribution.
The Centre of Distribution (CD) scale complements the DI. The CD covers the range from +2 to -2, where +2 corresponds to the Brilliant aptitudinal group in the Dosage profile (DP), +1 corresponds to Intermediate, 0 corresponds to Classic, -1 corresponds to Solid, and -2 corresponds to Professional. A low (close to zero) or negative CD indicates enhanced stamina potential.

The Saeed Bin Suroor-trained Colour Vision saw off Opinion Poll and Saddler’s Rock to land this last year. The five-year-old gelding’s sire and damsire, Rainbow Quest and Monsun, are Classic/Solid chefs-de-race (chiefs of breed) and consequently the gelding has a particularly high concentration of 18 points in the stamina wing of his profile putting him on a prime DI of 0.64 for victory here, as highlighted in last year’s column on this race. However, he has proved unsuccessful in five outings since winning this.

Times Up got the better of High Jinx by a neck in last season’s Doncaster Cup and was earlier successful against the same opponent in York’s Lonsdale Cup. On respective DIs of 0.65 and 0.52 they flank Colour Vision in a sweet spot in our table.

The John Oxx trained five-year-old entire Saddler’s Rock had to narrowly give best to the Godolphin pair in this last season. Although he reversed form with Colour Vision at Goodwood at the beginning of August he has not made the frame in six subsequent starts. But he relishes a test of stamina and is useful.

Rite Of Passage, the winner of the 2010 Gold Cup has raced only twice since that victory winning the Long Distance Cup at Ascot last October. He clearly stays very well, even better than the Dosage suggests. The nine-year-old gelding has won four of his five starts on the Flat, finding only Fame And Glory too good. He goes for this without a prep.

Her Majesty the Queen’s Monsun filly Estimate appears at the head of our table for stamina aptitude. The Sagaro Stakes winner is out of the Darshaan mare Ebaziya and consequently a half-sister to the entire Enzeli, who won this in 1999. She is yet to race beyond two miles, but the four-year-old filly is likely to excel at this extended trip with a Dosage reading for extreme stamina potential. Sir Michael Stoute is a previous winner of this race with Shangamuzo in 1978. The last filly to win the Gold Cup was Indian Queen when landing odds of 25/1 in 1991.

Pale Mimosa is another four-year-old filly that will not only stay the distance but improve for stepping up in trip. Dermot Weld’s charge, by Singspiel, is a relatively unexposed winner of three of her five appearances. The top half of her pedigree is key to her chances here.

The Willie Mullins-trained Simenon was a dual Royal Ascot winner last year and ran a terrific race when fourth under top weight in the Chester Cup last time out. The six-year-old gelding appears to come into his own at trips above two miles, but on a pure Dosage reading others are preferred at this level.

The David Lanigan-trained Biographer is a son of Montjeu out of a Seeking The Gold mare. The colt is a progressive middle-distance to staying sort and may improve again for stepping up in trip.

Andreas Wohler intends to run the seven-year-old gelding Altano, who may be joined by dual Group 1 winning stablemate Earl Of Tinsdal, providing there is enough give for this soft ground specialist. Both have points in the stamina wing of their Dosage profiles.
Top Trip is expected to represent trainer Francois Doumen. The colt has won at 11 furlongs at Group 2 level in France and was beaten a nose in the Yorkshire Cup last time out. By Dubai Destination out of a Kahyasi mare, a mixture of speed and stamina influences are evident in his profile.

France is also represented by Andre Fabre’s Last Train and Mikel Delzangles Vadamar. Last Train is an exciting Group winning colt at two miles, by Arc winner Rail Link, with another Arc winner in Rainbow Quest as his dam sire. The Dosage gives him good chances of improving again when tried at this trip. Vadamar is a five-year-old Group 2 winning gelding by Dalakhani who won a conditions race last time out. He should stay beyond middle distances.

Ballydoyle’s Imperial Monarch has been denied his chance of appearing here, but his stablemate El Salvador could take part. By Galileo out of a Kris mare the colt has won at 13 furlongs on heavy going, but others are preferred in this.

The Sir Mark Prescott-trained Repeater, by Montjeu out of a Mark Of Esteem mare, should also stay well enough in theory but may be out of his depth in terms of class.

Negative centre of distribution

If (in crude terms) a Dosage index of 1.0 and a centre of distribution of zero is the blueprint for a Derby contender, for a potential Ascot Gold Cup winner we are looking for a DI of less than 1 and ideally a negative CD (the last couple of winners are ideal examples of what we should be looking for). Past winners of the race conforming to this ideal are: Colour Vision (DI 0.64, CD -0.13), Fame And Glory (0.65, -0.25), Papineau (0.88, -0.04), Enzeli (0.54, -0.45), Celeric (0.00, -1.44), Double Trigger (0.21, -1.40) and Arcadian Heights (0.90, -0.05) – while Yeats (0.89, +0.08), Kayf Tara (0.90, +0.08) and Classic Cliché (0.84, 0.00) qualify in terms of DI and are very close to qualifying in respect of CD.

Average                                                                                0.93

Shortlist

There are eight in this year’s race with negative CDs and a DI of below 1: Estimate (DI 0.27, CD -0.81), High Jinx (0.52, -0.31), Colour Vision (0.64, -0.13), Times Up (0.65, -0.21), Last Train (0.68, -0.19), Pale Mimosa    (0.80, -0.08), Repeater (0.80, -0.06) and Saddler’s Rock (0.83, -0.02), with others such as Altano close to qualifying.

We shouldn’t ignore Estimate’s reading for pronounced stamina potential and consequently side with the Queen’s filly. Colour Vision and Rite Of Passage have obvious chances, as past winners of this, if capturing past form, as does Saddler’s Rock. Times Up and High Jinx flank Colour Vision in a sweet spot in our table, Pale Mimosa is unexposed and will stay the trip well and Last Train is an exciting contender who should be right there when push comes to shove, at a big price for place backers.

Verdict

1)     Estimate                      
2)     Last Train         
3)     Saddler’s Rock
