St Leger preview

Tenacious Stars represents Classic form and shows solid middle-distance stamina

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 races in which the system gives us more of an edge than the Ladbrokes St Leger.

Winning criteria

The average Dosage index (DI) for the past 10 winners of the race is 1.04 with the ‘right types’ having a DI of below 1 (the lower the DI the more stamina potential). Of recent past winners, the overwhelming majority satisfy the requirement of a DI of about 1 or lower – they comprise: Kingston Hill (DI 0.90), Leading Light (0.96), Encke (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 eight still in contention for 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. This year several of the profiles have the look of middle-distance performers rather than dyed-in-the-wool stayers. Relative stamina performance will nevertheless play a part.

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.

Solid form

The winner of York’s Great Voltigeur Stakes, Storm The Stars, carries solid Classic form into the St Leger on his placed efforts behind the John Gosden pair Golden Horn and Jack Hobbs in the Derby and Irish Derby respectively. While he has won only three of his 10 starts he has been placed in all but one of his other appearances and has shown a high level of consistency for his trainer William Haggas.

The Great Voltigeur has proven a reliable trial for the final Classic. Since 1971, Athens Wood, Bustino, Reference Point, Bob’s Return, Milan, Rule Of Law and Lucarno have won both races and the likes of Moon Madness, Snurge, Silver Patriarch, Bollin Eric, Brian Boru, Mastery and Encke, have been placed in the Great Voltigeur before winning the Leger. Being placed in the Derby is also no obstacle to winning at Doncaster, with Shantou, Silver Patriarch, Rule Of Law and last year’s St Leger winner Kingston Hill all managing the feat since the mid-1990s. On this basis, Storm The Stars has excellent credentials for this season’s renewal.

The son of Sea The Stars is out of an unraced Sadler’s Wells mare. Sadler’s Wells is a Classic/Solid chef-de-race (chief of breed) in the Dosage system and the sire of Sea The Stars, Cape Cross, has recently (in August 2015) been established as a Classic chef-de-race. While this doesn’t show bottomless stamina, a DI of 1.07 is well within the acceptable range to be successful in both the Derby and the St Leger, with 10-year average DIs for those races being 1.19 and 1.04 respectively, and middle-distance stamina may be all that is required in this year’s renewal in the absence of true and fully effective stamina types.

O’Brien options

Aidan O’Brien again had plenty of decent Leger prospects to choose from, which has boiled down to three Galileo colts – Bondi Beach, Fields Of Athenry and Order Of St George.

The unexposed Bondi Beach, finished close up to Storm The Stars at York and had previously won the Curragh Cup, albeit narrowly from his stablemate Order Of St George. Despite being bumped and carried across the track by a determined winner at York, Storm The Stars looked to have his measure that day. Bondi Beach nevertheless looks open to further improvement.

Since going down by a short head to his stablemate Bondi Beach, on his seasonal reappearance in the Curragh Cup, Order Of St George has won twice, most recently on his return to the Curragh where he beat Sea Moon by some seven-and-a-half lengths over 14 furlongs. It is unclear at the time of writing which one of the Ballydoyle trio will be their first string. All three are by Galileo and all three have already proved effective beyond middle-distances and as things stand are on official ratings of 115 (Bondi Beach and Order Of St George) and 114 (Fields Of Athenry), setting a level just below that of Storm The Stars on an OR of 116. All three are also within acceptable parameters for winning the St Leger despite appearing in a cluster at the foot of our table.

Fields Of Athenry is a relentless front runner that has won three of his five starts this season and was pitched in against the older horses in the Ebor last time out for his new owner, where he blazed a trail before fading out of the frame. He was far from disgraced, however, registering a very decent RPR of 118 in the process. The three Galileo colts are expressions of middle-distance stamina rather than extreme stamina attributes.

David Brown’s exposed Medrano, winner of two of his 12 starts, looks like a soft ground performer. He won a Listed race at Hamilton in good style before stepping up to Group company behind Highland Reel at Goodwood and Storm The Stars at York. He raced too keenly in the Great Voltigeur and dropped out in the straight. He nevertheless has good stamina potential.

Proposed won a Sandown maiden in May after struggling at Group 3 level, but has finished down his fields since when stepped up in trip. On sub-100 ratings the Invincible Spirit colt is almost certainly not good enough to make an impact here for trainer Richard Hannon.           

Legitimate stayers

At the head of our table the Mikel Delzangles-trained Vengeur Masque has won two of his five starts in France, but has plenty to find with his principal rivals here. However, the son of Monsun is at least a legitimate stayer and should not disgrace himself at the trip with eight points in the stamina wing of his profile and a negative centre of distribution.

The filly Simple Verse, who has been supplemented for the race at a cost of £50,000, should also come into her own at this trip. The Ralph Beckett-trained winner of three of her four most recent races, including the Lillie Langtry Stakes at Glorious Goodwood over 14 furlongs, will attempt to become the first filly to win the race since User Friendly in 1992. A daughter of Duke Of Marmalade out of a Sadler’s Wells mare, and on a DI of 0.88 and a CD of 0.03, she has just the sort of Dosage profile required for the St Leger but will need to progress again in terms of ability with the colts nearer to the head of the market. Beckett has been knocking on the door of the St Leger with his Oaks winners Look Here and Talent who finished third and second in this respectively and victory here is certainly within the realms of possibility.

Speed/stamina balance

The average DI for the past 10 winners is slightly above 1, with the ideal type for the race below 1. A low or negative CD is also an advantage (this is especially true when the race lacks a top-notch middle-distance type that is capable of stepping up; but that does not quite appear to be the case this year with the likes of Storm The Stars and the O’Brien trio taking part).

Average Dosage index      =               1.04

Those with the best stamina credentials this year do not also look the best in terms of raw talent. This is good news for Storm The Stars and the Ballydoyle contingent who fall within the broader category of middle-distance stamina, which is also acceptable for winning this race. Preference is given to William Haggas’s admirable Storm The Stars over the likes of Bondi Beach, Fields Of Athenry and Order Of St George. Ralph Beckett’s progressive filly Simple Verse may prove good enough to make the frame.

Verdict:

1)     Storm The Stars

2)     Bondi Beach

3)     Fields Of Athenry/Order Of St George

4)     Simple Verse
