Superstar Leo

Superstar Leo began her racing career in a maiden race at Windsor in May, in which she led a furlong out but was caught in the closing stages and beaten a head by Flying Millie. Two weeks later she recorded her first win at Catterick. On this occasion she took the lead from the start, went several lengths clear, and was then eased down in the closing stages to win by three quarters of a length.[9] A week later she returned to the same course and won again, pulling clear inside the last furlong to win by five lengths.[10]

Superstar Leo was then sent to Royal Ascot where she was moved up to Group Three class for the Norfolk Stakes. She was settled behind the leaders by Richard Quinn and sent to the lead a furlong out. She quickened well and won by one and three quarter lengths from Bouncing Bowdler.[11] Haggas commented that she had won "a bit easily"[8] After the race she was sold to Roy Jackson's Pennsylvania-based Lael Stable[12] after her connections received an offer that was reportedly "too good to refuse".[4]

Her next target was the Weatherbys Super Sprint at Newbury. This race is restricted to two-year-olds who have been sold at auction, with the basic weights being set by the sale price. As Superstar Leo had been a relatively cheap yearling, the race was an obvious target. The race also attracted the Queen Mary Stakes winner Romantic Myth, who was made 10/11 favourite ahead of Superstar Leo on 9/2. Haggas admitted that he had avoided taking on Romantic Myth at levels at Royal Ascot, but was prepared to take her on with a five-pound weight advantage.[13] Michael Hills held Superstar Leo up in the early stages before making a challenge in the last quarter mile. The filly took the lead and went clear, being driven out by Hills to win by three and a half lengths with Romantic Myth sixth.[14] The winning time of 59.19 broke the track record by over a second.[4]

All of Superstar Leo's starts so far had been at the minimum distance of five furlongs: in her next race she was moved up to six furlongs for the Group One Phoenix Stakes at Leopardstown in which her main rivals were expected to be the Cherry Hinton Stakes winner Dora Carrington and the Aidan O'Brien-trained colt Minardi. She had no chance with Minardi,[15] who won by five lengths, but finished second of the ten runners. She was returned to five furlongs for her next race, the Flying Childers Stakes at Doncaster. She was made 2/1 favourite and led all the way to win the Group Two race by three-quarters of a length.[16] Haggas paid tribute to the filly afterwards saying, "horses like her come around only rarely and we're very lucky to have her."[1]

Two-year-old racehorses typically race against their own age group. The absence of Group One races restricted to two-year-olds over five furlongs however,[1] has led some trainers to try their sprinting juveniles in open age competition. Notable successes for this strategy have included Sigy in the Prix de l'Abbaye de Longchamp and Lyric Fantasy in the Nunthorpe Stakes. This was the plan adopted by William Haggas for Superstar Leo, who was entered for the Prix de l'Abbaye. In the Longchamp race Superstar Leo was prominent from the start, and Michael Hills moved her up to take the lead at half way. A furlong out she was caught and overtaken by the Irish-trained four-year-old Namid but she ran on well to finish second, one and a half lengths behind Namid, but three lengths clear of the rest of the field which was headed by the Haydock Sprint Cup winner Pipalong.[17] Haggas called her performance "a fantastic run" and added that he was "absolutely thrilled" with the filly.[18]

As a three-year-old, Superstar Leo failed to recapture he two-year-old form. She was unplaced behind Cassandra Go in the Temple Stakes (a "credtable" run according to the Telegraph[19]) and the King's Stand Stakes, before being dropped down to Listed level to finish second in a race at Chester in July. A week later she finished fourth to Invincible Spirit in the Listed Hackwood Stakes before ending her career by running unplaced in the King George Stakes at Goodwood.

In August it was announced that she would be retired to stud.[20]
