Fair Hill Five: US longshots and London wagers prompt HISA probe
Last Sunday at New Jersey’s Monmouth Park and at Saratoga, four longshot horses that had recent workouts at Maryland’s Fair Hill Training Center won unexpectedly and in-person wagers placed across London shops prompted an investigation by the U.S. Horseracing Integrity and Safety Authority (Hisa).
Britain’s Racing Post reported a "six-figure betting coup" after the sequence began with The Great Amira, a 17-1 longshot who won wire-to-wire by nine and a half lengths at Monmouth Park, followed immediately by Tepeyac at about 4-1; later at Saratoga Classic Rock won by nearly nine lengths at 8-1 and M BS Melanie Cares prevailed at 12-1. Scootaloo finished fourth at Saratoga after a poor start and has been described as a runner who might have won with a clean break; subsequent reports linked the operation to Winston Wolf, who finished second at Colonial Downs. All six horses had recorded workouts at the Fair Hill Training Center and were returning from layoffs of between four and nine months.
The six horses produced little recent form: they had finished outside the top three in 16 of their previous 17 races, with only a single third-place finish among them. Angel Quiroz was the listed trainer of The Great Amira, Tepeyac and Scootaloo, while Classic Rock and M BS Melanie Cares were entered by owner-trainer Ernesto Ochoa; Quiroz has acknowledged previously working with both Classic Rock and M BS Melanie Cares in addition to Winston Wolf. Quiroz and Ochoa had each recorded only two winners in all of 2026 before last Sunday, and The Great Amira had finished dead last in her two previous outings, including once by 40 lengths, before the Monmouth victory. The Great Amira, Tepeyac and Scootaloo were also Quiroz’s first starters outside Florida since 2015.
The wagering outcomes exposed a stark difference between US parimutuel pools and UK fixed-odds markets: the $2 Daily Double combining The Great Amira and Tepeyac returned $25.60, compared with $178.56 if the win payout on The Great Amira had simply been rolled over to the next race. A Horse Racing Nation analysis of 1,065 comparable doubles dating to 1998 identified that Daily Double as by far the worst-performing example of its kind in nearly 30 years, but the entire pool contained less than $10,000, meaning a relatively modest wager could produce a freak payout and indicating the exact combination had been targeted without proving large sums were wagered in the US.
Industry sources said at least five bookmakers accepted wagers across 12 brick-and-mortar London shops tied to the Fair Hill runners, with some bettors presenting American identification; those bets were placed as packages of singles, doubles and trebles so parts of the wagers could survive losing selections, and individual stakes reportedly remained below levels likely to trigger bookmakers’ liability checks. Because the money was wagered with British bookmakers rather than through US parimutuel pools, it did not directly shorten the American tote odds and left the scale of overseas betting largely undetectable at the tracks.
British prices diverged sharply from US odds: Classic Rock was 2-1 in Britain but longer than 8-1 in America, and all four winners were shorter-priced with British bookmakers, which strongly indicated concentrated money had been wagered in London. One estimate placed bookmakers’ potential liability at £600,000 to £800,000, although Paddy Power described its own loss as modest.
The operation appeared set to continue on Monday, but Threedots Andadash and Bravo Rough were scratched; those withdrawals did not cancel the bets but reduced them to smaller, less lucrative combinations and stripped away much of the potential return.
The New York Racing Association referred the matter to Hisa, its enforcement arm the Horseracing Integrity and Welfare Unit (Hiwu), and the Thoroughbred Racing Protective Bureau, and all four winners underwent routine post-race drugs testing while Hiwu is conducting additional out-of-competition tests. Investigators will await laboratory results, trace the American and British wagers to establish who placed them and whether they had undisclosed connections to the horses, and the betting trail may depend on information shared by British bookmakers and regulators. Hiwu says results from the recently tested horses will be disclosed under its anti-doping rules; Quiroz has denied any wrongdoing, arguing that he simply entered his horses and tried to win, and racing authorities have reached no conclusion.
