EMMA Stewart recorded her 300th training win of 2017-18 on Sunday, the most wins an Australian trots trainer has produced in a single season.

Only hours after claiming three Group 1 titles at Saturday night’s TAB Breeders Crown it was back to business for the Ballarat trainer on Sunday at Warragul, where she achieved the unprecedented milestone with Tiger Storm winning the Leonie Collins and Deb Quinlan 2YO Pace.

The victory moved Stewart past the record set by Queensland trainer Bill Dixon in 2010-11, with Stewart amassing the triple century from just 772 starts, a remarkable 39 per cent win rate.

The achievement, fittingly recorded on the Warragul club’s women’s celebration day, is testimony to Stewart and her great partnership with Clayton Tonkin, who said they had a real “passion for it and I’m sure when success follows you, you want to work hard because it’s something you love”.

Saturday night’s TAB Breeders Crown delivered three Group 1 wins to Stewart’s stable, with Ride High winning the showcase IRT three-year-old colts and geldings final and Lauriston Bloodstock speedsters Speak No Evil and Hurricane Harley claiming their divisions.

“(Ride High’s) very special to us, for him to win I’m very excited,” Stewart said.

“We just let him mature and he’s only had a handful of starts and he just keeps getting better and better.”

Tiger Storm’s victory that brought up the 300 was fittingly steered by reinsman Chris Alford, boosting his season win tally to 447, a national driving record that by Friday’s season end will be a mark that many think will never be bettered.
