GAI Waterhouse and her new co-trainer, Adrian Bott, have had immediate success, winning a stakes race at the first Saturday meeting of the new season.

Saddling up the three-year-old Snitzel colt Thronum in the Listed Rosebud over 1,200 metres at Rosehill, the win was described as “essential” by Waterhouse. “We knew we had Thronum there and we knew he could be our first winner together,” she said.
