Big-race jockey Glen Boss won the Group One Doncaster Handicap for the third year running when Triple Honour ran away with the $1.8 million feature at Randwick today.
The win was also a triumph for trainer Chris Waller who scored his first success at the elite level.
Boss won the race on Haradasun last year and Racing To Win in 2006 following earlier Doncaster victories on Private Steer in 2004 and Sprint By in 1996.
Three-year-old Triple Honour, who was having just his ninth start for his fifth win, travelled sweetly in midfield for the majority of the 1600m feature until Boss produced him at exactly the right time in the straight and the gelding bounded away for an explosive victory.
Casino Prince ran his usual honest race for second while Pinnacles was third.
"I've had a bit of luck in this race," was Boss' understatement.
"I'm so excited, it's amazing.
"We had a lovely run throughout and once he got through he kicked strongly."
Boss' fifth Doncaster win came just a week after he captured the $3.5 million Golden Slipper on the Gai Waterhouse-trained Sebring.
