The Chris Waller-trained Rangirangdoo broke through into Group 1 territory for the first time on Saturday when he secured a tight but thrilling win in the $1.5 million Group 1 Doncaster Mile (1600m) at the Royal Randwick racecourse.

Five-year-old Rangirangdoo had previously placed second in three Group 1 features, including his last start runner-up to Theseo in the Ranvet Stakes.

But on Saturday Rangriangdoo ($6) answered all those who doubted he had a Group 1 win in him, when he fought hard to the line, beating home Anthony Cumming?s Road To Rock ($26) by just a half-neck with Brilliant Light ($15) a gallant third one and a half lengths away.

Five-time Group 1 winner Typhoon Tracy, the highly fancied $3.30 favourite on Saturday, was stepped on during the race and pulled up hard on the straight to finish a disappointing 14^th.

Rangirangdoo was ridden by close-race-finish expert Nash Rawiller after Waller fought for his right to keep Rawiller aboard Rangirangdoo in the Doncaster Mile. A challenge by rival trainer Gai Waterhouse when she decided to run Theseo in the race, led to a tug-of-war over her stable jockey Rawiller in a Supreme Court Hearing.

Theseo ended up running eighth in the Doncaster on Saturday with Darren Beadman aboard.

In another controversy from Saturday, Damien Oliver, the hoop aboard runner-up Road To Rock, is facing a steward?s inquiry after weighing in nearly a kilo over his mount?s 54kg handicap.

Waller had two of his other horses run in the race, with George Ryder Stakes winner Danleigh finishing a solid fifth and 2008 Doncaster Mile victor Triple Honour also holding their own in seventh.

Rangirangdoo, sired by Pentire out of She Wishes, has now won over $1.73 million in prizemoney for his connections after winning nine of his 19 career starts.

Waller is considering next Saturday?s $350,000 Group 1 Queen Elizabeth Stakes (2000m) as a final autumn run for Rangirangdoo, and will make a last minute decision based on the gelding?s health and fitness over the next week.

Randick?s meeting on Saturday featured two other great Group 1 races. In the $350,000 AJC Australian Oaks (2400m) the brilliant Gai Waterhouse-trained Once Were Wild, also ridden by the in-form Nash Rawiller, secured her sixth career win from just eight starts, while four-year-old Ortensia claimed victory in the $300,000 The Galaxy (1100m).
