A week of unprecedented drama had a fitting climax when Rangirangdoo claimed the Doncaster Mile at Randwick, with glamour mare Typhoon Tracy out of the picture.

Gai Waterhouse challenged a stewards' ruling that Nash Rawiller was committed to Rangirangdoo in an attempt to get him on Theseo.

The NSW Supreme Court stuck with the stewards' decision and Rawiller showed why he is in such demand when he lifted Rangirangdoo (A$6) over the line half a neck in front of Road To Rock (A$26) with Brilliant Light (A$15) another 1 lengths away third.

More drama followed the race when Damien Oliver weighed in overweight on the runner-up citing the horse's sweating as a cause, with the gear soaking wet.

For winning trainer Chris Waller the victory was sweet after Rangirangdoo's two recent Group One second placings behind Theseo.

"I wasn't on the best angle to see the race and I thought it was going to happen again that he was going to run second," he said. "I thought 'here we go again'.

"When you have three runners in a race like this you try to look at all of them but when you win it, it's so emotional."

One of the first people to congratulate Waller was Waterhouse who watched Darren Beadman ride Theseo into eighth place.

Dominant favourite Typhoon Tracy (A$3.30) was travelling up on the pace rounding the turn but was one of the first horses beaten, eventually finishing 14th.

A veterinary examination showed she had been galloped on.

Waller's other runners Danleigh (A$8.50) and Triple Honour (A$31), winner of the 2008 Doncaster, finished fifth and seventh respectively.

Rawiller, who was called on to replace the injured Corey Brown on Rangirangdoo, said he respected Waller's decision to press to keep him on.

The AJC Australian Oaks was billed as a virtual match race between glamour fillies Faint Perfume and Valdemoro but in the end the Group One Classic belonged to the Gai Waterhouse-trained Once Were Wild.

Still in her first racing preparation, Once Were Wild showed an explosive turn of foot to quickly put yesterday's 2400m race beyond doubt.

Faint Perfume chased gamely but finished 3 lengths away second with a further five lengths to Run For Naara in third.

Valdemoro settled last and was never a factor.

Waterhouse praised stable jockey Rawiller for his winning Oaks ride. "Nash rode her a treat, it was a joy to watch".

Melbourne mare Ortensia has scored a brilliant first-up win in the Group One Galaxy.

Trainer Tony Noonan is considering the Group One KrisFlyer (1200m) in Singapore next month for the 4-year-old after watching her storm home down the outside to claim her first Group One.

Ortensia ($4.40 fav) settled near last in the field of 14 but regular rider Craig Williams took her to the extreme outside where she unleashed her customary finish to reel her rivals in.

She beat Shellscrape by a short neck with a half-neck to Swift Alliance.
