Apprentice Adam McCabe had to survive a protest on his winning mount Chosen To Fly before securing the third and final leg of the 2011 Asian Young Guns Challenge at Flemington.

Apprentice Katelyn Mallyon, who was not involved in the Challenge, rode Happy Angel ($4.60) and fired in a protest against Chosen To Fly ($9) alleging interference over the final 200m of Saturday's 1000m event.

Racing Victoria stewards, chaired by Terry Bailey, acknowledged that the two horses brushed on three occasions, twice near the 200m and once at the winning post, but stewards ruled the final brush had no bearing on the result.

They ruled the interference was insufficient to exceed the half-neck margin and dismissed the objection.

McCabe, 21, is indentured to Cranbourne trainer Mick Kent and won the Rising Star Apprentices series last season and was runner-up in the Victorian apprentices' premiership behind Jake Noonan.

Katelyn Mallyon is yet to ride her first metropolitan winner but has been going well on provincial tracks and rode a double at Bendigo on Thursday.

Her cousin Jordan Mallyon, who won the opening leg of the Challenge aboard Diamondsondinside and finished third on Sarge In Charge in the final leg, was the overall winner with 41 points over McCabe (36).

Hong Kong apprentice Vincent Ho and Japan's Ryo Takakura were equal third with 31 points.

Jordan Mallyon, 18, is indentured to Flemington trainer Mike Moroney but is currently on loan to Tony Vasil at Caulfield.

The grandson of former top jockey Mick Mallyon, who won three Caulfield Cups, has ridden 105 winners including the 2011 Travis Harrison Cup, an apprentices-only event at Moonee Valley aboard Charlie's Queen.

Chosen To Fly was having his first start for the Colin and Cindy Alderson stable after previously being prepared by Queensland trainer Mick Mair.

The grey, a four-year-old entire by Choisir, was resuming after a seven-month break and took his record to six wins from 13 starts.

He completed a winning double for the Aldersons who earlier scored with the promising Snippetson three-year-old gelding That's The One.

"He's a very good looking horse. He's such a big horse and a long strider and I had a feeling he would like Flemington and that's why he came here today," Cindy Alderson said.

"There might be a race for him here over the carnival later on."

Japanese rider Kota Fujioka took out the inaugural challenge at Flemington in 2009, while last year Hong Kong's Derek Leung was the winner at Kranji in Singapore.
