Avdulla went into Wednesday’s meeting after riding his 90th metropolitan winner on Saturday, a goal he said he set himself a year ago.
He appeared to have the 2016/17 premiership in his keeping until Hugh Bowman launched a late charge to overhaul him in the final couple of weeks.
Although the TAB has already paid out on him to win the title, Avdulla is not being complacent this time around and admits he let it get away last season.
“I had 78-1/2 winners last year when Hughie got me late,” Avdulla said.
“I set myself a goal that 90 winners was realistic.
“I thought that whatever comes with riding 90 winners is what comes of it. If that’s the premiership then so be it.”
Avdulla’s Warwick Farm winner came on Godolphin’s Osorno while Shinn scored on the Peter and Paul Snowden-trained Island Missile.
But riding honours on the day went to Bowman who has returned to Sydney racing after a stint in Japan and a short holiday.
Star Of The Seas is by 2012 Cox Plate winner Ocean Park, a son of Spieth’s sire Thorn Park with both out of Stella Livia.
The three-year-old’s career has been restricted to three starts so far but Waller believes he can go on with it after a wind operation.
“He won with a bit of class,” Waller said.
“Horses like him are what racing is about and he can win good prize money.
“He is owned by Tony Muollo who doesn’t like a lot of publicity but he owned my first horse to win in Sydney, Party Belle.
“He has been a great supporter of mine.”
