With his Sunday treble, trainer Jason Ong has inched closer to No. 3 in the trainers' premiership table.

With 20 winners, the 33-year-old Singaporean has leapt from 11th to joint-fifth with Japanese trainer Hideyuki Takaoka.

The duo are just three winners behind Australian Daniel Meagher and one behind New Zealander Stephen Gray. The two expatriate trainers are in third and fourth positions respectively.

Three-time champion Mark Walker saddled Maximillian to level up with long-time leader and reigning champion Michael Clements on 49 winners.

But Walker gets the top berth on countback for seconds. The New Zealander has 52, twice that of the Zimbabwe-born naturalised Singaporean's.

It is a great achievement by Ong, considering that this is only his third season, after taking over from his retired Kiwi mentor Bruce Marsh.

Sunday's three-timer with Special Ops, Hosayliao and Universal Empire was the second in Ong's career. His first was with Try Mak Mak, Miss Michelle and Kiwi Kid on Oct 31 last year. He saddled five doubles this year.

"Yes, it was a very good day for all connections. There are still three months to go, hopefully, it stays that way," said Ong, on his winning streak.

Special Ops' comeback victory in the $50,000 Class 4 Division 2 race over the Poly 1,200m brought plenty of cheers.
