Winona Costin showed exactly why the NSW apprentice premiership is at her mercy with a heads-up ride to score on Numbers for her old boss Mick Tubman at Kembla Grange on Tuesday.
Having to shelve all plans to lead after Numbers ($7) couldn't muster speed early, Costin took runs along the inside, then eased across heels to charge home and deny Shane Kember's Tarewa Road ($101) a boilover in the 1200m maiden.
"I think I can read a race quite well for the stage I'm at," said Costin, who's transferred her indentures to Gai Waterhouse. "I've still got a lot to learn, but we're getting there.
" ... At about 150-metres out I thought, 'I've got to take the run here because she's not getting out between all these horses'. I had to half-check her and flew around heels and she flew home," Costin said.
Tubman described his former star pupil's ride an "absolute treat" with a horse who spearheads a small stable he runs at Kembla.
"We've only got a couple of horses now and low in numbers, but we're always confident," Tubman said. "I was panicking half-way through the race as I thought she would be up there with them under the light weight, but she'll run a mile-and-a-half."
