A return to 1900m saw New Zealand-bred Billy Britain race away to a comprehensive win in the SG$60,000 Open Benchmark 61 race over 1900m on Sunday.

Settled at the rear as is his customary style, the One Cool Cat seven-year-old started to gather momentum from the 800m. Once he was in full flight, there was no stopping the $16 favourite.

The Stephen Gray-trained galloper careered away under Alan Munro towards a most impressive four-and-a-half length win from Mongolian Chief (Glen Boss) with Golden Thunder (Chan Wei Sheng) third another three parts of a length away. The winning time was 1min 58.29secs for the 1900m on the Polytrack.

Gray was certainly pleased with such a resounding win from the St George Stable-owned galloper, but his muted celebrations betrayed some mixed feelings.

"He was back to Class 4 and over 1900m," said Gray.

"It was a good race for him, he loves that sort of race, that is his limit - and he goes good for Alan.

"He was actually meant to go to Malaysia. He didn't have Strangles but he failed the test and couldn't go, and he's now won another $50,000 here.

"He's been a good handy horse for Paul Hickman."

Munro, who was at his third win from six rides aboard Billy Britain, said he just pushed the right buttons at the right time.

"He showed nothing and at the 800m, he suddenly grew a leg," said the English rider.

"At the 400m, he kicked again. It was like he had a full tank of petrol left."

Billy Britain has now taken his record to six wins and 14 placings from 45 starts for stakes money in excess of $300,000 for the St George No 2 Stable.
