Tommy Berry's introduction to Hong Kong racing continues to produce outstanding results for the Sydney jockey.

In a thrilling climax to the Sha Tin Vase at Sha Tin on Sunday, Berry helped Charles The Great gain a narrow verdict in a blanket finish that involved seven horses.

As a cavalcade of horses flashed past the winning post, it was Berry's mount, widest of all after a surging centre-track run, who snatched it by a short-head.

"It probably wasn't the prettiest run, four deep with cover, but they were bunched up and we were close enough if good enough," Berry told the Hong Kong Jockey Club.

"He's a horse down at the bottom of the weights that's been in very good form (and) even though it was a big step up, horses in form are always the ones to follow."

Berry has been an instant hit since taking up a short-term contract to ride in Hong Kong.

He announced his arrival straight after the Sydney autumn carnival with a Group One win on Military Attack in the QEII Cup on his first day of riding in Hong Kong.

Charles The Great's victory took Berry's Hong Kong tally to six wins from 66 rides.

The win marked a career peak for the John Moore-trained Charles The Great, who carried 117lbs to prevail in a time of 1 minute 08.94 seconds from the Tony Cruz-trained Best Eleven, with stablemate Captain Sweet a further short-head back in third. Half a length covered the first seven home.

Finishing among the unplaced division was another stablemate Time After Time, a horse Moore says in still in the running for a trip to Royal Ascot to contest the Diamond Jubilee Stakes.

"My impression would be to go on that run ... that was a beauty," the trainer said.

"Now we need to speak to the syndicate and get the green light and if he does he'll fly out on June ninth."
