Argentinian import Quechua won the Longines Singapore Gold Cup on Sunday evening to give trainer Patrick Shaw his second triumph at the $1.35 million race.

The South African handler has come up short in the 2,200m race since his first victory in 2006 with Mr Line but had plenty to celebrate after his four-year-old gelding posted a one-and-a-half length victory in the prestigious Group 1 race at the Singapore Turf Club.

Said Shaw, who bagged a quinella after his other runner Emperor's Banquet finished second: "I'm very happy with the results and both horses really rose to the occasion today. It was always going to be a tough race but they showed their class today."

Pre-race favourite War Affair, bidding to win the Gold Cup and become the first horse to sweep all three legs of the Singapore Triple Crown Series, faltered along the home straight and finished fifth at Kranji.

Winning jockey Corey Brown has now saluted three times aboard Quechua and paid tribute to his mount. He said: "I had a super feeling when I first rode him. He's a proven stayer and I always felt he would be hard to beat in this race."
