With Rich Tapestry's final workout before Saturday's Breeders' Cup complete, trainer Michael Chang Chun-wai was left to "pray to the racing gods" and wait through a nervous 48 hours with a horse he says is in peak condition.

Nearly a month since the six-year-old scored a first-up Grade One win at Santa Anita, Rich Tapestry was galloped on the same dirt surface where he will contest the US$1.5 million Xpressbet Sprint.

"I've done all I can, the horse is as good as I can get him," Chang said. "Now we just have to wait and pray everything stays good."

Earlier in the morning Chang's trackwork rider Vincent Sit Shun-keung rode Rich Tapestry through a brisk gallop aimed at clearing the gelding's airways and was content with the comfortable workout.

"He likes the surface here even more than Sha Tin, it is a little bit softer," Sit said.

Rich Tapestry set off from the 1,200m, building up speed to the 400m and then stepping it up a notch and running 13.2s from the 400m to the 200m mark and zipping home his last 200m in 12.1s without being pushed.

"It was good work and we are very happy with him," the former jockey said.
