Heavy rain from a late afternoon storm helped Osborne's cause with Written Up relishing the soft track.

"The wet track was a bonus but the good barrier became a question mark," Osborne said.

"Jamie (Mott) rode him terrific and got off the fence."

Written Up ($11) held off Gracious Prospect ($31), with Mahican third.

Written is part-owned by Bendigo businessmen Chris Morey and Terry Hurford.

A son of Written Tycoon, Written Up's only previous run on a wet track was a win on debut at Bendigo.

"This race and his next run in a VOBIS Gold race at Flemington were the two races we had picked out for him,'' Osborne said.

"I was confident he'd run well today, but these races are very hard to win."

Signoff will be aimed at October's Jayco Bendigo Cup (2400m) after demolishing its rivals in Saturday's Stayers Championship Final (2400m) at Bendigo.

Raced by Jayco owner Gerry Ryan and sporting the colors of 2012 Bendigo Cup winner Puissance De Lune, Singoff toyed with is rivals in winning its fifth race from just six career starts.

Winning jockey Brad Rawiller heaped praise on Signoff, which is trained by Darren Weir.

"As soon as he gets his rhythm, he feels as good as any horse I've ridden," Rawiller said.

"He travels like a good horse. He still hasn't got there yet, because he hadn't been letting down fully.

"But today was a good step forward."

Signoff ($1.85 favourite) won by five lengths from Beliveau ($8.50), with Mariner ($17) third.

"He's a horse that's shown immense ability from the beginning, but he (Weir) has been putting him through his grades and basically getting him ready for down the track," Rawiller said.

"Because if you throw them in the deep end a bit early they can take two steps backwards."

Bendigo mare Hai Lil ran a gallant third behind Hazard in the $110,000 Catanach's Jewellers Gold Bracelet (1400m).

The Allen Browell-trained mare was forced to go back to last from her wide draw and wasn't helped by a slow tempo up front set by Spirit Song.

Hai Lil's hoop Michael Rodd tried to save ground on the inside before weaving a passage clear at the 200m mark.

Hai Lil flashed home, but she gave the leaders too big a start.

Spirit Song, ridden by Brad Rawiller, appeared to have the race in her keeping, before Hazrd, ridden by Stephen Baster, surged in the final 50m to win by a nose right on the post.
