A race devised to showcase future staying talent served its purpose for trainer Guy Walter after emerging filly Knead The Dough won at Rosehill on Monday.

Knead The Dough reacted positively to a mid-race move from Nathan Berry to win the Significant Stakes, a 1900m race for two and three-year-olds.

Allowed to stride forward and contest the tempo outside the leader Dana's Best, Knead The Dough, the best-backed runner ($3.90 to $3.10 fav), surged away in the heavy conditions to defeat Medvedev ($3.50) by three lengths.

The win was a continuation of the New Zealand-bred's top off-season form with the filly posting her fourth win in seven starts since resuming at the provincials in March.

Her run through grades hasn't been entirely unexpected, given Walter is already thinking about next season with the three-year-old.

"I think we'll just poke along through the winter and after a spring spell there might be a nice race in her next autumn," Walter said.

"She seems to relish the heavy conditions but that aside she's a lovely filly with plenty of potential."

Berry, who has ridden Knead The Dough to wins at her past two starts, said the filly often had a mind of her own.

"She likes these tracks, these conditions but the key to her is not to fight her," he said. "There is no point in fighting her, you just give her rein."

Knead The Dough wasn't the only established wet tracker to enhance a reputation as a mudlark during the postponed meeting.

World Wide made it five wins from as many starts in heavy going in the Calcoup Knitwear Handicap (1900m) after making his own luck under Kathy O'Hara.

Hitting the front at the 400m, World Wide ($4.80) established a winning break and held off Lucripetous ($6) to win by three-quarters of a length.

Lucripetous was one of three early placegetters for Chris Waller who needed three winners going into the meeting to set a Sydney trainers' record.
