The faith Newcastle trainer Dianne Lumsden has always shown in apprentice Serg Lisnyy could be repaid at metropolitan level when they reunite at Warwick Farm on Wednesday.

Lisnyy is making inroads in Sydney under the guidance of David Payne, the Rosehill trainer who was instrumental in the early development of Cox Plate-winning apprentice Chad Schofield.

And his progress has come as no surprise to Lumsden who will start Bench Star with Lisnyy in the saddle in the All Too Hard @ Vinery Handicap.

"I was using him up here before everybody else and I could see there was potential," Lumsden said.

"He was a bit of a wild young fellow there for a while but he's come of age because he's a bit more patient now."

Fresh from riding a winner for Payne at Rosehill on Saturday, Lisnyy has enjoyed success on Bench Star.

He was on board 12 months ago when Bench Star won his first two races but his only ride on the horse since resulted in an inglorious Cessnock performance.

That was the third run of what has turned out to be a 13-start campaign and Lumsden has no plans to spell the five-year-old now that he has found his best form again.

"The owner said to me the other day `it must nearly be time for a spell'," Lumsden.

"The fact that we've just cracked the code with him, I don't think we will be spelling him. Not until he puts in a poor one."

Bench Star strung together Newcastle and Port Macquarie wins before Lumsden rated him unlucky when runner-up at Wyong at his most recent start.

He was city-placed as a two-year-old when trained by Clarry Conners and Lumsden says a metropolitan win would be a deserved one.

"Getting a midweek win with him would be a nice reward for the owner because we told him he might have to show a bit of patience," Lumsden said.
