Flesch - in command going into the final round.

Sky Bet's Odds Compare All Prices

Steve Flesch is a top-priced 3/10 with Sportingbet to win the Turning Stone Resort Championship heading into the last round.

Flesch will take a four-shot advantage into the final 18 holes after firing a six-under-par 66 on Saturday.

He carded seven birdies and a bogey to open up the four-shot cushion over Carl Pettersson, who also signed for a 66, and Charles Warren.

Flesch is now as short as 2/11 in places and no better than 3/10, while Pettersson is a general 6/1, Warren is on offer at 8s and it's virtually any price the rest who are all at least six shots adrift.

"This is the second time this year I've had a lead like this," said Flesch. "It is different this time. The first time, I was playing to secure my card and keep my job. I'm just having fun this week. I've got nothing to lose. I can just go at it and be aggressive."
