RENO, Nev. (AP) -- John Rollins doubled his lead in the Legends Reno-Tahoe Open, shooting a 5-under 67 on Saturday to move four strokes ahead of Ryan Palmer.
Rollins, who tied the course record with a 62 on Friday, had three birdies and three bogeys on the front nine, then rolled in a 30-foot eagle putt on the par-5 11th and added two birdies to finish at 17-under 199 at Montreux Golf & Country Club.
Palmer started the day five strokes off the lead, but birdied three of the first four holes and shot a 66 to reach 13 under.
Joe Ogilvie was another stroke back after a bogey-free 66 that included an eagle and four birdies. Martin Laird (66) was 11 under. He finished birdie-birdie-birdie-eagle, holing a 77-yard approach to the par-4 18th that spun back 20 feet into the cup.
