An all-out assault on par marked Saturday's third round of the Turning Stone Resort Championship - but it was the last birdie streak that had the biggest impact.
Alex Cejka, nearly forgotten in a flurry of low scores, had the best possible finish to seize a two-shot lead over Chris Couch heading into Sunday's final round.
Cejka birdied the 16th, 17th and 18th holes to finish with a five-under-par 67. His 54-hole total of 201, 15 under par, left him ahead of Couch, whose 63 tied the Atunyote Golf Club course record and put him at 203, 13 under par.
Billy Mayfair parlayed a third-round 66 into a third-place total of 204, 12 under par. Four players - Charles Warren, Bill Lunde, Robert Garrigus and Chris Tidland - are at 205, four shots back.
Warm sunshine and blue skies greeted the field of 72 that survived the 36-hole cut. More importantly, the fierce winds that marked Friday's second round were gone, and Atunyote was left vulnerable to golfers hungry to go low.
And go low they did. The field averaged 69.11, more than two shots better than the second round, and that included the four best rounds of the tournament.
Scott McCarron set the tone with an early 64 in the third pairing of the morning, and Lunde also reached that number. Then Warren, propelled by an eagle on the 12th hole, charged home with a 63 to match Peter Lonard's 2009 course record and take the lead an hour before Cejka took off.
With the red numbers so prevalent, four different players would grab the lead during the afternoon, though none of them would finish in front.
Mayfair, who started at six under, had the hottest front nine of the tournament, streaking to a 30 that featured five straight birdies from the 5th to 9th holes. Just as quickly, though, Mayfair cooled off, only making pars the rest of the way.
