Finally, good weather showed up on Saturday -- sunshine, the thermometer near 70 degrees, and little breeze. The ideal conditions led to more red numbers, including Mathias Gronberg's 64, the low round of the tournament to that point.
Taylor didn't join in the fun, though, only managing a 71 and getting passed in the process. Kuchar put together a bogey-free 67 and moved into a tie for the lead with Scott Piercy at 14-under-par 202. They led Olson and Rod Pampling (who fired a 65) by one shot with 18 holes to play.
As it turned out, they would need a lot more than 18 holes to resolve matters. It was an exciting Sunday, where Peter Lonard's course-record 63 (he tied for 12th at 275), plus low rounds by Jeev Milkha Singh (64), Webb Simpson, Harrison Frazar and Bo Van Pelt (65 each), set the tone for the craziness to follow.
Piercy, trying for his first PGA Tour win, slumped to a 73, while Kuchar worked through two early bogeys and kept a share of the lead through much of the front nine with a revolving door of contenders, including Singh, Thompson and Olson.
Then Kuchar caught fire at the turn, with three straight birdies on 8, 9 and 10. As that was happening, though, Taylor and Petrovic were both sliding back into the picture with their own set of birdie.
As Kuchar was playing the 9th, a roar went up from the 12th. On that par-five, Taylor's 70-yard wedge shot took one hop and dove into the hole for an eagle, briefly giving him the lead before Kuchar's own birdie charge put him one ahead of Taylor and Petrovic.
Taylor bogeyed 15, briefly putting him two back, but he birdied 16 and, just as Kuchar was making a sloppy bogey on 13, Taylor sank another birdie on the par-four 17th to move up to 17 under par, alone in the lead.
