Adam Scott didn't have to look as far down the leader board to find players who suddenly are a real threat to win at Bay Hill.
He described them as players who are "hungry to win," and Scott served them up an appetizer Saturday in the Arnold Palmer Invitational in Orlando, Fla.
Staked to a seven-shot lead at the start of the third round, the Masters champion hit enough loose shots and missed just enough par putts to lose more than half his lead and turn his quest to be No. 1 in the world into a bigger battle that he would have preferred.
Scott made a 7-foot par putt on the final hole for a 1-under 71, giving him a three-shot lead over Keegan Bradley going into Sunday.
"I've got to go out and try to win the tournament (Sunday)," said Scott, who was at 15-under 201 said. "I'm not trying to win the No. 1 ranking. I've got a bunch of guys breathing down my neck who all have had nice rounds today and are feeling pretty good about the way they're playing. ... So I'm going to have to play a pretty sharp round of golf and not open the door at all."
Bradley birdied his last three holes, taking on the flag at the 18th with a 9-iron from 167 yards that narrowly cleared the rocks framing the lake and settled 4 feet from the flag. That was the final touch on an eight-birdie round of 66.
"I just kind of like that underdog role," Bradley said. "I like knowing I've got to go out there and play well."
Matt Every (66) and Jason Kokrak (67) were four shots back, both with a chance to win on the PGA Tour for the first time.
Tiger Woods, the two-time defending champion at Bay Hill and No. 1 in the world, withdrew before the tournament because of recurring back pain. Scott has a chance to replace him at No. 1 in the world with a win, though he wouldn't take over at the top until the week before the Masters.
"When you've got the lead, you have to work for it," Scott said. "I'm still in good shape."
LPGA: Lydia Ko topped the JTBC Founders Cup leader board, pulling ahead with two late birdies in Phoenix. The 16-year-old shot a 5-under 67 to reach 16-under 200 at Desert Ridge. She tapped in for birdie on the par-5 15th after missing an 8-foot eagle putt and made a 10-foot birdie putt on the par-3 17th. Jessica Korda (66) and Mirim Lee (70) were a stroke back, and a dozen players were within four shots.
Champions: Billy Andrade shot a 7-under 65 to share the lead with Fred Funk after the second round of the Mississippi Gulf Resort Classic at Fallen Oak. Andrade capped his day with a 20-foot birdie putt on 18 for an 8-under 136. Funk shot a 67. Andrade, 50, is playing in just his fourth tour event. First-round leader Fred Couples (71), Jay Haas (69) and Jeff Maggert (69) were at 137.
