NORTON, Mass. -- Jason Day capped off an exciting day with a routine birdie to take the lead Sunday in the Deutsche Bank Championship, setting up a Labor Day finish with all sorts of possibilities.
Day watched a three-shot lead evaporate in two holes, only to get it back on the par-5 18th with a shot just off the back of the green, leaving him a simple two-putt for birdie and a 5-under 66. He had a one-shot lead over Brandt Snedeker, who made a mess of the 18th until chipping in for par and a 67.
Just like so many other times at this tournament, the Deutsche Bank Championship could be up for grabs.
And so could the No. 1 ranking.
Tiger Woods could only manage one birdie over the last 11 holes and shot a 2-under 69, leaving him tied for 23rd and 10 shots out of the lead. That set the stage for Phil Mickelson or Steve Stricker to end his five-year run atop the world ranking.
Stricker is closer to the lead. Mickelson has better odds.
Both of them might have a tough time catching up to Day, the 22-year-old Australian who won the Byron Nelson Championship in May and is starting to play his best golf during the FedEx Cup playoffs.
Day was at 17-under 196, matching the 54-hole record at the TPC Boston set by Mike Weir two years ago.
Luke Donald, winless on the PGA Tour in more than four years, was steady again in his first tournament since being picked for Europe's Ryder Cup team. He birdied the last hole for a 66 and was two shots behind.
Defending champion Stricker played his third straight round without a bogey for a 67 and was at 13-under 200 with Charley Hoffman, who had a 69.
Mickelson was in a group at 201 that included Geoff Ogilvy (65), who hasn't finished in the top 10 since winning the season-opening SBS Championship; and Adam Scott (65), who won the Deutsche Bank Championship in 2003.
Snedeker was three shots behind going to the 16th tee when he made consecutive birdies -- Day three-putted the 16th -- to share the lead. But the final hole -- the easiest at the TPC Boston with a tail wind -- nearly got him. He didn't hit enough club and went into the hazard, and after taking a penalty drop, his fourth shot barely cleared the hazard and stayed in the rough.
NATIONWIDE TOUR: Former Georgia player Kevin Kisner won the inaugural Mylan Classic for his first Nationwide Tour title, closing with a bogey-free 4-under 67 on Sunday for a one-stroke victory over Geoffrey Sisk.
Kisner finished at 13-under 271 at Southpointe Golf Club and earned $108,000 to jump from 50th to 14th on the money list with $194,692. The final top 25 on the list will earn 2011 season PGA Tour cards.
"This game is so much about winning and you have to beat 155 great players in order to have a chance," Kisner said. "This is pretty special."
Kisner closed with a 4-foot par putt, but didn't know that Sisk (71) had fallen behind with a double bogey on the 17th. The 45-year-old Sisk then failed to birdie the 72nd hole, giving Kisner the title.
"I didn't know I was going to win even when I made that last putt," Kisner said. "I was kind of in shock. I thought I might have been one short or maybe could get into a playoff. My whole world turned upside down there in a minute."
Kisner hit 15 of 18 greens in regulation.
"I played solid all day. I made a lot of the 4- and 5-footers that you need to make," Kisner said. "I just stayed in my own game. I was as calm as I've ever been in that situation, which is odd considering this was probably the biggest stage I've ever been on. I didn't look at a board all day."
CHAMPIONS TOUR: Ted Schulz won the First Tee Open for his first Champions Tour title, holing a 12-foot birdie putt on the 17th hole at Pebble Beach en route to a 2-under 70 and a one-stroke victory over Tom Pernice Jr.
The 50-year-old Schulz -- in the field on conditional status in his 12th start on the 50-and-over tour -- finished at 14-under 202. It was his first victory since winning the 1991 Nissan Open for the second of his two PGA Tour titles.
Pernice finished with a 67. Mark Calcavecchia and Tom Kite closed with 69s to tie for third at 12 under. Fred Couples (68) followed at 11 under.
EUROPEAN MASTERS: Spain's Miguel Angel Jimenez won the European Masters for his third victory of the year, shooting a 4-under 67 to beat Italy's Edoardo Molinari by three strokes.
The 46-year-old Jimenez finished at 21-under 263. He also won this year in Dubai and France and has 18 career PGA European Tour titles, 11 since turning 40. Molinari, the Johnnie Walker winner the previous week in Scotland, also shot a 67.
