PRATTVILLE, Ala. (AP) - At 16, Lexi Thompson has become the youngest player to win an LPGA Tour event.
The Floridian closed with a 2-under 70 on Sunday to win by five strokes at the Navistar LPGA Classic over Tiffany Joh.
Thompson shattered the age record for winning a multiple-round tournament held by Paula Creamer, who won in 2005 at 18. Marlene Hagge was 18 years and 14 days old when she won the single-round Sarasota Open in 1952.
Thompson, who turned 16 in February, led by five strokes entering the final round and built that to seven through 10 holes at the Robert Trent Jones Trail's Capitol Hill complex. Then came the teen's only big lapse on the pressure-packed day when she bogeyed the next two holes while Joh surged to within three strokes.
Thompson erased any concerns of a collapse with birdies on Nos. 16 and 17.
BMW Championship
LEMONT, Ill. (AP) - Justin Rose chipped in for birdie on the 17th hole and hung on to win the BMW Championship.
Rose closed with an even-par 71 at Cog Hill for a two-shot victory and is headed to the Tour Championship with a shot at the $10 million FedEx Cup prize. But it wasn't that easy. He watched a five-shot lead shrink to one shot over John Senden until the birdie chip gave him a cushion.
Senden closed with a 70 to finish alone in second and go from No. 55 in the FedEx Cup to No. 9, making him among the top 30 who qualify for the Tour Championship.
Geoff Ogilvy (69) finished third. That gave him a spot at East Lake and at Royal Melbourne for the Presidents Cup.
Songdo IBD Championship
INCHEON, South Korea (AP) - Jay Don Blake beat John Cook on the fifth playoff hole for his first Champions Tour victory.
The two Americans shot 68s in the final round to finish at 13-under 203 with Mark O'Meara and Peter Senior at the Jack Nicklaus Golf Club Korea. O'Meara and Senior were eliminated from the playoff after bogeys on the third hole. Blake won with a 10-foot birdie on the fifth.
In April, Cook beat Blake in a playoff in Lutz, Fla.
Blake had a chance to win on the 18th hole in regulation but missed a 15-footer for birdie. Senior closed with a 64 to reach the playoff while O'Meara had a 67. Second-round leader Michael Allen shot a 75 and finished at 209.
Albertsons Boise Open
BOISE, Idaho (AP) - Rookie Jason Kokrak earned his first career Nationwide Victory, making the most of being the last player to get into the Boise Open.
The 26-year old from Charlotte, N.C., started the final round at the Hillcrest Country Club tied for the lead and shot a bogey-free, 4-under 67 to beat John Mallinger by two strokes.
Kokrak finished at 18-under 266 to become the Nationwide Tour's 10th first-time winner and fourth rookie winner in 2011 after getting the call Tuesday that he was in the field.
The winner's check for $130,000 moved him to No. 13 on the money list from No. 70.
The 25 leading money winners will earn PGA Tour cards for 2012. There are five full-field events left before the season-ending Tour Championship.
