Sung Ah Yim picked up her first LPGA Tour victory in the most unlikely way possible: a final-round collapse by Annika Sorenstam that allowed the 22-year-old South Korean to win by two strokes yesterday at Stockbridge, Ga.

After three straight rounds in the 60s gave Sorenstam the lead going into the final day of the Florida's Natural Charity Championship, she slumped to a 3-over 75 that left her in a three-way tie for second with Karrie Webb and Cristie Kerr.

Tied for the lead going to the next-to-last hole, Sorenstam knocked her tee shot out of bounds and took double bogey.

"It was not a very good day for me," Sorenstam said. "I didn't play well at all. I just want to forget about this day as quickly as possible."

Yim, in just her second year on the tour, played in the final group with Sorenstam. Amazingly, the part-time university student was the one who held it together at the end, scrambling for a 72 that was good enough to win. She got up and down from the fringe on three straight holes before knocking in a short birdie putt at the par-5 18th to finish at 16-under 272.

"I've never had that much concentration," Yim said. "I could hear my heart beating."

Sorenstam was seeking her second straight win at Eagle's Landing Country Club near Atlanta and the 68th LPGA Tour victory of her Hall of Fame career. She had won 11 straight events with a lead going to the final round — a streak that dated to the 2004 Evian Masters.

APPLEBY VICTORIOUS

Stuart Appleby shot a 5-under 67 to cap a wire-to-wire victory in the Shell Houston Open and join Tiger Woods and Phil Mickelson as the only two-time winners on the PGA Tour this year.

Appleby, also the 1999 winner in Houston, finished at 19-under 269 on the new Tournament Course at Redstone, in Humble, Texas, six shots ahead of Bob Estes. Appleby matched the tournament record for margin of victory and was the first player in the event's 60-year history to lead from the opening round to the end.

Appleby, who turns 35 on May 1, earned $990,000 for his eighth tour win and has two victories in the same year for the first time in his career. In January, Appleby won the season-opening Mercedes Championships in Hawai'i for the third straight time.

CHAMPIONS TOUR

HAAS EARNS CROWN

Jay Haas had an eagle and three birdies on the back nine to pull away from Peter Jacobsen and Craig Stadler in the Liberty Mutual Legends of Golf at Savannah, Ga.

Haas, the Champions Tour rookie of the year in 2005, shot a 5-under 67 for a three-round total of 15-under 201 at The Club at Savannah Harbor. Jacobsen (67) and Stadler (70) tied for second at 10 under, and Hale Irwin (68) was another stroke back.

Haas, who missed the cut last week in the PGA Tour's Verizon Heritage in nearby Hilton Head, S.C., led all three days in the 54-hole event.
