ATLANTA — Four days after Anthony Kim humbled Sergio Garcia in the Ryder Cup, he beat 29 players just as badly Thursday at the Tour Championship.

Showing no effects of a Ryder Cup hangover, Kim fired off eight birdies on his way to a 6-under 64 in his Tour Championship debut to build a four-shot lead over Masters champion Trevor Immelman, Ernie Els and Phil Mickelson.

Kim and the other nine Americans from the winning team rarely got through a hole without hearing someone in the gallery congratulate them on their 16 1/2-11 1/2 victory over Europe on Sunday. Kim was smiling just as wide as he did Thursday.

"I feel like when I'm happy, having a good time, I'm going to make some birdies," he said. "So it was a good vibe out there."

Vijay Singh wasn't feeling it.

He only has to complete all four rounds at East Lake to capture the FedEx Cup, and that might have been the best part of his opening round at East Lake — he finished. But he started poorly, 5 over through 11 holes, before settling for a 73.

Kenny Perry, the Kentucky hero from the Ryder Cup, also found little reason to smile. He opened with a 76.

Good thing the 23-year-old Kim had four days to try to get the Ryder Cup out of his system. He was the life of the party Sunday night, especially after his 5-and-4 victory over Garcia in which Kim made birdie or better on six of his 14 holes.

"Just trying to enjoy the moment," he said. "This Ryder Cup hangover doesn't feel as bad as a college hangover."

NAVISTAR LPGA CLASSIC: At Prattville, Ala., Jill McGill, Jane Park and Jeong Jang shot 7-under 65s for a share of the Navistar LPGA Classic lead, while top-ranked Lorena Ochoa was two strokes back in her first event in a month.

Ochoa played her first competitive round since tying for sixth in the Safeway Classic on Aug. 24, her fourth top-seven finish in a row, but seventh straight winless start. She opened the year with six victories in nine starts, including four straight.

Safeway winner Cristie Kerr and Janice Moodie opened with 66s on the links-style Senator Course at the Robert Trent Jones Golf Trail's Capitol Hill complex. Sandra Gal, Katie Futcher, Ji Young Oh and Louise Friberg matched Ochoa with 67s.

BRITISH MASTERS: At Sutton Coldfield, England, Australia's Marcus Fraser and Sweden's Mikael Lundberg shot 5-under 67s to share the first-round lead in the British Masters.

Defending champion Lee Westwood, the English star coming off Europe's Ryder Cup loss, was a stroke back along with countryman Sam Walker, Scotland's Marc Warren, Denmark's Anders Hansen and Argentina's Rafa Echenique.

USGA SENIOR AMATEUR: At Fort Worth, Texas, U.S. Walker Cup captain Buddy Marucci won the USGA Senior Amateur, beating George Zahringer 2-up at Shady Oaks Country Club.

The 56-year-old Marucci, from Villanova, Pa., won for the first time in 51 starts in USGA events. He lost to Tiger Woods in the 1995 U.S. Amateur final.

Marucci, the captain of the victorious 2007 Walker Cup team in Northern Ireland, will be unable to defend his title next year at The Beverly Club in Chicago. He will instead be at Merion as the returning captain of the 2009 Walker Cup squad.

Zahringer was 3-down through 12 holes, but the 55-year-old New Yorker rallied to cut the deficit to one with a par on the par-5 15th. They halved the 16th and 17th with pars and Marucci won with a par on 18.

USGA SENIOR WOMEN'S AMATEUR: At Tulsa, Okla., Diane Lang won the USGA Senior Women's Amateur for the third time in four years, beating Toni Wiesner 6 and 5 at Tulsa Country Club.

The 53-year-old Lang, a Jamaican who lives in Weston, Fla., also won the 2005 and 2006 tournaments. The sixth player to win the event three or more times, she also was a semifinalist in 2007, making her 22-1 in four years in the event.

The 61-year-old Wiesner, from Fort Worth, was trying to become the first left-handed female USGA champion. She also lost the 1997 and 2000 finals.
