HARRISON, N.Y. – Dr. Snowball might be making house calls next week at Shinnecock Hills if Fred Couples keeps playing like this.

After night and morning acupuncture sessions with Halina Snowball in Greenwich, Conn., the 44-year-old Couples shot a bogey-free 6-under 65 on Friday to take the second-round lead in the Buick Classic.

“As soon as I left her office yesterday, I didn’t have any pain in my back,” Couples said. “I don’t get it, but I’m going to keep trying it. To me, it’s unbelievable what they can do.”

Coming off a second-place finish last week in the Memorial, Couples birdied the final two holes on the Westchester Country Club course to take a one-stroke lead over Vijay Singh, Fredrik Jacobson and young playing partner Luke Donald.

“I’ve kept the ball in play, which is the key here,” said Couples, who played with acupuncture pins in his ears.

Couples’ wife, Thais, tried to talk him into withdrawing Wednesday night to rest his back for the U.S. Open next week at Shinnecock Hills.

“I snuck out of there Thursday when she was still sleeping,” Couples said. “She’s downtown with the kids now. She’ll come home and I’ll tell her I’m leading the tournament and she’s going to have a heart attack.”

Couples took advantage of Jacobson’s double-bogey 7 on the par-5 ninth – his last hole – to top the leaderboard at 10 under.

Jacobson’s tee shot struck a tree and bounced away from the tree line, but he failed to take advantage of the break when his 8-iron third shot went into the thick rough to the right of the green. After lobbing his fourth shot into an awkward position in the left fringe, he chipped 5 feet past the hole and missed the bogey putt.

“It could have been a 9,” the Swede said.

He finished with a 69, Donald had a 66 and Singh followed his opening 63 with a 70.

“I had a lot of half-shots today,” said Singh, the 1993 and 1995 winner. “If you’re between clubs, it’s very hard to get close.”

Jacobson, a stroke behind Singh after a first-round 64, holed out from 112 yards for eagle on the par-4 second hole to tie Singh for the lead at 9 under. The Swede reached 10 under with an 8-foot birdie putt on the par-5 fifth, and took a two-stroke lead with a 15-footer on the par-3 sixth.

Tom Byrum eagled the 18th for a 64 – the best round of the day – to finish at 7 under, and Padraig Harrington shot his second straight 68 to join Billy Mayfair, Scott Hend, Tjaart Van der Walt and Cameron Beckman at 6 under. Van der Walt, the last player to get into the field, had a 65, and Mayfair, Hend and Beckman shot 68s.

Masters champion Phil Mickelson and two-time Buick Classic winner Ernie Els were 5 under.

Bean, Harris, Doyle share lead at Bayer Advantage

PARKVILLE, Mo. – Andy Bean, John Harris and Allen Doyle tied the course record with 7-under-par 65s Friday and shared the first-round lead at the Bayer Advantage Celebrity Pro-Am.

Mark James and Morris Hatalsky were a shot back at 6 under, and six players were tied at 5 under. Twenty players are within four shots of the lead at the National Golf Club of Kansas City.

Bean was back in contention one week after being forced to withdraw from the final round of the Farmers Charity Classic due to an allergic reaction to food he had for breakfast. Tied for the lead heading into the final round, Bean passed out in the caddie tent and could not tee off, missing out on the chance for his first victory since the 1986 Byron Nelson Classic.

“I won’t be having English muffins and sausage for breakfast,” Bean joked Friday.

Bean opened with five birdies on his first six holes and made the turn at 30 after seven birdies, a par and a bogey. He made three more birdies on the back nine, including the 18th after hitting his approach to 5 feet. He gave two strokes back with a double-bogey at the par-3 16th.

Course designer and Kansas City native Tom Watson was nine strokes behind the leaders after an opening 2-over 74.

LPGA washed out, setting up 36-hole Sunday finish

WILMINGTON, Del. – Jennifer Rosales wanted to build on her one-shot lead Friday in the LPGA Championship. Instead, she did her laundry.

Steady, overnight rain filled bunkers with water and left DuPont Country Club so saturated that the maintenance crew couldn’t even mow the fairways and greens. With more rain in the forecast and 144 women in the field, tournament officials decided to take the day off.

Rosales, who opened with a 5-under 66, showed up at the course and noticed no one was on the practice range. She learned of the delay and headed back to her room.

“I just did my laundry,” she said in a telephone interviews. “I’m going to have lunch and watch a movie.”

She has a one-shot lead over Karen Stupples, Gloria Park and Chiharu Yamaguchi.

Sorenstam and Grace Park were among those at 68.
