Couples, Henry lead at Bay Hill

ORLANDO, Fla. -- Fred Couples made four birdies in his opening six holes, shot 5-under 65, and golf finally felt fun. Tiger Woods couldn't hit the green with a wedge, struggled to shoot even par, and he finally looked human.

The Arnold Palmer Invitational delivered a few surprises Thursday, none bigger than the 48-year-old Couples booming tee shots, taking only 23 putts and finishing atop the leaderboard with J.J. Henry.

In three previous trips to Bay Hill, Henry had never done better than 71. He played under warm sunshine without a bogey, making four birdie putts outside 15 feet.

Couples and Henry were a stroke ahead of defending champion Vijay Singh, Lee Westwood, Tom Lehman and Lucas Glover.

Woods, who has won every tournament he has played since September, opened with a 70 that left him five shots behind.
