KEY POINTS:
American golfers Fred Couples and JJ Henry shared the lead with rounds of five under 65 after the first round at the Arnold Palmer Invitational yesterday.
World No 1 Tiger Woods, chasing his ninth win in 10 tournaments and a four-times winner here, ended his round on par 70 after two birdies and two bogeys.
Couples, appointed US captain for the 2009 Presidents Cup last month, produced six birdies but dropped a shot at the difficult par-three 17th hole.
