Bay Hill was so penal on Friday that most players figured it would be difficult for anyone to shoot a low number and separate themselves from the pack. Sean O'Hair apparently didn't get the memo.

O'Hair opened with three straight birdies and didn't drop a shot
until his final hole, which gave him a 5-under 65 for a three-shot
lead over Jason Gore heading into the weekend at the Arnold Palmer
Invitational.

Tiger Woods remained in the mix for a sixth title at Bay Hill, courtesy of a short game turned a mediocre round into a 69.

Woods chipped in for birdie on his opening hole for the second
straight day, holed another birdie chip on No. 8, and kept his round together with two head-turning chips to save par. He was in
fifth place, five shots behind.
