AKRON, Ohio — Bubba Watson sure didn't look as though he was making his debut at Firestone. He opened with a 6-under 64 to build a two-shot lead after one round of the Bridgestone Invitational.

Seven-time champion Tiger Woods looked as if he had never been here before. Woods got off to an atrocious start Thursday on his way to a 4-over 74, his highest round ever at Firestone. It also ended his streak of nine rounds at par or better on the tree-lined course.

Watson, who won the Travelers Championship in June for his first tour victory, is trying to play his way onto the Ryder Cup team. He was two shots clear of Phil Mickelson, Kenny Perry and Adam Scott.
