GULLANE, Scotland -- A birdie at the par-5 ninth hole has moved Phil Mickelson into a tie for second with Ian Poulter and Henrik Stenson at even par.
Mickelson, who has two top-10s in 19 appearances at The Open Championship, played the front nine at Muirfield in 2 under. Mickelson won the Aberdeen Asset Management Scottish Open last Sunday to notch his only victory in the UK.
Lee Westwood still leads and his advantage is now three after he made a 20-footer for birdie at the fifth hole. He is 3 under and the only player in red numbers now on the leaderboard.
Tiger Woods, who started the day tied for second with Hunter Mahan, has made three bogeys in his first six holes to fall five behind Westwood. Ditto for Mahan, who is playing in the final group with Westwood.
