On a tightly packed leader-board, Fredrik Jacobson is 4-under 67, and six players -- including Tom Lehman and David Toms -- finished 3-under 68. Nine players -- including Mike Weir, Brandt Jobe and Paul Azinger -- shot 2-under 69, and 14 others are 1-under 70.
Defending champion Padraig Harrington opened with a 3-over 74.
Harrington beat Jim Furyk in a playoff in 2005 with a 65-foot eagle putt at the 18th hole.
