Buick Open: Second-round, 9-under-par 63 led to a win at the Buick Open, his 33rd career title and 20th different tournament triumph. Led after both 36 and 54 holes. Has won 25 of 27 events when he was the 54-hole leader/co-leader. Entered the final round one stroke ahead of Esteban Toledo. Carded a 2-under 70 to secure a four-stroke victory over four players.
From mid-1993 (while he was still an amateur) until 2004, Woods worked almost exclusively with leading swing coach Butch Harmon. From mid-1997, Harmon and Woods fashioned a major redevelopment of Woods' full swing, achieving greater consistency, better distance control, and better kinesiology. The changes began to pay off in 1999. Woods and Harmon eventually parted ways. From March 2004 to 2010, Woods was coached by Hank Haney, who worked on flattening his swing plane. Woods continued to win tournaments with Haney, but his driving accuracy dropped significantly. Haney resigned under questionable circumstances in May 2010 and was replaced by Sean Foley.
THE PLAYERS Championship: Withdrew on the seventh hole in the final round of THE PLAYERS Championship with a lingering neck injury that caused tingling in the fingers in his right hand. Shot 70-71-71 in first three rounds. It was the third time he has withdrawn from a TOUR event as a professional (2006 Northern Trust Open, 1998 AT&T Pebble Beach National Pro-Am). Also withdrew from the 1995 U.S. Open as an amateur.
