World Golf Championships-Bridgestone Invitational: Benefactor of a big change in momentum on Firestone CC's famous 16th hole in winning for the 70th time in his career with the World Golf Championships-Bridgestone Invitational victory. Trailing by one stroke, hit an 8-iron from 178 yards to within tap-in range for a birdie on the long par-5 16th. Meanwhile, Padraig Harrington, the third-round leader, hit from the collar of a bunker over the 16th green, but his delicate flop shot from behind the green came out hot, went into the water and he made a triple bogey-8 to give up the lead. Closed with consecutive 5-under 65s to reach 12-under and win by four strokes over Harrington and Robert Allenby. Became the first player in TOUR history to win the same event seven times on the same golf course. Also picked up 550 FedExCup points and extended his lead to 946 points. Joined Sam Snead (82) and Jack Nicklaus (73) as the only players to win 70 career TOUR events, but did so nearly seven years younger than Snead or Nicklaus.
Ford Championship at Doral: Took over as World No. 1 for the first time since the week of Aug. 30, 2004 by defeating Phil Mickelson by a stroke at the Ford Championship at Doral. Paired with Mickelson in the final round for just the third time in his career, began the day two strokes behind. Caught up to Mickelson at the turn and took a two-stroke lead after an eagle on the par-5 12th hole. Mickelson birdied the next two and both bogeyed the 16th to remain tied with two holes to play. Birdied the 17th hole and when Mickelson's chip on No. 18 lipped out, earned the 42nd victory of his career.
In 2011, Woods' performance continued to suffer; this took its toll on his ranking. After falling to No. 7 in March, he rebounded to No. 5 with a strong showing at the 2011 Masters, where he tied for fourth place. Due to leg injuries incurred at the Masters, he missed several summer stops on the PGA Tour. In July, he fired his longtime caddy Steve Williams (who was shocked by the dismissal), and replaced him on an interim basis with friend Bryon Bell until he hired Joe LaCava. After returning to tournament play in August, Woods continued to falter, and his ranking gradually fell to a low of #58. He rose to No. 50 in mid-November after a third-place finish at the Emirates Australian Open, and broke his winless streak with a victory at December's Chevron World Challenge.
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.
Won seven times en route to capturing the inaugural FedExCup, cruising through the PGA TOUR Playoffs for the FedExCup with two wins and a T2 in three starts. Captured 13th career major championship (second all-time to Jack Nicklaus' 18) and finished the year with 61 official PGA TOUR victories, fifth all-time. Adjusted scoring average was 67.79, matching own record set in 2000. With 60 official rounds, won his seventh career Vardon Trophy and also captured the Byron Nelson Award.
