In the days and months following Woods' admission of multiple infidelities, several companies re-evaluated their relationships with him. Accenture, AT&T, Gatorade and General Motors completely ended their sponsorship deals, while Gillette suspended advertising featuring Woods. TAG Heuer dropped Woods from advertising in December 2009 and officially ended their deal when his contract expired in August 2011. Golf Digest suspended Woods's monthly column beginning with the February 2010 issue. In contrast, Nike continued to support Woods, as did Electronic Arts, which was working with Woods on the game Tiger Woods PGA Tour Online. A December 2009 study estimated the shareholder loss caused by Woods's affairs to be between $5 billion and $12 billion.
U.S. Open Championship: In his first start two months after surgery, parred the first sudden-death hole to beat Rocco Mediate and win the U.S. Open at Torrey Pines GC. Prevailed after he birdied the par-5 18th hole on Monday afternoon to complete an even-par 71 in an 18-hole playoff and tie Mediate to force sudden death, beginning on the par-4 seventh hole. Hit the green in regulation and two-putted on the dogleg right while Mediate, who was aiming to become the oldest U.S. Open champion at age 45, drove into a fairway bunker and then missed a 20-foot par putt. Sank a 12-foot birdie putt on the 72nd hole to force the 18-hole playoff with Mediate at 1-under-par 283. The victory was his third in the U.S. Open, his 14th major championship and the 65th of his TOUR career, third alone behind Sam Snead (82) and Jack Nicklaus (73). Improved to 14-for-14 in majors when holding the third-round lead. The win was also his seventh at Torrey Pines in La Jolla, Calif. (six Buick Invitationals and one U.S. Open), the most in TOUR history on one course.
Earned his 80th PGA TOUR victory and first since 2013, winning the TOUR Championship for the third time in his career to move within two of Sam Snead's TOUR-best 82 victories. Finished the season No. 2 in the FedExCup, with runner-up finishes at the Valspar Championship and PGA Championship among his seven top-10s. Led the TOUR in Strokes Gained: Approach the Green (0.938) for the sixth consecutive season in which he played the minimum number of rounds. After originally being selected as a Captain's Assistant for the United States Ryder Cup team, was later selected as a captain's pick and played in the event for the eighth time.
The Open Championship: Finished T6 at the 147 Open Championship at Carnoustie, his first top-10 in a major since at T6 at the 2013 Open Championship. Week was highlighted by a third-round 66, his lowest round in a major since a 66 in the second round of the 2011 Masters. Was just his second made cut (2018 Masters Tournament/T32) in his last six major starts. Posted rounds of 71-71-66-71, the first time since the 2010 Masters Tournament (T4) he recorded four par-or-better rounds in a major. Paired with eventual-champion Francesco Molinari, entered the final round four shots off the lead. Took the solo-lead at 7-under after nine holes, one ahead of Molinari and Jordan Spieth, but his lead disappeared with a double bogey at No. 11. Bogeyed No. 12 and birdied No. 14 before closing with four pars to finish at 5-under. The finish moved him to No. 50 in the Official World Golf Ranking, returning to the top 50 for the first time since January 2015. The ranking also earned him a spot in the World Golf Championships-Bridgestone Invitational.
