Masters Tournament: Claimed fourth Masters title at age 29 years, 3 months and 10 days with sudden-death playoff victory over Chris DiMarco. Tied Arnold Palmer for second-most Masters victories, with four, two behind Jack Nicklaus. Recovered from a first-round 2-over-par 74 and took the 54-hole lead by three over DiMarco with rounds of 66-65. During that stretch of the third round, posted seven straight birdies (Nos. 7-13), matching Steve Pate's 1999 record birdie streak at Augusta National. Final round included chip-in on par-3 16th hole from behind the green that extended lead to two strokes and bogeys on two closing holes for a 1-under-par 71, tied with DiMarco at 12-under-par 276 total. Rolled in 15-foot birdie putt on first playoff hole to earn green jacket and re-claim the No. 1 position in the Official World Golf Ranking.
the Memorial Tournament presented by Nationwide Insurance: Moved into a tie with Jack Nicklaus for second on the all-time PGA TOUR victories list, with 73, after his two-shot victory at the Memorial Tournament. Trails only Sam Snead's 82 wins after a two-shot victory over Andres Romero and Rory Sabbatini at Muirfield Village GC. Posted his 73rd career victory at age 36 years, 5 months, 4 days, nearly 10 years younger than Nicklaus when he won his 73rd tournament (46 years, 2 months, 23 days) and almost seven years younger than Snead when he posted his 73rd victory (43 years, 9 days). Collected his fifth career victory at the Memorial Tournament and won in come-from-behind fashion for the 21st time in his career after entering the final round four shots off the 54-hole pace. Trailed Sabbatini by two shots standing on the 15th tee but played his final four holes in 3-under, making birdie on Nos. 15, 16 and 18. Holed a flop shot from 49 feet, 10 inches from behind the green at the par-3 16th to tie Sabbatini for the lead at 8-under. Won the Arnold Palmer Invitational and the Memorial Tournament in the same year for the fourth time (2000-01, 2009 and 2012). Posted the 12th victory of his career in Ohio and won multiple tournaments in a season for the 13th time in his career.
Buick Open: Shot a final-round 69 and coasted to a three-shot victory with a 20-under 268 at the Buick Open for the 69th PGA TOUR title of his career. Improved to 36-1 when he had the outright lead after 54 holes. The win was his fourth of the season in just 11 starts since returning from knee surgery and the 69th of his career. He also claimed 500 FedExCup points and moved to the top of the standings. Reached victory No. 69 at the age of 33 years and seven months–almost seven years faster than Jack Nicklaus and eight years sooner than Sam Snead. Shot a 71 in the first round and came back with the best five-hole start of his career–beginning 6-under in the second round–en route to a 9-under 63 for his best score in relation to par in four years. Shot a 65 in the third round and held a one-shot lead going into Sunday.

On December 2, following Us Weekly's previous day reporting of a purported mistress and subsequent release of a voicemail message allegedly left by Woods for the woman,[216] Woods released a further statement. He admitted transgressions and apologized to "all of those who have supported [him] over the years", while reiterating his and his family's right to privacy.[211][217] Over the next few days, more than a dozen women claimed in various media outlets to have had affairs with Woods.[6] On December 11, he released a third statement admitting to infidelity and he apologized again. He also announced that he would be taking "an indefinite break from professional golf."[6]
Woods collaborated closely with TAG Heuer to develop the world's first professional golf watch, which was released in April 2005.[139] The lightweight, titanium-construction watch, designed to be worn while playing the game, incorporates numerous innovative design features to accommodate golf play. It is capable of absorbing up to 5,000 Gs of shock, far in excess of the forces generated by a normal golf swing.[139] In 2006, the TAG Heuer Professional Golf Watch won the prestigious iF product design award in the Leisure/Lifestyle category.[140]
