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.
The Open Championship: Earned 10th professional major title at The Open Championship at age 29 years, 6 months and 17 days in his 35th major as a professional. Posted rounds of 66-67-71-70–274 at St. Andrews to defeat nearest challenger Colin Montgomerie by five strokes. The youngest and quickest to win each of the four major championships twice. Jack Nicklaus was the first to accomplish the feat at 31 years, 1 month and 7 days when he won his second PGA in 1971 in his 37th major as a professional. Sixth player in The Open Championship history to win in wire-to-wire fashion–Ted Ray (1912), Bobby Jones (1927), Gene Sarazen (1932), Henry Cotton (1934) and Tom Weiskopf (1973).
Farmers Insurance Open: In his season debut on the PGA TOUR, became the first player in TOUR history to win on the same course eight times with his Farmers Insurance Open victory at Torrey Pines GC. The win marked the sixth time on TOUR he has won in his season debut. His seventh Farmers Insurance Open win came five years after his U.S. Open win at Torrey Pines. At 14-under 274, won by four strokes over defending champion Brandt Snedeker and Josh Teater. He converted the 54-hole lead into victory for the 50th (of 54) time. With the win, the Farmers Insurance Open became the third event in which he has won seven times, the World Golf Championships-Bridgestone Invitational and Arnold Palmer Invitational being the others. In the previous six years he has won this event, he has gone on to win at least four times in each of those years. His 75th TOUR victory is just seven shy of the all-time record of 82, held by Sam Snead.
Woods collaborated closely with TAG Heuer to develop the world's first professional golf watch, which was released in April 2005. 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. In 2006, the TAG Heuer Professional Golf Watch won the prestigious iF product design award in the Leisure/Lifestyle category.
