After a slow start to 2014, Woods sustained an injury during the final round of the Honda Classic and was unable to finish the tournament. He withdrew after the 13th hole, citing back pain. He subsequently competed in the WGC-Cadillac Championship but was visibly in pain during much of the last round. He was forced to skip the Arnold Palmer Invitational at the end of March 2014, and after undergoing back surgery, he announced on April 1 that he would miss the Masters for the first time since 1994. Woods returned at the Quicken Loans National in June, however he stated that his expectations for the week were low. He would struggle with nearly every aspect of his game and miss the cut. He next played at The Open Championship, contested at Hoylake, where Woods had won eight years prior. Woods fired a brilliant 69 in the first round to put himself in contention, but shot 77 on Friday and would eventually finish 69th. Despite his back pain, he played at the 2014 PGA Championship where he failed to make the cut. On August 25, 2014, Woods and his swing coach Sean Foley parted ways. In the four years under Foley, he won eight times but no majors. He had previously won eight majors with Harmon and six with Haney. Woods said there is currently no timetable to find a replacement swing coach.
Set or tied 27 TOUR records. Won three consecutive majors (U.S. and The Open Championships, PGA Championship) and career Grand Slam and totaled nine TOUR victories. Non-adjusted scoring average of 68.17 best in golf history, surpassing Byron Nelson's 68.33 unofficial mark of 1945. Finished the year with 47 consecutive rounds of par or better and completing all 20 events started under par. Won TOUR player of the year honors. Joined Ben Hogan (1953) as the only men to win three professional majors in one season. Was 53-under in four majors, next-best mark was 18-under by Ernie Els. Nine TOUR victories most in one season since Sam Snead won 11 in 1950. Season-opening victories at Mercedes Championship and AT&T Pebble Beach National Pro-Am gave him wins in six consecutive starts, most since Hogan in 1948. Beat Els in a playoff at Mercedes, then came from seven strokes back with seven holes to play at Pebble Beach, keyed by an eagle-birdie-par-birdie finish, for a 64 and a two-stroke win. Finished T2 at Buick Invitational.
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, 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. Over the next few days, more than a dozen women claimed in various media outlets to have had affairs with Woods. 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."
Difficult season off the course, as he suffered the loss of father Earl after a long battle with cancer on May 3. Inside the ropes, World No. 1 dominated with eight victories, including two major titles (The Open Championship and PGA Championship). Entered the 2007 season with a TOUR streak of six consecutive victories. Led the TOUR in scoring average (68.11) but not eligible for seventh Vardon Trophy as he did not play 60 competitive rounds. Won Byron Nelson Award for low scoring average.
PGA Championship: Won 12th major at the PGA Championship at Medinah CC, moving into solo second behind Jack Nicklaus (18) on the career majors list. First player to win two PGAs at the same course (1999 and 2006). Recorded four rounds in the 60s (69-68-65-68) for just the second time in a major (2000 Open Championship). Tied the tournament record which he set with Bob May in 2000 (18-under 270). Became the 29th player in major championship history to collect two major wins in the same year, this being his fourth time.
Deutsche Bank Championship: Shot a final-round 63 to equal lowest final round of his TOUR career at Deutsche Bank Championship. Course-record equaling front-nine 30 included a holed 9-iron at the par-4 6th hole for eagle. The T11 finish represented the third time in 2009 he finished outside the top-10 (T17 at Accenture Match Play and missed cut at The Open Championship).
World Golf Championships-Accenture Match Play Championship: Captured second consecutive World Golf Championships-Accenture Match Play Championship for 40th career PGA TOUR win. With six match victories, including a 3-and-2 win over Davis Love III in the 36-hole finale, has won 12 consecutive matches, and overall Accenture Match Play Championship record is 20-3.
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.
