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).
On February 5, 2015, Woods withdrew from the Farmers Insurance Open after another back injury.[102] Woods stated on his website that it was unrelated to his previous surgery and he would take a break from golf until his back healed.[103] He returned for the Masters, finishing in a tie for 17th. In the final round, Woods injured his wrist after his club hit a tree root. He later stated that a bone popped out of his wrist, but he adjusted it back into place and finished the round.[104] Woods then missed the cut at the 2015 U.S. Open and Open Championship, the first time Woods missed the cut at consecutive majors, finishing near the bottom of the leaderboard both times.[105] He finished tied for 18th at the Quicken Loans National on August 2.[106] In late August 2015, Woods played quite well at the Wyndham Championship finishing the tournament at 13-under, only four strokes behind the winner, and tied for 10th place.[107] Woods offered only a brief comment on the speculation that he was still recovering from back surgery, saying it was "just my hip" but offering no specifics.[108]
World Golf Championships-Bridgestone Invitational: Finished T8 at the World Golf Championships-Bridgestone Invitational, which, coupled with his T3 at The Open Championship, gave him back-to-back top-10s in a season for first time since winning the 2009 BMW Championship and finishing runner-up at the TOUR Championship by Coca-Cola. It also snapped a career-long streak of three starts in World Golf Championships events without a top-10. His 11 top-10s at the Bridgestone Invitational, seven of which are wins, is a tournament-high.
World Golf Championships-Dell Technologies Match Play: In his first start at the World Golf Championships-Dell Technologies Match Play since 2013, and first start in the state of Texas since 2005, advanced to the Quarterfinals to finish T5 in the event. Playing at Austin Country Club for the first time in his career, earned two points to advance out of his group after defeating Aaron Wise and Patrick Cantlay. Suffered a 2-and-1 loss to Brandt Snedeker. Went head-to-head with Rory McIlroy for the first time with their match up in the Round of 16. Defeated McIlroy, 2 and 1, before falling to Denmark's Lucas Bjerregaard, 1-up.
Woods had back surgery on September 16, 2015. In late March 2016, he announced that he would miss the Masters while he recovered from the surgery;[109] he had also missed the 2014 Masters due to a back problem.[110] "I'm absolutely making progress, and I'm really happy with how far I've come," he explained in a statement. "But I still have no timetable to return to competitive golf."[111] However, he did attend the Masters Champions Dinner on April 5, 2016.[112] For the first time in his career, he missed all four majors in one year due to problems with his back. In October 2016, he told Charlie Rose on PBS that he still wanted to break Jack Nicklaus's record of 18 major titles.[113] Woods underwent back surgery in December 2016 and spent the next 15 months off the Tour. He made his return to competitive golf in the Hero World Challenge.[114]
A related effect was measured by University of California economist Jennifer Brown, who found that other golfers scored higher when competing against Woods than when he was not in the tournament. The scores of highly skilled golfers are nearly one stroke better when playing against Woods. This effect was larger when he was on winning streaks and disappeared during his well-publicized slump in 2003–04. Brown explains the results by noting that competitors of similar skill can hope to win by increasing their level of effort, but that, when facing a "superstar" competitor, extra exertion does not significantly raise one's level of winning while increasing risk of injury or exhaustion, leading to reduced effort.[163]
Woods was 15 years old and a student at Western High School in Anaheim when he became the youngest U.S. Junior Amateur champion; this was a record that stood until it was broken by Jim Liu in 2010.[40] He was named 1991's Southern California Amateur Player of the Year (for the second consecutive year) and Golf Digest Junior Amateur Player of the Year. In 1992, he defended his title at the U.S. Junior Amateur Championship, becoming the tournament's first two-time winner. He also competed in his first PGA Tour event, the Nissan Los Angeles Open (he missed the 36-hole cut), and was named Golf Digest Amateur Player of the Year, Golf World Player of the Year, and Golfweek National Amateur of the Year.[41][42]
BMW Championship: Captured his sixth title of the season and took the lead in the FedExCup standings with an eight-stroke victory over Jim Furyk and Marc Leishman at the BMW Championship. Shot a third-round, course-record 62 at Cog Hill to take a seven-stroke lead entering the final round and finished at 19-under 265 to win for the fifth time at Cog Hill. It was his 10th career PGA TOUR victory by at least eight shots. It was also his 71st career victory, two short of Jack Nicklaus for second on the PGA TOUR's career list. Also tied Sam Snead with his sixth season of at least six victories.
In 2002, Woods was involved in every aspect of the launch of Buick's Rendezvous SUV. A company spokesman stated that Buick was happy with the value of Woods' endorsement, pointing out that more than 130,000 Rendezvous vehicles were sold in 2002 and 2003. "That exceeded our forecasts," he was quoted as saying, "It has to be in recognition of Tiger." In February 2004, Buick renewed Woods' endorsement contract for another five years, in a deal reportedly worth $40 million.[135]

BMW Championship: Matched the low final round of his career with an 8-under 63 to win the BMW Championship by two strokes for 60th career TOUR victory. Took the lead for good with a 12-foot birdie on the 13th hole and kept his distance from third-round co-leaders Aaron Baddeley and Steve Stricker. Finished at 22-under 262, breaking by five shots the record he set four years prior at Cog Hill.
At age 19, Woods participated in his first PGA Tour major, the 1995 Masters, and tied for 41st as the only amateur to make the cut; two years later, he would win the tournament by 12 strokes. At age 20 in 1996, he became the first golfer to win three consecutive U.S. Amateur titles[54] and won the NCAA individual golf championship.[55] In winning the silver medal as leading amateur at The Open Championship, he tied the record for an amateur aggregate score of 281.[56] He left college after two years in order to turn professional in the golf industry. In 1996, Woods moved out of California, stating in 2013 that it was due to the state's high tax rate.[57]
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]
