Arnold Palmer Invitational presented by MasterCard: Carded a final-round, 2-under 70 on a Monday finish to defeat Justin Rose by two strokes at the Arnold Palmer Invitational, winning the event for a PGA TOUR record-tying eighth time (Sam Snead at the Greater Greensboro Open). His 77th career PGA TOUR win moved him within five wins of all-time leader Snead's 82 victories. With wins at the Cadillac Championship and Arnold Palmer Invitational, he won in back-to-back starts for the first time since the 2009 Buick Open and World Golf Championships-Bridgestone Invitational. Supplanted Rory McIlroy for the No. 1 position in the Official World Golf Ranking. The last time he held the top spot was on October 30, 2010. Surpassed Ernie Els for most weeks in the top 10 of the Official World Golf Ranking, at 789. Had a record run of 736 consecutive weeks in the top 10 from April 13, 1997, to May 15, 2011. Returned to the top 10 on March 25, 2012, where he has since remained. Of his eight Arnold Palmer Invitational wins, has entered the final round with at least a share of the 54-hole lead seven times. Made his 17th start at the Arnold Palmer Invitational, with his lone missed cut coming as an amateur in his first start, in 1994. He has played in every event at Bay Hill since, with the exception of 2010.
PGA Championship: Despite not hitting a fairway until the 10th hole Sunday, made eight birdies and two bogeys to post a 6-under 64, tying the day's low round. Finished solo-second at 14-under 266, two strokes behind Brooks Koepka. The runner-up finished marked his 31st on the PGA TOUR and first time taking solo-second since the 2009 TOUR Championship. Was looking to tie Jack Nicklaus and Walter Hagen for most PGA Championship victories. A win would have marked his first major championship title since the 2008 U.S. Open, a span of 3,709 days.
Buick Invitational: In first start of PGA TOUR season at the Buick Invitational, came from two strokes back in the final round to post seventh consecutive TOUR victory, dating back to the 2006 Open Championship. Victory was fifth career Buick Invitational triumph, his third event with five-plus victories (CA Championship and Bridgestone Invitational, both six times), and the 55th of his PGA TOUR career.
Early in Woods' career, a small number of golf industry analysts expressed concern about his impact on the competitiveness of the game and the public appeal of professional golf. Sportswriter Bill Lyon of Knight Ridder asked in a column, "Isn't Tiger Woods actually bad for golf?" (though Lyon ultimately concluded that he was not). At first, some pundits feared that Woods would drive the spirit of competition out of the game of golf by making existing courses obsolete and relegating opponents to simply competing for second place each week.
