Surgery: Pulled out of next two PGA TOUR starts, the Genesis Open and The Honda Classic. Released statement: "My doctors have advised me not to play the next two weeks, to continue my treatment and to let my back calm down. This is not what I was hoping for or expecting. I am extremely disappointed to miss the Genesis Open, a tournament that benefits my foundation, and The Honda Classic, my hometown event. I would like to thank Genesis for their support, and I know we will have an outstanding week." In April, announced on his website he had undergone further back surgery. The operation was performed by Dr. Richard Guyer of the Center for Disc Replacement at the Texas Back Institute.
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.
Chevron World Challenge: Lost in a playoff to Graeme McDowell at the Chevron World Challenge. It was the first time as a professional that he lost after holding a three-shot-or-more lead entering the final round. McDowell drained a 20 foot putt on the 72nd hole to force a playoff and then made a 25 foot putt on the first playoff hole (No. 18) to capture the win. The world's No. 2-ranked player missed a 14-foot putt that would have extended the playoff. He has finished in the top two at this event in eight of his 10 starts.
World Golf Championships-Bridgestone Invitational: Collected his sixth title at the World Golf Championships-Bridgestone Invitational in Akron. Won by eight strokes after a closing 5-under 65 at Firestone CC. Joined Jack Nicklaus (Masters/Augusta National), Sam Snead (Miami Open/Miami Springs G&CC) and Alex Ross (North & South Open/Pinehurst No. 2) as the only players to win six TOUR events on the same course.
Earned his 80th PGA TOUR victory and first since 2013, winning the TOUR Championship for the third time in his career to move within two of Sam Snead's TOUR-best 82 victories. Finished the season No. 2 in the FedExCup, with runner-up finishes at the Valspar Championship and PGA Championship among his seven top-10s. Led the TOUR in Strokes Gained: Approach the Green (0.938) for the sixth consecutive season in which he played the minimum number of rounds. After originally being selected as a Captain's Assistant for the United States Ryder Cup team, was later selected as a captain's pick and played in the event for the eighth time.
Woods played in his first 2020 PGA Tour event at the Zozo Championship in October 2019, which was the first-ever PGA Tour event played in Japan. Woods, who played a highly publicized skins game earlier in the week at the same course as the Championship, held at least a share of the lead after every round of the rain-delayed tournament, giving him a three stroke victory over Hideki Matsuyama. The win was Woods's 82nd on Tour, tying him with Sam Snead for the most victories all time on the PGA Tour.
