The foundation benefits from the annual Chevron World Challenge and AT&T National golf tournaments hosted by Woods. In October 2011, the foundation hosted the first Tiger Woods Invitational at Pebble Beach. Other annual fundraisers have included the concert events Block Party, last held in 2009 in Anaheim, and Tiger Jam, last held in 2011 in Las Vegas after a one-year hiatus.
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.
Woods overcame difficulties with stuttering as a boy. This was not known until he wrote a letter to a boy who contemplated suicide. Woods wrote, "I know what it's like to be different and to sometimes not fit in. I also stuttered as a child and I would talk to my dog and he would sit there and listen until he fell asleep. I also took a class for two years to help me, and I finally learned to stop."
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.
