Not surprisingly, Tiger's built a nice career of wins, money and corresponding exemptions to play everywhere he wants but the World Golf Championship events.
Bob Harig has put together an interesting ESPN.com look at Tiger's status on the PGA Tour and in majors, including what happens in the U.S. Open after his 2018 exemption. His PGA Tour status is also of note:
Although Woods has not finished among the top 125 in the FedEx Cup standings or money earnings since 2013 -- the basic barometer for exempt status -- he should have few worries about playing a full schedule, if he chooses.
For 2018, Woods is exempt based on his 2013 Players Championship victory, which comes with a five-year exemption. Once that expires, his Lifetime Member exemption would kick in, which gives exempt status to a player who has at least 20 PGA Tour victories. Davis Love III and Vijay Singh are using that exemption in 2018
