Louis Oosthuizen and Sergio Garcia are among Olympic qualifiers who aren’t going to Tokyo next month. It’s still a big change from 2016 in Rio de Janeiro. Five years ago, the top four players in the world stayed home over concerns of the Zika virus and security. This year’s field features four of the top five in the world and five of the past six major champions. The 60-man field was set Tuesday. Four players from the top 10 aren’t going, but only one by choice. That would be Dustin Johnson. The other three are Americans who didn’t qualify.
