Tyrrell Hatton is the fourth player to have to withdraw from the Valspar Championship because of a positive test for the coronavirus.
Hatton is the No. 8 player in the world ranking, making him the highest-ranked player to test positive on the PGA Tour since world No. 1 Dustin Johnson in Las Vegas last October.
Sepp Straka, Will Gordon and Brice Garnett also tested positive this week and withdrew. It’s the first time four players have tested positive at a tournament since the PGA Tour returned from the pandemic in June.
