Collin Morikawa may have one of the grossest habits on the PGA Tour. But he also has an uncanny ability to win golf tournaments.

Morikawa has won three majors in his young career, including the 2020 U.S. Open and 2021 Open Championship. He’s also won four other PGA Tour events, including the 2021 DP World Tour Championship.

Despite his success, Morikawa has become known for a peculiar habit: spitting into the hole after he putts.

Morikawa said he started spitting into the hole when he was a junior golfer. He said he was trying to clear his throat of saliva before he putted, and the habit just stuck.

“It’s not something I do on purpose,” Morikawa said. “It’s just something that happens.”

Morikawa’s habit has drawn some criticism from fans and fellow golfers. But he doesn’t seem to mind the negative attention.

“I’m not going to change who I am because of what other people think,” Morikawa said. “I’m comfortable with who I am and how I play the game.”
