"Our purse is $21.5 million. Winner's check is $4.3 million. We didn't raise our purse this year," USGA CEO Mike Whan said. "When I started at the USGA just four years ago, our purse was $12.5 million, so I feel comfortable that we've been a leader in moving fast and bigger. [...] We want the money to be commensurate with the achievement."
