“Well, it’s generally optimal to not lose $360,000.”

The Peabody brothers had taken a $360,000 position on Bryson DeChambeau not to win the U.S. Open at -2400 odds and that sarcastic text reflected their current dilemma. If DeChambeau did not win the tournament, the Peabody’s would win $15,000. But when the text from Tom arrived ahead of the final round, DeChambeau was leading by three shots.

Entering the tournament, Rufus thought the odds of DeChambeau not winning were closer to -3200, so he believed having to pay only -2400 was a bargain.
