OWINGS MILLS, Md. — Clutch down the stretch and for six dynamic playoff holes, Patrick Cantlay put a fitting end to an epic battle with Bryson DeChambeau by making an 18-foot birdie putt on the 18th hole to win the BMW Championship on Sunday.

DeChambeau missed a 6-foot putt for 59 on Friday and missed four birdie putts to win in regulation and in the playoff Sunday. And then he missed the most important putt of the week from just inside 10 feet to extend the playoff. It cost him a victory that looked like it was his all along.

“Patty Ice” simply wouldn’t allow it.

He made putts from 8 feet for par, 8 feet for bogey and 20 feet for birdie on the final three holes of regulation for a 6-under 66.
