NORTON, Mass. — Chris Kirk made three big putts and captured the biggest win of his career Monday in the Deutsche Bank Championship. Whether that was enough for U.S. captain Tom Watson to add him to the Ryder Cup team was the least of his concerns.

Kirk won for the second time this season. He went the last 37 holes at the TPC Boston without a bogey. He played the final two rounds with Rory McIlroy and outplayed the No. 1 player in the world. And he closed with a 5-under 66 for a two-shot victory.

Billy Horschel had a chance to at least force a playoff — and possibly win — when he stood in the fairway on the par-5 18th hole with a 6-iron in his hand. Horschel chunked the shot badly.
