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 in a FedEx Cup playoff event.

Was it enough to convince Watson that he was worthy of a captain’s pick?

Then he looked at the blue trophy next to him and considered what he had just achieved.

“Winning the Deutsche Bank and going to No. 1 in the FedEx Cup, and $1.4 million, that’s plenty for me for one day,” he said with a smile.

Watson announces his selections tonight in New York.

Ten shots behind after the opening round, Kirk was so disgusted that he skipped his usual practice session. He was flawless the rest of the week, particularly on Monday in another wild Labor Day finish at the TPC Boston.

Kirk made three big putts on the back nine — two of them for birdie — but what pleased him the most was his 15-foot putt for par on the 15th hole that kept him in the lead.

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 so badly that it barely reached the hazard, and he made bogey for a 69.

Horschel tied for second with 54-hole leader Russell Henley (70) and Geoff Ogilvy, who extended his unlikely run through these FedEx Cup playoffs. Ogilvy was the last of the 100 qualifiers for the Deutsche Bank Championship. He went 65-65 on the weekend without a bogey.yer in four years to go from No. 100 to the third playoff event.
