Rory McIlroy rallied from six shots behind Monday and closed with a 6-under 65 to win the Deutsche Bank Championship for his first PGA Tour victory of the year.

One week after working with a new putting coach and changing putters, results came quickly for McIlroy. He closed out the front nine with three straight birdies to take the lead and got up-and-down from a bunker for birdie on the final hole as a finishing touch.

Paul Casey, who started the final round at TPC Boston with a three-shot lead, needed to hole a 60-foot eagle putt on the 18th hole to force a playoff. Casey was trying to win on the PGA Tour for the first time since 2009.

McIlroy won for the 20th time in his career worldwide.
