American Matt Kuchar won the Players Championship Sunday by two shots to secure the biggest win of his career and a $1.71 million pay check. To the delight of his watching family, Kuchar shot a final round two-under 70 to finish 13-under for the tournament, two clear of Briton Martin Laird (67) and Americans Zach Johnson (68), Rickie Fowler (70) and Ben Curtis (68). Overnight leader Kevin Na had a disappointing finish, making six bogeys in a 76 that saw him slip back into a tie for seventh, a day after being heckled by spectators for his slow play and constant practice shots. Tiger Woods ended well down the field at joint 40th after shooting a 73 to finish one-under. England's Luke Donald finished strongly with a 66 that elevated him to sixth, four strokes behind Kuchar, but not enough for him to regain top place in the world rankings from Northern Irishman Rory McIlroy, who missed the cut. Kuchar, who tied for third at the Masters, consistently avoided trouble on the final day on a course that severely punishes inaccuracy. While his challengers stumbled at various hurdles, the American kept out of water and greenside sand throughout a confident 18 holes. Kuchar wrapped up the tournament when he coolly sunk a 15-foot birdie putt on the 16th to surge three strokes clear. Although bogeying the ‘island green' 17th, the fixed grin never left his face as he went to the final tee with a two-shot cushion. Fowler's second place finish was the fifth of his career and followed his maiden PGA Tour win at Quail Hollow last week. The 23-year-old made a late charge with birdies on the 16th and 17th holes but missed a nine-foot birdie putt on the 18th that would have put more pressure on Kuchar. Kuchar safely parred the last to claim his first PGA title win since the 2010 Barclays at the Ridgewood Country Club in New Jersey. For the third tournament in a row, Woods failed to mount a challenge. He also finished tied for 40th at the Masters before missing the cut at Quail Hollow.
