Graeme McDowell defeated fellow U.S. Open champ Webb Simpson in a playoff to win the RBC Heritage on Sunday for his second career victory on the PGA Tour.McDowell was four shots behind when the round started, but rallied with a closing 69 over wind-blown Harbour Town Golf Links in Hilton Head Island, S.C. The 2010 U.S. Open champ had his only bogey of the day on the 72nd hole to force a playoff with Simpson, the reigning U.S. Open titleholder.McDowell struck his approach on the extra hole about 15 feet away and two-putted for par. Simpson could not answer, missing about a 10-footer for par.Luke Donald and Kevin Streelman tied for third.McDowell’s win ended a tough day in which only three players shot in the 60s.Donald shot a 69 while Streelman had a 72. Jerry Kelly rounded out the top five after his even-par 71.Charley Hoffman, the 54-hole leader, ballooned to a 77 and fell into a tie for sixth.Both McDowell and Simpson had the chance to win on the 72nd hole. McDowell missed a 12-foot par putt after his approach went over the green. It was his only bogey on the round.Simpson had a 22-footer for birdie a short time later on the 18th, but sent it 3 feet past to lead to the tournament’s third playoff in four years.McDowell patted Simpson on the back after the playoff miss and smiled widely as the boats in Calibogue Sound tooted their horns and whistles.Neither McDowell nor Simpson made the cut a week ago at the Masters, yet bounced back in a big way at Harbour Town.The course showed its teeth, winds arcing flagsticks and blowing debris on every hole. The National Weather Service issued a wind advisory for the area, warning of winds of 20-to-30 mph and gusts up to 45 mph.“Extremely difficult,” Donald said of conditions. “Strongest wind I’ve played in all year.”Langer winsBernhard Langer added to his impressive Champions Tour season by shooting a 67 to win the inaugural Greater Gwinnett Championship in Duluth, Ga., by three strokes.The 55-year-old Langer, who finished 10 under, took control with a long chip-in for birdie on No. 10.

He also won the Ace Group Classic in Naples, Fla.Tom Lehman, whose 67 included birdies on 17 and 18, tied for second at 7 under with Tom Pernice Jr. Pernice made a move with an eagle on No. 15 and added a birdie on 18 for a 70.Esteban Toledo, the second-round leader, fell out of contention with double bogeys on 11 and 12 on his way to a 75.European TourRaphael Jacquelin of France won a record-tying playoff at the Spanish Open, edging Germany’s Maximilian Kieffer on their ninth try at the 18th hole.
