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. 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 wind-blown day that saw just three of the 70 competitors finish with rounds in the 60s.
