Kim started the final round tied for the lead
American Anthony Kim needed a play-off before clinching his third PGA tour title at the Houston Open.
The 25-year-old overnight leader had to withstand a strong final-round surge from compatriot Vaughn Taylor.
Taylor holed a superb 15-foot putt to level the match at 12 under before Kim missed a six-footer on the 18th.
Kim then held his nerve to par the first extra hole and clinch the victory with Charl Schwartzel and Graham Delaet a further shot back in joint third.
It was the second year in a row that the event, which is the last before the Masters at Augusta, went to a play-off.
Twelve months ago Briton Paul Casey beat J.B. Holmes with a bogey on the first extra hole after the American drove into the water.
