PONTE VEDRA BEACH, Fla. — At 21, Si Woo Kim is the same age as the No. 1-ranked men’s amateur, Maverick McNealy. But while McNealy was preparing to lead Stanford in an N.C.A.A. regional tournament that starts Monday, Kim turned back the deepest field in professional golf to win the Players Championship.
With a closing three-under-par 69 at T.P.C. Sawgrass on Sunday, Kim became the youngest winner of the tournament, which featured 48 of the world’s top 50 players. His score of 10-under 278 was three strokes better than Ian Poulter of England (71) and Louis Oosthuizen of South Africa (73).
