(Reuters) - Rookie Austin Cook sank a 14-foot birdie putt on the final hole to seal a four-stroke victory at the RSM Classic on Sunday and claim his first PGA Tour title.


The 26-year-old shot a final-round three-under par 67 in windy conditions to finish on 21-under 261 at Sea Island, Georgia. J.J. Spaun shot a 66 to seal the runner-up spot at 17-under 265 with Brian Gay (68) another stroke back.


Cook, who took a three-stroke lead in the final round, dropped a stroke at the second hole but did not let the pressure get to him and remained sold for the rest of the round, picking up shots at seven and 15 before a pleasing birdie-birdie finish.
