(Reuters) - American Pat Perez, benefiting from a greatly improved mental approach to the game, ended a seven-year title drought on the PGA Tour with a two-shot victory in the OHL Classic at Mayakoba in Mexico on Sunday. In only his third tournament back since being sidelined for eight months by a shoulder injury, the long-haired Perez used a fast start and a clutch finish to seal his second win on the U.S. circuit with a closing four-under-par 67. Fellow American Gary Woodland, the third-round leader, rebounded from a shaky front nine and birdied 17 and 18 for a 70 to finish alone in second with Scotland's Russell Knox (66) a further stroke back at 18-under.
