Justin Thomas held his nerve in glorious style to win a fraught play-off against Will Zalatoris in claiming a second US PGA title in five years at Southern Hills. The 2017 champion began the day seven strokes behind overnight leader Mito Pereira on minus two, but a 67 saw him reach five under as the unheralded Chilean collapsed on the final hole to card a 75 and agonisingly miss the play-off by a stroke. Ad/> Pereira, 27, held a one-shot lead on the 72nd hole, but emptied his drive into the water in the creek before running up a closing double-bogey six with Thomas and fellow American Zalatoris safely in the clubhouse.
