Chicago: Justin Thomas faltered in the final round at the BMW Championship on Sunday but held on for an ultimately comfortable three-stroke victory at Medinah in suburban Chicago.
He carded a closing four-under 68 to finish on a 25-under-par total of 263, while fellow American Patrick Cantlay shot a 65 for second place on 22-under.
Thomas started the day with a six-shot advantage but when he bogeyed the 10th hole, after almost hitting his second out of bounds, the lead over Cantlay was down to two.
But Thomas steadied with clutch play over the next three holes, twice holing putts of around 12 feet to re-establish his authority.
“Patrick made that very interesting,” a relieved Thomas said. “I hit the ball so bad to start the day. But I stayed patient and that birdie on 11 was huge.”
