BROOKLINE, Mass. – Canada’s Adam Hadwin rode a hot start in the more difficult afternoon conditions to surge past the clubhouse leaders and set himself one shot clear of the crowd after one round of the U.S. Open at The Country Club.

Hadwin overcame an early bogey on the third hole to finish with a torrid run of five birdies in the last six holes of the front nine to take the outright lead at 4-under. He bounced back from a bogey on 12 with a birdie on 13 to re-stake his claim to the top and glided home to set the first-round mark at 66.
