Watch: Bryson DeChambeau hits 427-yard drive in Round 1 of U.S. Open

Playing downwind and downhill helped. A bounce off asphalt played a large part. But a 427-yard drive is a 427-yard drive.

Bryson DeChambeau launched his tee shot on the 472-yard, par-4 12th — his third hole — in Round 1 of the U.S. Open at Shinnecock Hills. The ball caught the air stream, hit hard on the fairway, bounced off Tuckahoe Road, and settled 45 yards from the hole.

DeChambeau made birdie and followed it up with another on the par-4 13th to reach 2 under par early in his opening round. Sam Stevens shot 2-under 69 to hold the clubhouse lead.
