Rickie Fowler fired 10 birdies in a US Open record-low round of 62 on Thursday and Xander Schauffele matched it minutes later to share the first-round lead at Los Angeles Country Club.

Fowler, fighting out of a slump that saw him miss the past two US Opens, overcame two bogeys in his eight-under-par effort and surpassed the previous tournament record low round of 63, first set by Johnny Miller at Oakmont in 1973.
