• American Brian Harman leads by one shot at 12-under after round of 67
• Thomas cards first nine-under-par round in US Open history
It took until this, the 117th staging of the US Open, for a player to post a round of nine under par in this championship. Step forward Justin Thomas, who marched where even the greats of this sport failed by holing out from eight feet on Erin Hills’s 18th green for an eagle. Unprecedented achievement had been sealed courtesy of a Thomas 63. Yet by close of play, he did not even lead the tournament.
Tommy Fleetwood threatened to set a record of his own, until a stumble at the very location where Thomas excelled. Fleetwood could have been only the second Englishman in 47 years to hold at least a share of the 54-hole lead in a US Open but blundered with a chip then putted over the 18th green when it seemed his hard work had been done. A dropped shot means Fleetwood, at 11 under, shares second with Thomas and Brooks Koepka.
