Jordan Spieth's little sister was asking more than he could deliver at Erin Hills. The record for a lowest cut was 1-over 145 at Medinah in 1990. He was T-5 or better in all four majors in 2014, but he hasn't had a top-10 since.
A 94-year-old spectator has died at the U.S. Open. No other information was provided.
Fleetwood endured a dip in form past year before reviving his form when he returned to his former coach, Alan Thompson, a move that soon reaped rewards when he won the Abu Dhabi HSBC Championship in January.

"I've never played in [one of the final pairings of] a U.S. Open, so tomorrow will be a very cool experience".
"Yeah, 12 under, I'd have about a 10-shot lead in most Opens", he said. "Hopefully I've got a lot of the bad stuff out of my system yesterday and some parts today". When it was clear he had nothing going in the second round, he was simply trying to stay out of the way.
Brian Harman is the leader at Erin Hills. For all the talk about the 137 brutal bunkers at Erin Hills, this is the only unbunkered hole, and where the driving distance (downwind) has been the longest of any hole on the course: 320.7 yards. This one he'd rather forget.
Then came the par five 14 hole. "So it's just nice to see it come along at the right time". He shot -7 and had a 65 on the day, which was impressive.

And despite carding four birdies in his last six holes for a 71 on Friday, the four-time major victor saw his own pre-event prediction come true, having said on Tuesday that anyone who could not hit the wide fairways "might as well pack your bags and go home".
The Englishman shot a one-under 71 but had to fight back from two bogeys and a triple bogey in his first six holes. But that wasn't the problem. It dropped him two shots off the lead and, to add insult to injury, it will still count as a three-putt.
Just like that, Casey is 4 over for the day and now five shots out of the lead. However, that didn't cut it on a day when McIlroy needed to make birdies galore in order to make his way inside the cut line.
While Erin Hills was still not playing as hard as many past U.S. Open courses, it was beginning to firm up from the early week rain, plus the USGA had a few tricks up its sleeve.

It was the first time since the world ranking began in 1986 that the top three players missed the cut in any major.
