OAKMONT, Pa. — Rory McIlroy appeared to have found a swing key as he shot 31 on the first nine holes in his delayed second round Saturday morning. He stumbled after that, four-putting the third hole (his 12th).

Despite that, he needed only a par on his final hole to make the cut. But he failed to get out cleanly from a fairway bunker, made double bogey, finished at 8 over, missing the cut by two. He walked quickly from the clubhouse, carrying a long cardboard box and declined to speak with reporters.

Phil Mickelson returned early Saturday for the final two holes of his second round. He made par on both and finished at 7 over, missing the cut by a shot. That left him winless in 26 tries at the U.S. Open, the only major he needs to complete the career Grand Slam.

Mike Miller of Brewster, N.Y., who plays out of Knollwood Country Club in Westchester, followed his solid 2-over-par 72 in the first round with an 81. He missed the cut by seven strokes. “The guy who was marking for us, he works for the USGA. He came up to me and said he expects to see me back, that I’ve got a complete game, and it’s unfortunate the way things panned out. It’s tough to see it right now as an accomplishment. I think I finished 125th,” he said. “In my mind that’s not an accomplishment. A lot of people will never get here, I know that part. But I feel like I can do a lot better.”

Amateur Nick Hardy, a sophomore at the University of Illinois, invited his dad to caddie for him on the final two holes as a Father’s Day gift.

Charley Hoffman “vented” on Instagram Friday, saying, “Can’t play a professional event run by amateurs.” Hoffman, who made the cut on the number, does not have a distinguished history in major championships. He has played in 20, missed the cut 10 times and contended only once, at the 2015 Masters, but then was the only one of the top 16 to shoot over par on Sunday.
