Mickelson said after his round that he was returning to his residence "to watch the carnage on TV." He also said he had no chance to make the 36-hole cut.
He was correct and won't be returning to the course today, his 37th birthday. That will break his streak of 13 straight made Open cuts.
Mickelson hurt his wrist here practicing shots out of deep rough, which he said was twice as long as it is now. He said the wrist was fine yesterday except for being sore.
"It's disappointing to dream as a kid about winning the U.S. Open and spend all this time getting ready for it" and then suffer an injury, he said. "You're trying to win and hit great shots but you're also trying to not end your career on one shot, or at least suspend it for a while. That's a little disappointing."
Mickelson made his first birdies of the U.S. Open on the fourth and six holes but was done in on the seventh through the 10th, where he carded a pair of bogeys and two double bogeys, including a four-putt at the 10th.
Angel Cabrera was asked if he should say anything to Mickelson the next time he saw him because of the shot that knocked Mickelson out of the Open.
"I did not knock out Mickelson," he replied. "Mickelson knocked out himself, so I don't think I have to say anything. He shot 11 over par."
Big names fall
The Open was cruel to some of the world's greatest players.
Of the top 10 players in this week's World Golf Rankings, Mickelson (No. 2), Adam Scott (No. 4), Henrik Stenson (No. 6), Luke Donald (No. 9) and Retief Goosen (No. 10), a two-time U.S. Open champion, missed the 36-hole cut.
Of the five top-10 players to stay around, only Tiger Woods, at 145, was within 5 strokes of Cabrera.
"I feel like today's round could have gotten away a little bit," Woods said after his 74. "I didn't make any doubles and I had a three-putt on 15, but other than that, I felt like I hung in there really well."
In addition to West Chester's Sean O'Hair, who shot an 80 for a total of 153, two other players with Philadelphia connections - Plymouth Whitemarsh High School graduate Joe Daley and former Temple star Geoffrey Sisk - missed the cut.
Daley had a 76 and a total of 153, and Sisk a 79 and 156.
Amateur Richard Lee
, at 15 the second-youngest contestant ever to compete in a U.S. Open, withdrew after 13 holes because of what was apparently a sprained right wrist.
Lee, of Canada, said he hurt the wrist at the 11th hole while trying to hit a wedge out of deep rough beside the green. Lee continued on to the 12th and 13th holes before walking in.
"It hurt a lot," he said. "I was trying to concentrate but I couldn't. There was a lot of pain to my wrist."
