“Lefty” shot a second-round 73 and won’t be playing through the weekend.
The U.S. Open is the only major Mickelson hasn’t won.
Mickelson’s fellow LIV Golf competitors Sergio Garcia and Louis Oosthuizen also missed the cut.
The projected cut line was set at 2-over-140 to make the weekend. Mickelson was at the bottom of the leaderboard, shooting a 151 over the first two rounds.
On Thursday, Mickelson finished with a 78. He had five bogeys, two double bogeys and one birdie in the fist round. On Friday, he shot a 73, but it wasn’t good enough to push him past the cut line. He finished with two birdies and five bogeys.
Mickelson had increased attention during the tournament after playing in LIV Golf’s first tournament in London last week and finishing 11-over par in the three rounds he played. The Saudi-funded golf league has no cut line.
It was his first tournament against other PGA Tour pros since February. He received heavy backlash for seemingly brushing off Saudi Arabia’s involvement in the murder of Washington Post columnist Jamal Khashoggi.
He later apologized for the remarks but said him joining the rival league was the right thing for him to do.
He reportedly received a $ 200 million deal to participate.
