World number two Phil Mickelson crashed out of the Crowne Plaza Invitational in Fort Worth, Texas after a three-over-par second round 73.
The American was off colour yesterday as he fired a one-over 71 but things got worse today, with a run of bogeys on the third, fourth and fifth holes and others on the 11th and 12th.
Bryce Molder leads by one stroke at 13-under after an eight-under 62, while Englishman Brian Davis sits in a two-way tie for third on 11-under.
Mickelson was quick to hold his hands up after missing the cut.
“I played terribly,” he told pgatour.com. “I don’t know what to say. I haven’t played the course since the changes. The changes are fabulous. The course is in great shape.
“There was no wind and there were a lot of birdies out there. And I just played terribly. But I will take the weekend. It’s a good barometer for me to know that starting my US Open run, which is here, I’ve got a lot of work to do.”
Davis’ five-under 65 today came despite having overnight hospital treatment to remove a mouth abscess.
“It’s just one of those things, I went last night and had it taken care of,” said Davis.
“Obviously I’ve got a lots of swelling still so it will take a few days to go down, but I’ll be fine.”
Leader Molder said after his round: “It’s a good position, one of the last groups on Saturday, and I can have some fun.
“It’s been a strange two days with no breeze, really warm, but really good scoring conditions and fortunately I was just able to capitalise.”
Jason Bohn remains well in contention in second, a shot off Molder, having recorded a 65 after yesterday’s 63.
England’s Paul Casey and Scot Martin Laird were both four-under, in a tie for 36, nine shots off the lead.
