(CNN) -- Tournament star attraction Phil Mickelson endured another miserable day at the FBR Open in Arizona to comfortably miss the halfway cut after a second round 73.
Mickielson was well below his best as he missed the cut at the FBR Open.
Combined with his sorry five-over opener for a 76, it left the American left-hander well off the projected cut of even par.
With the final group still to complete their round, Nick Watney leads after a magnificent eight-under 63 to go into the clubhouse on 133 - nine-under.
Mickelson never got to grips with the TPC of Scottsdale although marginally improving on his "disgusting" first round effort.
The two-time tournament winner was missing the cut at his opening event of a PGA Tour season for the first time and clearly unhappy.
" It just didn't come together. I didn't play well," Mickelson told Press Association.
"The course is beautiful. It's in great shape, and it's an exciting time here with the Cardinals being in the Super Bowl. But I didn't get that momentum and play well."
Mickelson, a local favorite who played his college golf at Arizona State University, is determined to perform better next week in San Diego.
"I didn't feel as far off as the score indicated obviously, but I'll get some good work done this weekend and hopefully come out sharp and ready to play next Thursday in San Diego," he added.
Watney,.chasing his second career title, is one-stroke clear of Charley Hoffman, Matt Kuchar and Australian James Nitties.
"I was hitting the ball close, and I kept telling my caddie just to get me on the green anyway and I felt like I could hole it," Watney said.
Ryder Cup hero Kenny Perry fired a 63 with seven birdies and eagle and one bogey to pull within two shots of the lead at seven-under while Cameron Beckman carded a 67 to join Perry in a tie for fifth.
