Phil Mickelson's final round in this year's major championships nearly came two days earlier than he really wanted.

World number two Mickelson squeaked inside the cut on the number Friday in the 91st PGA Championship, firing a two-over par 74 for the second day in a row to finish on four-over 148 and stand among 80 who reached the weekend.

Mickelson has struggled with the putter, having made 77 putts over 36 holes.

"I'm not going to beat many people putting the way I am," Mickelson said. "I've got to get this thing turned around."

Mickelson spent a rare post-round practice putting session Thursday but solved none of his headaches, even though he clawed back from a double bogey at the fifth with an eagle on the par-5 seventh.

"I think the struggling on the greens is carrying over a little bit into maybe my focus on some other shots," Mickelson said. "I don't feel I'm hitting it bad, but I'm hitting some bad shots.

"I don't feel like I'm striking it horrendously. It's just I'm having trouble scoring right now."

Mickelson, a two-time Masters champion who also won the 2005 PGA Championship, has not missed a cut in a major since the 2007 British Open and has not missed a cut in a PGA Championship since 1995.

The 39-year-old American left-hander skipped the British Open last month while on a break to be with his wife and mother as they began treatment for breast cancer.

Mickelson settled for his record fifth runner-up finish at the US Open in June and did not play a tour event again until last week's World Golf Championships Bridgestone Invitational, where he shared 58th place.

"I think he's fine emotionally and he probably has not been able to put in the time with his golf game that he wants," playing partner David Toms said of Mickelson.

"He's grinding pretty hard. He hit some wayward shots and that cost him a lot of strokes but as far as competitive spirit he seems like he's into it."

Mickelson will play in two weeks at the Barclays in the first tournament of the US PGA Tour's season-ending playoffs but with his family scheduling medical treatments, committing to anything else is too much to ask right now.

"I don't want to look too far down the road for at least another year, because we're day to day with everything," Mickelson said. "Right now things are OK, I'm planning on playing Barclays and we'll see where I go from there."
