At-a-glance: Day 2 at the Masters

Hunter Mahan had finished in the top 12 at Augusta three of the past four years, but he won't be around on the weekend.

He followed his first-round 76 by shooting a 10-over-par 82 Friday that included four double bogeys.

Angel Cabrera has done little of note since winning his second major championship in the 2009 Masters, but the 43-year-old Argentine was the star of a group that included Sergio Garcia and Adam Scott.

Cabrera closed with birdies in five of the final six holes, a run that moved him from 1 over to 4 under and tied for fourth going into the third round.

"I was hitting very well off the tee, leaving my second shots close, and I was able to make some birdies," Cabrera said.

Dustin Johnson was steamrolling through Friday's round, leading the tournament at 7 under, but a dismal finish ruined his day.

He laid up at the par-5 15th hole, then dunked his third shot in the water, leading to a double bogey. He bogeyed the 17th and took another double bogey at the final hole to finish with 76.

Phil Mickelson came into Friday thinking the conditions would be right for players to separate themselves. For eight holes, he appeared to be among that select group.

Then his approach at No. 9 dealt him a harsh blow, knocking a wedge into the bunker.

"And I hit just an awful shot in the bunker," Mickelson said. "And then I had a pretty easy bunker shot. It was on an upslope, a good lie, and I caught it half-spin, 15-, 18-feet long."

Smarting over the resulting bogey, Mickelson bogeyed No. 10 and double bogeyed No. 12. He finished with a 76 for a two-day total of 3-over 147.

Bill Haas rolled in an eagle, a short iron that bounced twice and rolled straight into the cup at the 460-yard, par-4 ninth. It was one of 11 eagles Friday, and one of three to come from the fairway.

Dufner's approach landed just inches left of the hole, and as the gallery around the green roared, it rolled out to four feet. As consolation, though, Dufner, made the birdie putt.

"You asked me that last year and I said, yeah, I would quit. I'm going to quit when I win this thing, I swear to God. I'm going to retire. It's probably not ever going to happen, but I'm going to retire." — Fred Couples, at 53 in the hunt for a second green jacket to add to the one he won 21 years ago.

Rory McIlroy and Charl Schwartzel will tee off at 12:25 p.m.; Tiger Woods and Gonzalo Fernandez-Castano go 20 minutes later; and the final pair of Jason Day and Couples go at 1:45 p.m.
