There are some surprising names at the top of the Masters leaderboard. After two rounds, the likes of Jason Dufner are ahead of tough competitors like Tigers Woods and Phil Mickelson.
However, expect Dufner and others to struggle when Day 3 rolls around.
Watson (tied for third at 4-under par) is a lefty who hasn't had much success on the PGA Tour.
A tremendous driver, the 33-year-old Watson has five professional wins with three coming from the PGA.
Watson did place second in the 2010 PGA Championship to Martin Kaymer in a one-stroke playoff loss. Watson had an advantage after the first hole, but his second shot landed in the water hazard in the last hole.
The Masters hasn't been kind to Watson, who never finished above 20th place.
Miguel Ángel Jiménez
Jiménez (tied for third at 4-under par) has done well on the European Tour, but he's failed to translate that success to the PGA.
The 48-year-old Jiménez won 21 times in his professional career, though 18 of those were on the European Tour.
As majors go, the Spanish Jiménez finished second in the U.S. Open (2000), third in the British Open (2001), eighth in the Masters (2008) and 10th in the PGA Championship (1999).
Jiménez was cut three times from the Masters and finished 27th or lower four times.
Couples won the Masters once. But that was in 1992.
Now 52, Couples has placed 15th or lower in nine Masters since. He was cut from the field twice (2008, 2009).
In other majors, Couples had placed second in the 1998 Masters, second in the PGA Championship (1990), and tied for third in the U.S. Open (1991) and British Open (1991, 2005).
Couples finished his second day tied for first at 5-under par. Couples does have 54 career wins and 15 on the PGA Tour, but his best golfing days are behind him.
Dufner has been very impressive his first two rounds of the Masters. However, his hot swing won't last.
The 35-year-old American golfer leads the field with Couples with a 5-under par mark. Dufner doesn't have much majors experience as he was cut five times in 11 tries.
He was 30th at last year's Masters, never finished higher than 40th in the U.S. Open but did fairly well in the 2010 and 2011 PGA Championship (tied-fifth and second).
This is only Dufner's second time on Augusta's course, so expect him to drop off Saturday.
