The final round of the Open Championship boasts a tight leaderboard with five major champions among the top 10 players and 16 players within 6 shots of the lead, held by Lee Westwood.
The Englishman takes a 2-stroke advantage into the final round at Muirfield. Here is a look at the top contenders, what they did and what is at stake.
Lee Westwood (-3)
On Saturday: Shot 1-under 70, including two clutch putts on the 16th and 17th holes, to take a 2-shot lead over Hunter Mahan and Tiger Woods.
At stake Sunday: An elusive first major championship. Westwood has seven top-3s in majors, the most of any player since the Masters began in 1934 to not win one. At age 40, his opportunities are dwindling.
Hunter Mahan (-1)
On Saturday: Equaled the day's best score, a 3-under-par 68 to forge a final-round pairing with Westwood.
At stake Sunday: For the second straight major, Mahan will be in the final group; he shot a 75 last month at Merion for a fourth-place tie. A winner of five PGA Tour events, Mahan's best finish at the Open is a tie for sixth.
Tiger Woods (-1)
On Saturday: Shot 1-over-par 72, his round marred by a bogey at the par-5 17th hole.
At stake Sunday: Woods hasn't won a major in more than five years but has given himself his best chance through 54 holes in four years. He let a good round get away from him Saturday but has been hitting the ball beautifully.
Adam Scott (Even)
On Saturday: Quietly shot even-par 70 to remain at even for the tournament and just 3 shots back.
At stake Sunday: Scott admitted his mindset is different, not leading and not having the burden of winning a major hanging over his head, after his Masters victory. He's in a great spot, with not much to lose, and is clearly playing steady golf with rounds of 71-72-70.
Angel Cabrera (+1)
On Saturday: Cabrera shot 2-over 73 to drop 4 strokes out of the lead.
At stake Sunday: The two-time major champion is clearly at his best in these situations and can't be counted out. Bogeying two of the final three holes didn't help.
Zach Johnson (+1)
On Saturday: Johnson shot 73 to keep himself in the tournament, but he lost ground to Westwood.
At stake Sunday: The 2007 Masters champion opened the tournament with a 66 but didn't make a single birdie Saturday. That isn't going to cut it if he is to win a second major.
Ryan Moore (+1)
On Saturday: Moore's 72 kept him in the game, and he played the tough back nine in 34 strokes.
At stake Sunday: Moore, a two-time winner on the PGA Tour, is an unlikely challenger. In three previous Opens, he hasn't fared better than a tie for 28th. Perhaps he'll post a number and become a surprise major champion at Muirfield.
Henrik Stenson (+1)
On Saturday: Stenson played in the final twosome but managed just a single birdie, although he made 11 straight pars until a bogey at the 18th.
At stake Sunday: The Swede has two third-place finishes in previous Opens and has won a Players Championship, although he is still emerging from a slump.
Phil Mickelson (+2)
On Saturday: Lefty let a good chance get away Saturday, playing the final six holes in 3 over to drop 5 back.
At stake Sunday: Mickelson has rarely contended at the Open, but he has a chance to shoot a number before the leaders and make them try to match or better his score. To win a fifth major at this point in his career would be epic.
