British Open Leaderboard 2013: Latest Day 4 Scores from Muirfield

A star-studded leaderboard at the 2013 British Open provides the backdrop for what should be a classic Sunday finish at Muirfield. 

Through three rounds at the links course in Scotland, we've witnessed surprise contenders like Miguel Angel Jimenez and Jordan Spieth come and go. We've also seen players like Adam Scott, Tiger Woods and Phil Mickelson loom as contenders to make a run on the final day. 

With many of the players already getting their last round started, here's a live look-in at the latest movement on the leaderboard. 

Of course, the serious contenders have yet to tee off. Let's take a look at the contenders to keep an eye on as they put in their final bid for the Claret Jug. 

Lee Westwood

No one will enter Sunday with more pressure than Lee Westwood. 

Not only will he have the pressure of a British crowd hoping to see a Brit win the Open, but he'll be trying to earn his first major after a record seven top-three finishes with no championships, according to Justin Ray of ESPN. 

Westwood has ridden an extremely hot putter to this point. According to TheOpen.com, he leads the field in one-putts with 26, including this amazing eagle putt from Day 3, via CBS Sports. 

The 40-year-old Westwood slept on a two-shot lead after the third day, but that could be gone with just one poor shot. The pressure will be on, and we'll see if he finally has what it takes to break through at a major. 

Hunter Mahan

Lost in the narratives of Westwood and Tiger Woods' struggles to close out majors is the emergence of Hunter Mahan at Muirfield. 

The 31-year-old has yet to win a major in his career, but he has the opportunity of a lifetime to steal one here as the attention primarily focuses on the other contenders.

If he can duplicate the wildly successful round that he had on Day 3, there's no doubt that his chances of winning are strong. He outshot both Woods and Westwood with a 68 that included five birdies. 

It drove his birdie count up to 13, which gave him the 54-hole lead in the category. 

With his ability to get aggressive and make birdies when he has to, Westwood's two-shot lead shouldn't be intimidating. He's a solid pick to hoist the Claret Jug when it's all said and done. 

Ryan Moore

Moore is another contender on Sunday who could benefit from having the bigger names at the top of the leaderboard. 

The 30-year-old has only finished in the top 10 of a major once, but barring a colossal meltdown on the final day, he'll be adding to that count. He ended his third day just four strokes behind Westwood and T-5 on the leaderboard. 

In a tournament that has been characterized by unforgivingly rough and fast fairways, Moore has done an excellent job of making sure he gets on the green in regulation. He's hit 41 greens thus far, which was good enough for second in the field. 

With Moore showing no signs of struggle in getting to the green, it's all going to come down to putting for him. He's averaging 1.65 putts per green through three rounds, which isn't bad, but he'll need to really sink pivotal putts if he wants to be a threat.
