Greenbrier Classic 2012 Leaderboard: Players Outside Top Five Who Are Contenders

Troy Kelly and Webb Simpson have surged to the top of the 2012 Greenbrier Classic leaderboard, but with 18 holes left to play, their lead is far from safe.

The course has been friendly to just about everyone thus far, as multiple players have posted some ridiculous scores. Kelly earned his spot at the top by dropping an eight-under 62 on Saturday, while several other golfers shot six-under on the third day of the tournament.

If the following players can deliver similar performances on Sunday, they will have a great opportunity to walk away with the trophy.

Keegan Bradley (-8)

After a rocky opening day, Bradley has rebounded beautifully. In his last two rounds, he has notched eight birdies and just two bogeys to keep himself in contention.

Bradley already has three top 10 finishes this season, and if he continues to play the way he has the past two days, he will be a serious threat to get his first win of the year on Sunday.

For the tournament, Bradley's is averaging 308.7 yards per drive and hitting 74.1 percent of his greens in regulation. If he can keep those numbers up, he will have a chance to chase down Kelly and Simpson.

Bill Haas (-8)

Haas was fantastic on Saturday, sinking six birdies as he rose up the leaderboard. He also had just one bogey on the day, giving him an impressive five-under 65.

Haas had struggled prior to Greenbrier, missing four of his last six cuts entering the tournament. He's been solid throughout the week, though, reminding everyone that he can often be as dangerous as anybody in the field.

Haas already has one win this season, and with another 65 or 66 on Sunday, he will be in a good position to claim his second.

Steve Wheatcroft (-8)

Wheatcroft caught fire on Saturday, draining six birdies and zero bogeys for a six-under 64. It was a highly unexpected performance, as he struggled throughout the first two rounds, and his recent tournaments hadn't gone too smoothly.

Including Greenbrier, Wheatcroft has played in 14 PGA Tour events this season. Unfortunately, he's missed eight cuts and was forced to withdraw from his last outing at the Travelers Championship.

When you're hot, you're hot, though, and there's no denying that Wheatcroft has as much momentum as anybody in the field. If he continues his strong play on Sunday, he could surprise everyone by winning his first PGA Tour event.
