2013 U.S. Open leaderboard: 3rd round underway

It’s moving day at the 2013 U.S. Open and while conditions may be more favorable than they were in the first two rounds, Merion continues to be a challenge.

Nearly half the remaining field has teed off and in the early going, players are still struggling to make pars. Sample sizes are small, but of the eight holes that have been played so far, six are playing over par. The course played at more than five strokes over par in the second round and while it should be lower on Saturday, it won’t be a pushover.

Seven players are currently under par in the third round, including Rickie Fowler, Lee Westwood and Adam Scott. Westwood and Fowler both took advantage of the short Par 3 13th hole, which is playing at just 98 yards. Fowler flirted with an ace as his tee shot spun back toward the hole, leaving a short birdie.

Not everyone is off to a good start, including Sergio Garcia, who is 8-over through five holes on Saturday. Garcia bogeyed two of his first four holes before running into trouble off the tee on No. 15. Garcia hit three straight tee shots out of bounds on the 15th, eventually carding a 10 on the Par 4.

With favorable pins, many are expecting lower scores on Saturday -- Phil Mickelson said a round in the mid-60s could be possible. The conditions could lead to significant movement on the leaderboard as players attempt to make a run into contention.
