Just four of the top-10 golfers have teed off on Friday at The Barclays, but one of them has already made a push to the top. Vijay Singh finished his round at 4-under and is tied with Padraig Harrington atop the leaderboard at 7-under.

Singh had four birdies and no bogeys in his second round of play.

Several of the notable names near the top of the leaderboard have yet to begin play. These include:

• Harrington (7-under): 12:22 p.m. tee time
• Sergio Garcia (5-under): 12:44 p.m. tee time
• Phil Mickelson (3-under): 12:44 p.m. tee time
• Tiger Woods (3-under): 1:06 p.m. tee time

The projected cut is at even par, which poses a struggle for Richmond native John Rollins. He is at 1-over and is set to tee off at 12:33 p.m.
