FARMINGDALE N.Y. --  Vijay Singh, who won the FedExCup in 2008, has made a big move up the leaderboard.

The ageless 49-year-old is currently 6 under and one shot off Padraig Harrington's overnight lead after making three birdies over his first 12 holes. Harrington doesn't tee off until 12:22 p.m. ET.

Also gaining ground is Bob Estes, who started on the back nine and had three birdies in his first five holes. He's joined the group at 5 under.

Martin Laird has just made the turn in 34 and is among a big group at 3 under along with PGA TOUR rookie John Huh, who has made two birdies in his first seven holes, and Tom Gillis who just made consecutive birdies at Nos. 6 and 7.

Jimmy Walker and Rickie Fowler are also at 3 under but headed in the wrong direction. Walker bogeyed his first two holes and has reeled off nine pars since while Fowler, who is playing in the group behind, is 1 over for the day.

Ian Poulter, who is hoping to be one of Jose Maria Olazabal's two Ryder Cup picks on Monday morning, had moved to 4 under early in his round. But back-to-back bogeys at Nos. 2 and 3, which were his 11th and 12th of the round, have dropped him back to 2 under.

Granted, it’s early. But right now it’s looking like you’ll need to finish two rounds at even par or better to play the weekend.
