It didn’t take long for Arjun Atwal to break from the pack of players at 4 under. Atwal, who began his second round on the back nine, birdied No. 10, rolling in a putt from just over 20 feet. That gets him to 5 under for the week and gives him eight birdies over his first 21 holes here at Aronimink.

Atwal is only in the field because of a sponsor’s exemption – being a practice partner of Tiger Woods certainly helps – and is playing this season on a Major Medical Extension because of a shoulder injury that cost him four months last year.

Though Atwal has never won on the PGA TOUR -- his best finish is a tie for second at the 2005 BellSouth Classic -- he has won elsewhere, including on the Nationwide Tour, where he beat Webb Simpson in a playoff at the 2008 Chattanooga Classic. He’s also won three times in Europe and in 2005 led the TOUR in putting average.

With a little more than $300,000 earned so far this year, Atwal needs just over $280,000 between this event and his next to gain status for the rest of the season. -- Brian Wacker
