Atwal, the only Indian winner on the PGA Tour, has lost his Tour card and is trying to find that form again to get back into the elite Tour. He had two birdies and four bogeys.
After 12 holes he was even par, but bogeys on 13th and 18th saw him end the day at 72 at the Par-70 TPC Southwind.
Dustin Johnson, the 2012 champ here, was in the group at 66 with Steve Stricker, Jamie Donaldson, Colt Knost, Brian Gay and Miguel Angel Carballo. Retief Goosen, Scott Stallings and Justin Leonard -- all shot 67s. Phil Mickelson matched defending champion Fabian Gomez of Argentina at 70.
