Ian Poulter ran off four birdies around the turn. Martin Laird was the only player without a bogey on his card. That was enough for them to share the lead Thursday in The Players Championship.
Poulter birdied all of the par 5s on his way to a 7-under 65. Laird played in the afternoon and relied on his putting for some critical par saves to match Poulter.
They were a shot ahead of Blake Adams.
Tiger Woods opened with a 74 and is in danger of missing the cut for the second straight week. Phil Mickelson, inducted into the World Golf Hall of Fame on Monday, had a 71. Rory McIlroy hit in the water on the island-green 17th for double bogey and shot 72.
