The best round of the day so far belongs to John Merrick, who just shot a 4-under 66 after closing with four birdies over his last five holes to move 34 spots up the leaderboard. Only one of those closing birdies came from inside 10 feet for Merrick, who had a 31 on the back nine here at Aronimink.
Vijay Singh, meanwhile, is still out on the course and is 4 under through his first 11 holes with birdies on four of his last six holes. That has Singh at 3 under for the week and up 32 spots on the leaderboard in a tie for sixth at the moment. -- Brian Wacker
