The second round of the BMW Championship is in the books, and Vijay Singh's score of 66 on Friday has vaulted him into sole possession of the lead at 13-under par.

Low numbers were being fired all day long at Crooked Stick Golf Club in Carmel, Ind. Sitting at 12-under and a shot behind are Tiger Woods, Rory Mcilroy and Ryan Moore, while Lee Westwood and Bo Van Pelt are only two back from the lead at 11-under in what should be an exciting weekend in the third leg of the FedEx Cup playoffs.

University of Illinois alums Steve Stricker (3-under, 1-over for the round) and D.A. Points (1-over overall, 1-under for the day) are a few shots off the lead, while Northwestern University alum Luke Donald shot an even par round and remains at 6-under par. Illinois resident Mark Wilson finished the day at 4-over par.
