Vijay Singh leads the 2012 BMW Championship after a second-round 66 brought him to 13-under for the weekend. Singh is one shot ahead of the second-place trio of Ryan Moore, Tiger Woods, and Rory McIlroy.
Moore matched Singh's 66 to stay within a stroke of the leader on Friday. Moore needs a strong tournament to move into the top 30 of the FedEx Cup standings and assure himself a spot in the Tour Championship. He came into the BMW Championship in 35th, but would be projected to move into 11th with a second-place finish.
Woods and McIlroy are tied with Moore at 12-under. Woods played a clean Friday round, shooting five birdies and no bogeys, while McIlroy was all over the place. McIlroy shot six birdies, an eagle, and four bogeys to finish at 4-under for the round.
John Huh, who was born in New York City, made a big move up the leaderboard with a second-round 66. Huh now finds himself in 13th place, five shots back of the leader. If he is still there at the end of the weekend, it is projected that he would squeeze into the top 30 of the FedEx Cup standings at 29th.
Keegan Bradley, who attended school at St. John's, doesn't need quite as high a finish to get into the Tour Championship, as he entered the weekend 12th in the standings. Bradley shot a 2-under 70 on Friday and currently sits in 46th for the weekend.
