Ageless Vijay Singh/Halleran/Getty Images The second round of the BMW Championship at Crooked Stick has been completed and amazingly the seemingly ageless Vijay Singh is sitting comfortably at the top of the leaderboard. VJ had a second round score of -6 under par 66, for a tournament total of -13 under par, one shot clear of the chasing pack. Vijay Singh is trying to make the Tour Championship by Coca-Cola for the 17th time. That prowling pack, at -12 under par includes World number one Rory McIlroy, Tiger Woods and Ryan Moore, this is a very closely contested event at the top of the leaderboard. Vijay had 11 one-putt greens on Friday and made 17 of 18 putts inside 10 feet, including four consecutive birdies, which really set him up today; " That kind of got me going. When I did miss the green, I stuck my chip shot very close, so always nice to keep the momentum going." Rory McIlroy said he kind of struggled today, he needed to concentrate on his game; " There was a few struggles going on I think we needed to concentrate a little bit more. Things were sort of coming easy yesterday. We needed to concentrate out there and try and shoot the best score possible, and we obviously both did that. I didn't play as well as I did yesterday but was able to get it around. It seemed like every time I missed the green, I missed it in the wrong spot and left myself difficult chips. But I took advantage of the opportunities that I did give myself, and I just think I’m putting so well recently that any time I do get a look on the green for birdie. I’m sort of making those and that’s making up for some of it." Tiger Woods also admitted that he was not quite right, said he was; " Slapping it everywhere, I didn’t have it with my swing. Just kind of fighting it around here. I was grinding hard, staying as patient as possible. You look up at the scores, the guys are just running off. I just wanted to get to double digits today. I felt like that would have been a good accomplishment the way I was hitting the golf ball." Lee Westwood and Bo Van Pelt are another shot back at -11 under par, just about everybody else is close behind. Those currently not contending too well include, Luke Donald, Sergio Garcia and Brandt Snedeker, all Ryder Cup participants.
