The Barclays at Bethpage Black took revenge on Padraig Harrington in the second round, he shot a +4 over par round of 75, which left him with a tournament total of -3 under par. He is not yet out of it, but the course humbled him today. The leaders after the second round are sitting at the top of the scoreboard with a tournament total of -8 under par. Last weeks winner, Sergio Garcia is one of them with his 66, 68, start. He is joined by American Nick Watney who had a good 2nd round of 69, to go with his opening effort of 65. Sergio Garcia & Nick Watney/Getty Images Just one shot back are the big Fijian Vijay Singh, who has won The Barclays four times, although not at this venue, he shares second place with Bob Estes. Both of these players shot lower rounds today than their opening efforts, Vijay with 68, 67, and Bob with 69 and 66. Best round of the day went to Henrik Stenson who sailed round in 65, a -6 under par score to go with his opening round of +2 over par 73, and tournament total of -4 under par, tied for eleventh spot. Tiger Woods tweaked his back when he slept awkwardly,on a soft bed at his hotel Thursday night, he said of the injury; "As I warmed up, it got progressively worse, and then you saw what happened on the golf course. It didn’t feel very good, but I got it around, and just because the swing didn’t feel very good doesn’t mean I can’t make every putt. I went out there with that kind of mindset and just buried a bunch of putts. It was like a section of movement, so it didn’t hurt standing up, it didn’t hurt at the bottom of a squat, but it was the somewhere in-between there it was going to catch. It would grab just before impact, so you’d kind of expect it, so I could get through that. So I’m right there, this is a very bunched leaderboard. There are so many guys there. I think, what, 70-plus guys within nine shots as of right now." Tiger intends to sleep on the floor tonight, he managed a smile as he said; "I’m probably going to sleep on the floor, I do that in Europe all the time, so this is nothing new. I’ve been through that kind of stuff before, so I know what it feels like." Tiger Woods, bending gingerly on the green/Cox/Getty Images At -5 under par Tiger is definitely in the chase for the title. Rory McIlroy on the other hand has slipped back to even par for the tournament with today's round of +2 over par, and unless he produces something very special tomorrow he looks out of contention. There is a slight possibility that rain will affect Saturday’s third round, according to the forecast for The Barclays, and also the winds will pick up over the weekend to 15 mph.
