After a second consecutive loss, Coach Adam Oates tinkered with his forward line combinations for Friday’s practice. Wojtek Wolski, who is pointless in the past seven games, is skating on the third line with Mathieu Perreault and Joel Ward after spending the bulk of the season playing left wing on a line with Nicklas Backstrom and Troy Brouwer. Wolski took a total of one shift in the third period in Washington’s 3-2 loss to the Devils Thursday night. Part of the reason for that is because he doesn’t kill penalties and the Capitals were frequently playing short-handed. But even after Ilya Kovalchuk’s power-play goal gave New Jersey a lead, Oates shortened the bench, opting to play Eric Fehr and Matt Hendricks over Wolski. Earlier this week Wolski was asked about his scoring drought. “It’s tough; you never know why. It’s something that you want to work through,” Wolski said. “You don’t want to veer to far from the game plan. I think when you don’t score you want to start changing things because you’re not scoring but I think the best thing to do is to work through it, put in the effort and the results will come. I think you’ve just got to keep it together and really bare down.”
