Derick Brassard was raised in Canada and spent nearly six seasons playing in Columbus, but he was born for Broadway. Playing in only his fourth career playoff game, the 25-year-old center, who was traded to the Rangers on April 3 as part of the deal for Marian Gaborik, had his second straight sensational game. He recorded two assists in a 4-3 win last night over the Capitals, which sends the first-round series back to Washington tied at two. On Monday, Brassard tied a Rangers record with three points in his Madison Square Garden playoff debut. “I’m a guy with a lot of passion and you can say that it came back when I got traded to New York,” Brassard said last night in the locker room, while sporting the team’s Broadway hat. “I’m having fun. They’ve showed a lot of confidence in me and I’m just trying to help the team. I know I can bring some offense. “We have a lot of talent on this team and that’s why I’m really excited. We can do a lot of damage and I want to be part of it.” Brassard said after Tuesday’s practice he believed the offensive momentum from Game 3 would carry over into Game 4. He made sure his prophecy came true, beginning with a cross-ice pass to Carl Hagelin, who gave the Rangers a 2-0 lead with a rising slap shot midway through the second period. Then, with the team’s inept power play taking the ice to start the third period — 1-for-16 in the series at that point — Brassard slipped a beautiful backhand through the middle of the zone and through two defenders out to Dan Girardi at the point, who put the Rangers back in front, 3-2, less than one minute into the third period. “He’s fun to have in the room and he’s obviously making a lot of plays,” Hagelin said of Brassard. “He’s a skill-guy with speed. You’re always going to welcome a guy like that.”
