Oscar Lindberg scored two goals and Henrik Lundqvist made 22 saves as the New York Rangers beat the Ottawa Senators 4-1 Thursday night to level their Eastern Conference semifinal series at two games each. Chris Kreider and Nick Holden also scored and Tanner Glass added two assists for the Rangers, who have won four consecutive home games this postseason. Kyle Turris scored for Ottawa, and Craig Anderson made 17 saves before being replaced by Mike Condon for the third period. Condon finished with nine stops. Senators star defenseman Erik Karlsson also left the game after the second period with an injury. Karlsson played during the first round with two microfractures in one of his feet from blocking a shot late in the regular season. Game 5 is Saturday at Ottawa. Lundqvist has stopped 48 of his past 50 shots after allowing six goals in the Senators' double-overtime win in Game 2. Lindberg scored both of the Rangers' second-period goals. Glass, playing his second consecutive game, blocked Ben Harpur's shot and Michael Grabner grabbed the loose puck and broke in with Lindberg, who scored on a one-timer at 2:01. Glass also helped set up Lindberg's next goal. He outworked Senators defenseman Cody Ceci for the puck behind the Ottawa net and sent it to the boards. J.T. Miller grabbed the loose puck and passed to Lindberg at the point for a 3-0 lead at 15:54. Lindberg also scored the Rangers' final goal in their Game 3 win. Kreider made it 4-0 with a power-play goal at 10:45 of the third. Turris scored at 13:34, but the Senators had trouble generating sustained pressure against Lundqvist and were sloppy with the puck at times. For the second consecutive game, the Rangers controlled the first period. In Game 3, they scored the first two goals and outshot Ottawa 15-5. On Thursday, they outshot the Senators 11-7 and opened the scoring again. Holden led a breakout from the defensive zone and sent a pass to Kevin Hayes at center ice. Hayes passed back to Holden along the left wing and he broke in toward the net and beat Anderson with a wrist shot that went over his right pad at 14:04. The Rangers have scored the first goal in each game of the series. Crosby back on ice Superstar forward Sidney Crosby skated Thursday with his Pittsburgh Penguin teammates for the first time since suffering a concussion from an illegal cross-check to the head. "He's in the process of rehabbing," Penguins coach Mike Sullivan said of Crosby, who has won two Olympic gold medals in 2010 and 2014 with Canada. "We'll just leave it at that. It's a day-to-day process. We're taking each day as it comes." The 29-year-old Penguins captain was injured in a playoff game on Monday when American defenceman Matt Niskanen raised his stick and slammed it into the side of Crosby's head as he was off balance in front of net after being clipped moments earlier by the stick of Alex Ovechkin. Niskanen was given a five-minute major for cross-checking and a game misconduct. Niskanen is a former teammate of Crosby's on the Penguins. Crosby missed the first six contests of this season with a concussion. Pittsburgh posted a 3-2 victory in game four on Wednesday to seize a 3-1 edge in the NHL playoff quarter-final series. The Penguins can eliminate the Capitals for the second straight year with a win in game five Saturday. — Agencies
