Brandon Sutter scored a short-handed goal to break a second-period tie, and the Pittsburgh Penguins moved within one win of the Eastern Conference finals with a 4-2 victory over the host New York Rangers on Wednesday night.
Pittsburgh, which has won three straight following a series-opening loss, can advance with a Game 5 victory at home Friday night.
"We know they are going to be desperate," Penguins captain Sidney Crosby said. "They have a lot of depth, and a lot of guys that can create things, so we have to have the same mentality that we had."
Evgeni Malkin scored at 2:31 of the first period, and Jussi Jokinen made it 3-1 at 7:02 of the third before the teams traded late goals.
Jokinen scored with a flip shot that struck the right leg of Rangers defenseman Marc Staal and bounded past goalie Henrik Lundqvist.
The only negative for the Penguins was that Marc-Andre Fleury allowed a goal for the first time in three games. Carl Hagelin's tying tally in the second period was the Rangers' first goal in 145 minutes, 30 seconds of playing time.
Mats Zuccarello backhanded in a goal with 6:53 left to cut the Rangers' deficit to 3-2, but Chris Kunitz restored Pittsburgh's two-goal edge 57 seconds later.
The weary Rangers played for the sixth time in nine nights, and not even a full day of rest on Tuesday or the return of forward Chris Kreider helped them. Kreider played for the first time since breaking his left hand a month ago.
Blues: Coach Ken Hitchcock's contract was extended through next season. Hitchcock led the Blues to a franchise-record 52 victories this season and has taken them to the playoffs all three of his seasons.
Flyers: Ron Hextall was named general manager to replace Paul Holmgren, who was elevated to president. Hextall is Philadelphia's all-time winningest goalie and served as assistant G.M. last year.
