Henrik Lundqvist’s right eye is just fine, thanks.

So, too, are the Rangers with their franchise goaltender back to looking like the foundation for New York’s near annual deep postseason run.

Three days removed from a freakish run-in between his face and teammate Marc Staal’s stick, Lundqvist looked like his steady self while making 29 saves and the Rangers took advantage of some sloppy defensive play by host Pittsburgh in a 4-2 victory on Saturday that evened their Eastern Conference quarterfinal series at 1-1.

Lundqvist sat out the final two periods of Game 1 after Staal’s stick made its way through the goaltender’s cage, scraping Lundqvist’s right eye.

He saw a specialist on Thursday, practiced on Friday, and spent three periods on Saturday doing what he always seems to do this time of year.

‘‘When you know there’s nothing wrong with the eye, you know you can just go out there and just push yourself and whatever is feeling uncomfortable, you don’t really think about it when the game starts,’’ Lundqvist said. ‘‘You just want to be out there and you’re very determined.’’

Lundqvist kept the surging Penguins — boosted by the return of star center Evgeni Malkin — at bay for most of the first 30 minutes, then saw his team pounce when Pittsburgh went through the kind of lull it largely avoided while ending the regular season with a 14-2 burst.

Keith Yandle and Derick Brassard scored 18 seconds apart in the second to give the Rangers the lead.

Mats Zuccarello and Chris Kreider piled on later as New York improved to 6-2 since the start of the 2014 playoffs in the game immediately following a loss.

J.T. Miller added three assists as the Rangers handed Pittsburgh just its third loss since March 6.

Game 3 is Tuesday in New York.

Pittsburgh’s Phil Kessel scored his first two playoff goals in three years. Backup goaltender Jeff Zatkoff made 24 stops while making a second consecutive start in place of injured Marc-Andre Fleury.

Malkin finished with an assist in 18:57 of ice time but looked reticent to shoot while toggling between lines, including an occasional pairing with Sidney Crosby.

‘‘Everything is fine but I need a little bit more confidence,’’ Malkin said. ‘‘It’s pretty hard but I'm fine. I'm still positive.’’

Capitals 4, Flyers 1 — Washington’s Braden Holtby made 41 saves, Philadelphia’s Steve Mason gave up a goal from 101 feet away, and Alex Ovechkin scored on the power play as the host Capitals took a 2-0 series lead in the Eastern Conference quarterfinal matchup.

Ovechkin’s 37th Stanley Cup playoff goal was as predictable as Jason Chimera’s goal from beyond the red line was unexpected. Mason whiffed at the puck on what turned out to be the winner.

The Flyers outshot the Capitals, 42-23, and dominated for much of the game, but came up empty as John Carlson scored his second power-play goal in as many games and Nicklas Backstrom added one at even strength late.

Jake Voracek scored the Flyers’ only goal.

The series shifts to Philadelphia for Game 3 on Monday night.

Mason did the splits to stop a point-blank range early in the second period and was slow to get up. He remained in the game, but less than a minute later made the mistake that will be shown on bad-goal blooper reels for decades.

After Karl Alzner backhanded the puck from his goal line, Chimera tipped it from the Capitals’ side of the red line. It slid five-hole on Mason, who wrenched his head back in dismay.

Stars 2, Wild 1 — Antoine Roussel scored from behind the net and Jamie Benn had an unassisted goal as host Dallas built a 2-0 lead in the Western Conference quarterfinals.

The Stars scored first on Roussel’s strange goal about four minutes into the second period, when the puck ricocheted off the skates of Ales Hemskey and Roussel without either getting a stick on it.

Benn scored on a breakaway that he ended with a backhand to make it 2-0 with 9:37 left in the game. Tyler Seguin returned for Dallas after missing 11 games because of a slight cut of his left Achilles suffered March 17. He had one shot in 15:40 of ice time.

Minnesota’s Marco Scandella scored on a slap shot from well above the left circle with 7:18 left.

The series shifts to Minnesota for Game 3 on Monday night.
