Murray is week to week because of a lower-body injury sustained in a crease collision against the Philadelphia Flyers on Monday. In his place steps Jarry, who started the season as the No. 1 with Wilkes-Barre/Scranton, the Penguins' American Hockey League affiliate. He was called up Oct. 30, after the Penguins waived backup goalie Antti Niemi on Oct. 23.

Pittsburgh Penguins goaltender Matt Murray is out of the lineup because of an injury, but his replacement, Tristan Jarry, shares many characteristics with him.

The Penguins (13-10-3) are fourth in the Metropolitan Division. They play at the Buffalo Sabres on Friday (7 p.m. ET; SN, TVA Sports, MSG-B, ATTSN-P, NHL.TV) to open a back-to-back set against them.

The similarities between the paths to the NHL for Murray and Jarry are numerous.

Selected one year and one round apart by the Penguins in the NHL Draft, Murray (No. 83 in 2012) and Jarry (No. 44 in 2013) signed entry-level contracts with the Penguins the same day in 2013, and played with Wilkes-Barre/Scranton in 2015-16.

Murray finished that season by winning the Stanley Cup after getting called up because of an injury to starter Marc-Andre Fleury, and Murray won the Cup again last season, cementing his status as the Penguins' No. 1. Murray's injury gives Jarry, who practiced with the Penguins' extra players during each of the Cup runs, a chance to secure his own NHL future.

The key for Jarry, who is 2-0-2 with a .907 save percentage in four NHL games this season, will be not trying to do too much to match Murray's early success as a starter.

"You are in a position where you are now the starter and your mindset immediately changes from being Robin to being Batman and that's part of the maturity process," said Mike Buckley, who was hired as Pittsburgh's goaltending development coach Sept. 30, 2013, the same day Murray and Jarry signed their first NHL contracts, and is in his first season as Penguins goaltending coach. "You've got to be authentic to who you are and what makes you successful as a goalie, understand your strengths and weaknesses, and keep playing your game."

The temptation to try to do more is common when a goalie moves up a level or into a bigger role, but the reality is goaltenders can't dictate or control what happens in front of them. Trying to force things rarely works in a position that most often is about letting the puck come to you.

Buckley saw Jarry trying to do more in some of his puck-handling decisions shortly after the Penguins called him up. Murray is good at managing the puck by settling it, reading the forecheck and making the simple choice. Jarry is more likely to try to make a play with the puck, perhaps catching the other team on a line change.

"[Jarry] is a very good puck-handler, and any opportunity he has to play the puck I want him to play it. But it has to be a smart decision and not a forced decision," Buckley said. "That's the thing that comes out right away is I've seen him try to make a couple forced plays, try to do too much. That's been our motto the last few games here is just keeping it simple, right down to the preparation for each game and the drills we are working on, just really simple stuff."

The Penguins aren't worried about Jarry trying to play like Murray, however. As well as the two of them get along off the ice, there are differences in their personalities and how they play on it.

Jarry's masks always feature the characters from "Tom and Jerry" as a play on his name, but his personality runs counter to the frantic cat-chases-mouse kids cartoon and is better reflected in his nickname among the Penguins, Casual Jarry.

He lived up to it after Murray was injured Monday.

"No warmup, doesn't skate around, doesn't move," Buckley said. "Tristan just skates into the crease and throws his arm over the crossbar. He's more relaxed. Matt is really intense."

Jarry's style on the ice is more active, with movement and flow Buckley characterizes positively as a bit old-school. There is less consistency and predictability, and more improvisation, in Jarry's save selections compared to the more calculated Murray. For Jarry, it's part of playing to strengths he traces back to lessons learned from his first goaltending coach while growing up in the suburbs of Vancouver.

"You have to trust your foundation and trust what you grew up with, and I think a big thing for me growing up was skating," Jarry said. "You always want to be the best skater."

Jarry's skating foundation is at the core of his old-school flow. It is the perfect style for him, Buckley said, because it requires better reads than from those goalies who play a more technical, position-based style.

Jarry has found it easier to make those reads in the NHL.

"Guys are in the right place at the right time," Jarry said. "You have to trust your instincts and trust your reads, but they are in the right position. You are in the best league in the world with the best players in the world, so it's harder but easier to adapt at the same time."

Murray certainly made it look easy when he got his first shot in the NHL.

Jarry will try to do the same; just not too hard.
