They won 2-1 in Game 4 and 2-0 in Game 5, when Neuvirth made 44 saves in Washington.
"He's a fighter," defenseman Shayne Gostisbehere said. "He finds a way to win games and make big saves at the right time. We believe in him. He's the same guy as two years ago, when he came in against Washington. He almost saved the series and made us win. It's the type of effort you need and we'll need some more from him."
Neuvirth missed the first three games against the Penguins because he was nursing the lower-body injury he sustained in a 2-1 win against the Colorado Avalanche on March 28. That was his first appearance since Feb. 18, when he also sustained a lower-body injury.
But Neuvirth surprisingly dressed as the backup to Brian Elliott in Game 4 instead of Petr Mrazek. He was forced into action in the second period after Elliott allowed three goals on 17 shots.
Neuvirth gave up two on 13 shots in what turned into a 5-0 loss, but getting into the game was enough to convince Hakstol that he was the right goalie to start Game 5.
"We just felt that [Neuvirth] has looked sharp in practice," Hakstol said. "He went in the other night and he got some game action, so even though he hasn't been in the net a lot he did have an opportunity to get into this series. In talking it through with Kim Dillabaugh, our goaltending coach, he was the right choice for [Game 5]. He's done it all year for us. At the right time, he's come in and played a big game for our hockey team and we needed that from him."
