DeSmith started Game 1 but left in the second overtime after sustaining a core muscle injury and underwent surgery May 6. Domingue replaced DeSmith and made 17 saves in the Penguins' 4-3 triple-overtime win. He went 3-3 with a 3.65 GAA and .898 save percentage in five starts.
"Sometimes we had leads, sometimes they had leads. … It's hockey," Penguins coach Mike Sullivan said. "They're a balanced team. They've got a dynamic power play. They've got one of the best goalies in the league. … Give the Rangers credit. Congratulations to them. They're a heck of a hockey team. It was a hard-fought series."
Zibanejad tied the game 3-3 at 14:15 of the third period, taking a pass from Copp and scoring top shelf from the right circle.
"They find a way. I'm really proud of them," Rangers coach Gerard Gallant said. "I knew tonight was going to be a battle. We talked about the seventh being game at home. We fell behind at home but found a way to battle back."
Rodrigues gave the Penguins a 3-2 lead with a shorthanded goal at 17:24 of the second period, scoring on a breakaway just as a penalty to Bryan Rust for cross-checking Rangers defenseman Jacob Trouba was expiring.
Guentzel made it 2-1 at 10:18 with a power-play goal. The Penguins forward was atop the crease and kicked the pass from Rust up in the air before batting the puck into the net. The goal was reviewed for a high stick, but the call on the ice was confirmed.
"It's disappointing," Guentzel said. "I mean, we're right there. We put ourselves in a good spot being up 3-1 (in the series). It's just disappointing to think about, that we had a lead in each game and kind of gave that way. This is an amazing group, we believed the whole time and it just didn't go our way."
Miller tied it 1:05 later to make it 2-2 when his point shot went off Penguins forward Jeff Carter and defenseman Mike Matheson and past Jarry at 11:23.
Kreider gave the Rangers a 1-0 lead at 7:36 of the first period, finishing a 2-on-1 with a one-timer and Danton Heinen tied it 1-1 with a power-play goal at 18:51. The NHL situation room stopped play after determining that the puck completely crossed the goal line.
NOTES: Kreider tied Mark Messier for the second most playoff goals in Rangers history (29) behind Rod Gilbert (34), and tied Anders Hedberg for the 10th most playoff points in Rangers history (46). … Penguins forward Rickard Rakell had four shots on goal and one hit after missing five games with a lower-body injury. … Crosby tied Jaromir Jagr for fifth on the NHL's all-time playoff points list (201). The assist, the 130th of his career, moved Crosby into sole possession of fifth on the NHL's all-time assist list. … Rangers defenseman Adam Fox (10 points; three goals, seven assists) became the fourth defenseman in NHL history with at least one point in all seven games of a series, joining Miro Heiskanen (Dallas Stars, 2020 Stanley Cup Second Round), Larry Murphy (Penguins, 1995 Eastern Conference Quarterfinals), and Paul Reinhart (Calgary Flames, 1984 Smythe Division Finals). Fox is the first skater in Rangers' history to accomplish the feat. … Guentzel had eight goals, the most by a player in a single round since Crosby and Alex Ovechkin each had eight in the 2009 Eastern Conference Semifinals. … New York is 8-1 at home in Game 7s.
