Greiss, who made 14 saves in the first period, preserved the one-goal lead at 7:21 of the second during a penalty kill when he stretched across his crease to make a right pad save against Barkov. It was one of four saves while Jordan Eberle served a slashing penalty.
"I mean, what more can you say," Barzal said of Greiss, who has won each of his past six starts and has a 1.88 goals-against average and .942 save percentage. "His save percentage and goals-against average has been right up there at the top of the League. He had Vezina numbers last year, and again this year he's been doing the same thing."
Evgenii Dadonov had a chance to at 11:40 of the second, but his wrist shot from point-blank range hit the crossbar. Eberle then helped Greiss moments later when he sprawled out in the crease to block Brett Connolly's shot.
"You just do your best [Greiss] impression trying to make a save," said Eberle, who played for the first time since Oct. 12 because of a lower-body injury. "[Greiss] was, I think, the main reason we won today. He made some outstanding saves. Full credit to him."
