That lead held through most of the third period, and the game looked all but over when Eichel drew a holding call against Kevin Shattenkirk to give Buffalo its sixth power play with less than six minutes remaining. Then Scottie Upshall intercepted a pass and sped to beat Lehner on a shorthanded breakaway - just the first shorthanded goal scored by the Blues all season and the second allowed by the Sabres - to bring the Blues within one.
If the people at KeyBank Center were biting their nails after Upshall's goal, they might have taken off an entire finger when Lehner was called for tripping Alexander Steen with 1:12 remaining. Lehner disagreed with the call - he said Steen had skated through his crease, a claim supported by video evidence - but it gave the Blues a 6-on-4 advantage once they pulled Allen nonetheless.
The Sabres came up with some key blocks on the ensuing penalty kill, however, and a broken stick on a Tarasenko shot all but ended the Blues' comeback hopes. Lehner exhaled with a fist pump at the sound of the final horn.
"It wasn't the perfect third, but when you win the game that's all you can ask for," O'Reilly said.
While their competitors do hold games in hand, the win brought the Sabres within one point of the second wild card berth in the Eastern Conference at game's end. (Toronto, currently in that spot, will have a chance to restore their three-point lead on Saturday night.)
"It's good. We want to keep climbing but we don't want to be looking at that board too much. We just want to keep looking toward the next game," O'Reilly said. "We've got Chicago coming in and, again, that's a very skilled team that has found ways to win games and it's not going to be easy. That's our focus now.
"We're not satisfied at all. We're happy to get the points, but we're going to do a bit of reflection, adjust a couple things and get ready."
