Mrazek made a save on Trocheck and the puck bounced up and off the crossbar. Alex Vlasic couldn't clear it off the goal line as Kreider was coming into the area, and the puck went in off Kreider's right skate as he was trying to stop in the crease.
The call on the ice was a good goal, which was confirmed after video review by the NHL Situation Room to determine if there was a distinct kicking motion.
"By letter of the law if it's a stopping motion it's supposed to count," Rangers coach Peter Laviolette said. "It's got to be a kicking motion. Stopping is allowed, so I think they got it right."
Blackwell cut it to 2-1 at 17:03, capitalizing as New York was in the middle of a line change.
Jaycob Megna found Boris Katchouk with a stretch pass up the left side, and Blackwell had a step on K'Andre Miller. He received Katchouk’s pass between the circles, deked forehand-to-backhand and scored his first goal since Feb. 10.
"I saw our [defenseman] fire it up to the far blue line and [Katchouk] made a great play," Blackwell said. "He waited a little bit until the stick got out of the way and slid it over to me. I was lucky to find the back of the net for the first time in a long time."
Jacob Trouba pushed the lead to 3-1 at 1:31 of the third period with a sharp-angled shot from the right circle, and Jimmy Vesey scored 70 seconds later for the 4-1 final at 2:41.
"It was good, right out of the gate," Laviolette said of the Rangers' third period. "We talked about that because of the goal at the end of the second. I didn't like the line change. Now it's a 2-1 game, but I liked the fact that we came out with the right intent right away. We started playing fast, playing in their end, putting pucks at the net. Trouba's goal was a big goal, followed it up right away and kept it going."
