Florida is 3-7 in shootouts.
"[Greiss] was outstanding," Trotz said. "They had a couple of posts, but if you're in perfect position that's all they can hit. He was outstanding in the shootout against them, pretty dynamic people. He was really good. He was calm. It was a hard game for him because the first period he didn't get any shots, he just stood there and watched for the most part. Got a few tough looks in the second, and then in the third they got the one and then he had to go in the shootout. All year in the shootout he's been outstanding."
Huberdeau scored, and Montembeault made 35 saves for the Panthers (36-32-13), who had won three in a row. Montembeault, making his 10th NHL start, also had his first NHL assist.
"He had to make some big saves," Panthers coach Bob Boughner said. "Goal-mouth scrambles where it was two and three at a time. I thought that was his best game he's played for us as a Panther so far, no doubt about it. He's had some good games, some really good games, but that one stands out for me."
Montembeault was making his first start since being pulled after giving up two goals on four shots in the first 4:21 of a 7-5 loss to the Toronto Maple Leafs on March 25.
"I was seeing the puck well," Montembeault said. "It was important for me to come back with a good performance. We did a good job, there was a lot of point shots for them."
Nelson made it 1-0 at 1:50 of the second when he one-timed Michael Dal Colle's pass across the middle.
Huberdeau tied it 1-1 at 12:45 of the third period on the power play on a breakaway after taking a two-line pass from defenseman Keith Yandle.
"Such a timely goal," Boughner said. "It was a great little design that we had on the entry on the power play. The guys executed it and he finished. I'd like to see one more [point] in the shootout, but it was a big goal for us."
