SALT LAKE CITY–Utah defeated Buffalo 5-2 for the second time in eight days to sweep the season series, improving to 5-1-0 at home.
The Utah Mammoth (9-7-0) returned to Delta Center for a two game homestand on Wednesday night, having played eight of their previous nine games on the road. Former Utah Hockey Club favorites Josh Doan and Michael Kesselring, who were traded to Buffalo in the offseason for JJ Peterka, were recognized on the Jumbotron for the visiting Sabres (5-6-4) who lost to the Mammoth 2-1 in overtime on their home ice a week ago.
Buffalo forward Isak Rosen gave the Sabres the early lead at 5:33 of the first period with his second goal of the season, a deflection, assisted by Jack Quinn and Bowen Byram. Buffalo netminder Colten Ellis turned away all 12 shots he faced in the frame, while Utah’s Karel Vejmelka stopped seven of eight.
Rosen hit the scoreboard again at 6:42 of the second period with a slap shot which got past Vejmelka, assisted by Noah Ostlund. Utah forward Nick DeSimone, a native of the Buffalo area, trimmed the deficit to 2-1 at 10:42 of the period with his first goal of the season, a slap shot one-timer on a carom off the boards which Michael Carcone had shot from behind the net, with the additional assist going to Nate Schmidt. As the buzzer sounded to end the period, Ellis had saved ten of 11 Mammoth shots while Vejmelka again turned away seven of eight.
Less than a minute into the third period, JJ Peterka tied things up against his former team, smashing a sweet snap shot past Ellis for his fifth goal of the season, assisted by John Marino and Mikhail Sergachev. Just a couple of minutes later Peterka fed a pass to Lawson Crouse who launched a sharp angle shot over the shoulder of Ellis to give Utah its first lead of the game, 3-2.
Jack McBain picked up the additional assist on Crouse’s fourth goal of the season. Halfway into the period, Mammoth forwards Clayton Keller and Nick Schmaltz battled hard for the puck in the offensive zone.
Keller came up with the puck behind the net and found Schmaltz in front who netted the third Utah goal in a ten minute span for his tenth of the season, giving the Mammoth a 4-2 lead. Keller has assisted on seven of Schmaltz’s goals this season.
With Ellis pulled for an extra attacker, Schmaltz returned the favor, feeding Keller the puck for an easy empty net goal, his seventh of the season, icing the game at 5-2 with 26.6 seconds remaining. Logan Cooley recorded an additional assist on the play. On the ensuing faceoff both teams dropped the gloves resulting in game misconduct penalties to Josh Dunne and Peyton Krebs of the Sabres, and Barrett Hayton of the Mammoth.
In the lively winning locker room, JJ Peterka commented on the team’s comeback. “I think just how much belief there is in each other. Never giving up. We know how good we can be offensively. We know even when we’re trailing, we can easily come back. So I think just the belief in each other here.” With regard to DeSimone’s goal, Peterka said, “It’s awesome, especially him being from Buffalo makes it even better. Since he came into the lineup, he has done a heck of a job for us. Played super solid. So, obviously, super nice to see him score.”
DeSimone weighed in on the team’s turnaround after surrendering the first two goals. “That obviously was not our best start. We stuck with it and kept trying to play our game. We kept working on it, and we fought through a little adversity, and then we found a couple of shifts in a row and got rewarded for it. It just kept rolling after that.” When asked what the team learned about themselves with the comeback, DeSimone added, “It is big for us to go through this fight of adversity and kind of claw our way back into one and end up getting a win. It is definitely a learning moment for us, and it shows a lot of maturity in our group.” Many considered his second period goal to be the turning point in the game, and DeSimone walked the media through what happened. “Bear (André Tourigny) called that time out, and we hit a reset button there. Everyone was trying to do the right thing and get us going, but for whatever reason, it just reset us. It’s fortunate enough that it goes in and gets us going. It could have been a hit; it could have been just getting a puck deep, just little things kept getting us going as well.”
Utah Mammoth Head Coach André Tourigny entered the media room with a bit of pep in his step. “I think we played good, I won’t say all game; obviously we could feel the nerves a little bit the first two periods. I think JJ Peterka broke the game down when he scored that big goal. From there, there was a boost of confidence and we knew we were playing well. I think that the tweak in the lines helped a little bit for everybody. I’m really happy about the way JJ responded in the third. (Lawson Crouse) and (Jack McBain) played unbelievable again. That’s about it.” Speaking of what contributed to the successful third period, Tourigny said, “We addressed it this week. One thing our team is really good at is defending. We defend with a lot of pace and we force opponents to execute quickly. That’s a strength of ours. Lately in the third period, we’ve not had the same pace and same pressure. That was allowing our opponents to execute and create offense. The last three games, more than 50% of the offense we gave up was in the third period–because we were trailing, chasing, not defending hard enough. Tonight, we gave up zero grade A and zero grade B (chances). We defended hard and we played good with the puck…Everybody was engaged. Everybody was detailed, resilient, relentless. That was fun to see.”
The Mammoth (10-7-0) wrap up their brief homestand on Friday night against the New York Islanders (8-6-2) before hitting the road again for a brief California swing through Anaheim and San Jose.
