Los Angeles played the second of a back to back following a 4-3 overtime win against the Calgary Flames on Thursday, and went to overtime for the fourth time in five games.
"I thought it was a gutsy point by our team," Kings coach Todd McLellan said. "Our gas tanks were running low. … There was a lot of clogging up of the neutral zone by both teams and there wasn't a lot of free play. … We settled in and did a lot of things we wanted to do, but we just couldn't find that net."
Schmaltz gave the Coyotes a 1-0 lead at 9:45 of the first period on the power play, scoring eight seconds into a two-man advantage. Clayton Keller's seam pass following a face-off win found Schmaltz open backdoor at the left post.
"That [win] was the result of the way we played," Arizona coach Andre Tourigny said. "I liked our composure, our resilience. … They had won their last four, but we were stingy defensively and found a way to score a big goal."
Arizona had each of the first three power plays but couldn't score on the next two, and finished 1-for-6 with the man-advantage.
"I think on the 5-on-3 we could adjust a little bit and do a better job there," McLellan said. "They scored quite quickly, and we still had a full minute-and-a-half or whatever [on the penalty kill], so killing that was important to not go down 2-0."
Iafallo tied it 1-1 at 11:54 of the second period with a one-timer from the right point on the Kings' first power play.
"I was just trying to shoot the puck, to be honest, got a screen and [Sean Durzi] made a nice pass and I'm just trying to get a good shot in there," Iafallo said.
Iafallo replaced injured forward Arthur Kaliyev (undisclosed) on Los Angeles' second power-play unit.
"Without Arthur that hole needs to be filled, and I've seen Alex one-time a lot of pucks in practice," McLellan said. "He's got that skill set and he fits that spot pretty good."
