Keller made it 2-0 at 13:53, and Schmaltz extended the lead to 3-0 at 2:50 of the second period. Maccelli, playing his second NHL game, pushed it to 4-0 at 12:35 off a Phil Kessel shot.
"There was a rebound right in front of the net and I saw the five-hole was open, and I tried to go backhand and it went in," Maccelli said.
Kelly made it 4-1 at 13:54, the first of three Ottawa goals in 2:12. Josh Norris made it 4-2 with a one-timer on the power play at 15:11, Kelly cut it to 4-3 at 16:06, and Alex Formenton tied it 4-4 at 56 seconds of the third.
"There were a lot of highs and lows, it was a fun game to play in, but in the end we're all disappointed," Kelly said.
NOTES: Schmaltz has scored 17 points (nine goals, eight assists) in his past nine games. His five assists tied a Coyotes/Jets record; the last player in their history to do it was Keith Tkachuk, the father of Senators forward Brady Tkachuk, on Feb. 23, 2001, for the Coyotes against the Buffalo Sabres. Schmaltz had four assists in the third period, one short of the Coyotes/Jets record for a period, set by Dale Hawerchuk for Winnipeg on March 6, 1984, against the Los Angeles Kings. … Arizona was 2-for-5 on the power play after it was 1-for-23 in its previous 11 games. … Coyotes forward Tyler Boyd played 20:07 after signing a two-year contract Saturday. … Arizona was 4-4-0 on an eight-game homestand. … Ottawa has lost the first three of a five-game road trip.
