The 20-year-old forward, who had one goal in the final 19 regular-season games, had the only goal in the 2-1 loss. Captain Blake Wheeler said that goal, in addition to the fire and spark Laine showed all night, is a good thing going into Game 2 of the best-of-7 series at Bell MTS Place on Friday (9:30 p.m. ET; CNBC, SN, TVAS, FS-MW).
"He's a goal-scorer," Wheeler said. "That's what he gets out of bed to do every day, score goals. And when you're not scoring goals, it's tough. So that was probably the best way the series could have started for us, get him on the board and feeling good."

Laine, who scored 36 goals in his rookie season of 2016-17, and 44 in 2017-18, scored 30 this season, his final goal coming March 25.
But he gave the Jets the lead in Game 1 with a shot that went off the right post and in at 13:28 of the first period.
The scoring touch he displayed with 18 goals in November -- including five in one game against the Blues on Nov. 24 -- returned.
"It felt good to score, to be honest," said Laine, who had three shots on goal and hit a post playing 17:29 of ice time. "It was a tough way to end the regular season, but it's gone now, and now it's playoff time and it's a whole different chapter. It felt great."
Jets coach Paul Maurice said what has encouraged him most about Laine is not the fire or his goal in Game 1, rather the improvement the No. 2 pick in the 2016 NHL Draft has made to other areas of his game.
