"I think every team in the League, to be honest, has a star, and he came through in the clutch today," Allen said of Tarasenko. "If he gets his chances like that, like most guys do in the League, he'll bury them. He's playing well right now."
Andrew Ladd scored with 6:56 left in the third period and Anders Lee tied the game with 59.2 seconds remaining for New York (1-1-1). Thomas Greiss made 33 saves.

"[Allen] was seeing everything tonight," Lee said. "He controlled all his rebounds and they were playing tough in front. When he's seeing the puck like that, it's tough to get opportunities and get those second chances."
After scoring midway through the second period, Tarasenko made it 2-0 with a power-play goal at 15:34. With Anthony Beauvillier in the box for high sticking, Tarasenko took a pass from Jaden Schwartz and beat Greiss with a wrist shot from the right circle. The Islanders challenged the Blues were offside prior to the goal, but the call stood after video review and New York was assessed a delay of game penalty.
