What happened: Artturi Lehkonen scored 24 seconds into the second period to pull even with the Penguins at 2-2. He earlier converted a feed from Nathan MacKinnon to cut Pittsburgh's initial lead in half.

Why it matters: The two-goal effort erases an early two-goal deficit and puts Lehkonen one goal shy of a hat trick with nearly two full periods remaining.

What to watch: Lehkonen has the remainder of the second and third periods to pursue his third goal as both clubs play from a 2-2 tie.
