"I was joking that if me, [Tyler] Johnson and Killorn were on a 3-on-1, who would want the puck, and I would probably be your last option," Koekkoek said. "I was looking for [Tyler] back door, but the goalie was right on me, so a little fake and then he opened up his five-hole."
Hunwick made it 5-4 when he scored on the rebound of a shot by Greg McKegg at 10:01 of the third period.
Sheary made it 3-2 at 8:58 of the second period when he broke into the zone off a pass from Chad Ruhwedel and beat Vasilevskiy with a wrist shot high on the stick side. Kucherov gave the Lightning a 4-2 lead at 9:49, and Rust scored a power-play goal at 14:24 on the rebound of a shot by Guentzel to make it 4-3.
Koekkoek's first NHL goal gave the Lightning a 1-0 lead at 6:07 of the first period. His slap shot from the point hit the stick of Penguins forward Tom Kuhnhackl and trickled past Niemi. The 23-year-old defenseman was playing his 43rd NHL game.
