Hayes then scored again to put the Penguins ahead 2-1 at 18:47. Anthony Mantha sent a no-look pass through his own legs from behind the net for Hayes low in the left circle, where he put a rising snap shot by Lyon glove side.
Kindel extended it to 3-1 at 7:44 of the second period, scoring bar down from the left circle on a 2-on-1.
Thompson scored on the power play to cut it to 3-2 at 1:55 of the third period, lifting a wrist shot short side from the goal line over Silovs’ right shoulder.
“Obviously, want to continue to get better and climb in the standings,” Thompson said. “Tonight was an opportunity to do that. It’s tough when you let something like that slip.
“That said, we still have a lot of hockey left and can’t let it affect the mind moving forward. We’ve done a great job all year just turning the page and refocusing, whether it’s a win or loss, and getting ready for the next challenge.”
Tommy Novak scored from in front to make it 4-2 at 15:33, knocking the rebound of Egor Chinakhov’s point shot past Lyon’s glove.
Kindel scored a short-handed, empty-net goal at 19:46 for the 5-2 final.
“A big penalty kill by the rest of the guys, some big blocks, and then I had the easy part,” Kindel said. “There’s a lot that goes into that. A lot of gutsy plays by the guys, so it’s a great team win.”
NOTES: Hayes is the third player in Penguins history to score multiple goals in his NHL debut, joining Jake Guentzel (two goals on Nov. 21, 2016) and Rob Brown (two goals on Oct. 21, 1987). He is also the 12th undrafted player in League history to score multiple goals in his debut (since the NHL Draft began in 1963). … Hayes and Kindel are the sixth pair of Penguins rookies to each score multiple goals in the same game.
