Islanders 5-4 Panthers
The 18-year-old Schaefer had already broken the record for most goals by a rookie defenceman under the age of 20. Now, after scoring two goals in the win of the Panthers, he now needs just four more to surpass Brian Leetch (1988-1989) for the most ever by a rookie defenceman of any age.
Schaefer now has 20 goals and 24 assists through 61 games this season. Teammate Anders Lee sent home the game-winner, his 14th goal of the season, with just 32 seconds left in the final period as the Islanders have now won eight of their last 10 games, improving to 35-21-5.
Meanwhile, Florida fell to 30-27-3.
Penguins 5-0 Golden Knights
Despite both teams putting up 22 shots on net, the Penguins came away with the shutout win.

With five minutes to go in the game, Justin Brazeau (16) added the final tally as the Penguins improved to 31-15-13. Goalie Arturs Silovs recorded his second career shutout.
Vegas fell to 28-18-14 and will wait to hear a diagnosis on star Mark Stone after he left the game with an injury.
Blackhawks 4-0 Mammoth
It took five years, but goalie Arvid Soderblom finally recorded his first career shutout after making 22 saves against the Mammoth to help his Blackhawks improve to 23-28-9.
Teuvo Teravainen (12) scored two of Chicago's goals, with the first coming on a power play in the first period to go up 1-0, and the second on a short-handed to goal for the game's final score. It's his first multi-goal game of the season and his first since January 10, 2025.
Nick Foligno (3) and Landon Slaggert (3) scored the others, forcing the Mammoth to fall to 31-25-4.
Sharks 2-1 Jets
After outshooting the Jets 33-28, the Sharks completed the comeback after Morgan Barron (8) put Winnipeg up 1-0 in the first period.
