PITTSBURGH – Robin Lehner has a message for any player who wants to get physical with him in the crease: It only makes the Islanders goalie better.

Lehner stopped the last 32 shots he faced as the Islanders swept their first-round series against the Penguins with a 3-1 win in Game 4 Tuesday night at PPG Paints Arena.

The 6-4, 240-pound Lehner also had to be separated from fellow Swede Patric Hornqvist at 10:33 of the second period.

“Nah, it wouldn’t have crossed the line,” Lehner said. “I’m not dropping the gloves in the middle of the game. You know they’re frustrated, and there’s only so much I can take, too.”

Hornqvist was trying to establish position at the crease with Lehner trying to push him away, giving him some whacks on the leg with his goalie stick. The stick swings and shoving quickly escalated, with Lehner looking like he was ready to fight before linesman Jonny Murray separated him from the scrum.

Lehner received a two-minute slashing penalty, but Hornqvist received a double-minor for roughing.

They spoke genially during the postgame handshakes.

“I’m going to try and be a little more disciplined, too, the next time,” Lehner said. “It just fires me up and makes me better. So whatever team wants to do that to me, it just wakes me up.”

Remember those words

Islanders coach Barry Trotz led the Capitals to that franchise’s first Stanley Cup last season.

And when he was presented with his Cup ring before the Capitals’ 4-1 win at Barclays Center on Nov. 26, Trotz was allowed to address his former players in the visitors' dressing room.

“You’ll have to go through the Island, but you guys can do it again,” Trotz told the Capitals that night.

It very well may prove prescient as the Islanders await the winner of the Capitals-Hurricanes first-round series.

“If it happens to be Washington, what I said will be played forever on every newscast,” Trotz said.
