Sidney Crosby wasn’t even aware of reaching yet another milestone. He’s simply locked in on helping the Pittsburgh Penguins make a 17th straight postseason appearance.

Jeff Carter had a pair of goals, Crosby scored on a nifty backhand shot in the second period to reach the 30-goal mark for an 11th season and the Penguins beat the Colorado Avalanche 5-2 on Wednesday night.

Crosby moved into a tie with Hall of Fame center Mario Lemieux for the most 30-goal seasons in Penguins history. Another milestone reached — it came as news to him.

“I think the most important thing for me is just try to be consistent, and if that reflects that, great,” said Crosby, who turns 36 in August.

Even more, Crosby is the first player in league history to post a 30-goal campaign at 18 years old and again when he was 35-plus, according to NHL Stats.

“It means I’ve been in the league for a while,” Crosby cracked. “That’s been the thing that’s driven me since since I got into the league — in your first year, you want to prove that you belong. Even at 35, I still think you want to prove you belong, because it is a younger league.”

Jake Guentzel also scored and Bryan Rust added an empty-net goal for the Penguins, who snapped a four-game slide and moved back into a wild-card spot in the East.

“It’s definitely a big one for us, for sure,” Guentzel said. “Defending champs, coming to their building, you know how good they are. Top to bottom, we defended hard, and that’s what we have to do at this time of the year.”
