Does the “Phans of Philly” group have any money left after they bought I-95 billboard space to mock Sidney Crosby?

If they do, hopefully they buy similar billboard ad placement somewhere between Pittsburgh International Airport and PPG Paints Arena. Maybe the Penguins captain will see the signs on the way into town, and he’ll be just as motivated to stick it to the Flyers again as he was Saturday night.

After being immersed among frothing Flyers fans for two straight days off in Philadelphia following his Game 3 embellishment penalty and a 3-0 playoff deficit, Crosby did what he normally does in that city.

He took the cross-state hate and shoved it right back in the faces of the fans and the opposing players, leading the Penguins to a 4-2 win. The victory kept the Penguins’ season alive and pushed the series back to Pittsburgh for Game 5 on Monday night.

On a first-period power play, the 38-year-old center scored his 16th career playoff goal against Philadelphia, the most by any player against the Flyers in their franchise’s history.

He also registered an assist with some fancy footwork, stellar wall-play and a great screen on a goal by Kris Letang.

Then Crosby punctuated the win at the game’s final horn by burying Philadelphia’s Travis Sanheim with a hit near the boards. The former Canadian Olympic teammates have been locked in a nasty battle throughout the series, and Crosby took a pound of flesh off the ice with him to set up Game 5.

“The way we played, a lot of guys contributing, generated really good chances and we looked more like ourselves,” Crosby said on SportsNet Pittsburgh after the win.

Crosby was far from perfect. He was under 50% in the faceoff circle for a third straight game (8-13). He made a bad turnover on a power play. His line was on the ice for Philadelphia’s second goal.

The Pens weren’t a complete Picasso either. As a team, they lost the battle in the faceoff circle again, 31-24. The power play gave up shorthanded looks once more. Anthony Mantha found his way to the penalty box again. They got baited into two more retaliation penalties, and they stumbled into a too-many-men-on-the-ice penalty.

But it was definitely Crosby’s best performance of the series. He looked more like himself and was impactful. But that 180-degree turn for No. 87 wasn’t the only reason why the Penguins were finally able to turn the tables.

• They built on a lead. After scoring the first goal at 14:24 of the first period, the Pens held the advantage until intermission. Then Rickard Rakell scored 63 seconds into the second period. It was the team’s first two-goal cushion in the series.

• Pittsburgh had the better goalie on the night. That’s not a knock on Stuart Skinner. He was quite good in Game 1 and Game 2, making numerous saves that kept the Pens close in those contests.

But he wasn’t as sharp in Game 3 en route to a 5-2 loss, so coach Dan Muse made a change to Artus Silovs.

The Latvian netminder answered the call. Silovs stopped 28 of 30 shots, including a few top-notch saves. It was his first start since April 11.

“You know, it’s an exciting opportunity. The playoffs are the most fun you can ever have,” Silovs said. “We’ve been waiting for a whole season to get at this point. Just enjoying every minute of it.”

Conversely, Flyers netminder Dan Vladar had his worst game of the series, yielding three goals on 20 shots, including a puckhandling gaffe that set up Rakell’s goal.

Prior to Saturday night, he was crisp and clean in all three games.

• The penalty kill was perfect on three attempts. It had allowed two power play goals in Game 3.

• Muse’s team posted two even-strength goals and scored into an empty net. They had just one even-strength goal in the previous three games.

“I thought we did a better job,” Muse said. “I think there’s another level that we can continue to get to. But I think we just played more whistle-to-whistle. I thought our overall decisions were better as we navigated through the neutral zone. As we’ve done all year, we’ll continue to look at the things that that we like from this game and look to carry them on.”

Maybe it wasn’t the billboard. Maybe these Penguins realized they couldn’t lose on World Penguin Day. The day of awareness aims to teach people about the importance of these birds in the ecosystem, especially the 10 species currently endangered.

The Pittsburgh species kept itself from becoming extinct for at least one more game. How long they can avoid extermination may depend on how long their captain can keep swimming in the fountain of youth he apparently rediscovered Saturday night.
