Madison Square Garden showed Game 4 of the ALCS during the Rangers-Penguins game

The Yankees' support stretches beyond the fans in the stands and the fans at home. That was apparent during their 6-4 win over the Astros in Game 4 of the American League Championship Series presented by Camping World. The Yanks can thank the New York Rangers for that.
On Tuesday night, at Madison Square Garden, the Rangers were hosting the Penguins. On the main screen atop the rink, they showed the Yankees' phenomenal bottom half of the eighth inning. The Aaron Judge double was displayed in front of the crowd which reacted when Jacoby Ellsbury scored. This was then followed by a Gary Sánchez double on a line drive to center field and Judge crossed the plate to bring in another run.  
As you can see, the crowd was beyond excited:

The Yankees scored four runs in the decisive inning.
We know the rest of the story, but it was a nice gesture to see the Rangers supporting the Yankees mid-game.
