Philadelphia sports fans are known for their passion—and their honesty. So when a handful of Phillies players showed up at the Flyers' playoff game on Wednesday night, they got an earful from the home crowd.

With their own game postponed due to weather, stars like Trea Turner, Kyle Schwarber, JT Realmuto, and Jesus Luzardo headed to Xfinity Live! Arena to cheer on the Flyers in their playoff matchup against the Pittsburgh Penguins. The Flyers delivered a win, advancing to the second round. But when the Jumbotron panned to the Phillies' section during the third period, the crowd's reaction was anything but warm.

Booing echoed through the arena.

"That's awful—they never should have been shown on the Jumbotron," one fan said. Another added, "Lack of effort will get you booed all the time in Philly, and this Phillies team plays dead. The Flyers play hard every shift."

The harsh reception reflects a tough reality for the Phillies this season. Sitting at 11-19, they're second-to-last in the National League standings—only ahead of the New York Mets. A brutal 10-game losing streak earlier this month marked the team's longest since 1999, and the frustration is clearly spilling over into the stands.

Star Bryce Harper addressed the slump on April 24, saying, "Yeah, it's not great. Obviously, it's not the spot where we want to be."

In Philadelphia, where sports loyalty runs deep, patience wears thin when effort appears lacking. For the Phillies, winning back the crowd will take more than just showing up to support the city's other teams—it will take turning their season around on the diamond.
