Big fire in Philly?

Was watching the Phillies-Mets game today, and sometime around the sixth inning they showed a huge column of smoke off in the distance. It looked like a huge fire, but something happened in the game before they mentioned it and it was never shown or brought up again that I can remember.
Also looked on Philly.com and a couple of TV stations' web sites and didn't see anything. Anybody amongst the Philly or South Jersey SportsJournalists.com crowd see or hear anything about this today?

 

There are weird, huge smokestack things with open flames down in that part of Philly. I don't know what they arem but I've never seen them in any other place. That might have been what you saw.

 

That's probably from the oil refinery. There's a Sunoco (I believe) oil refinery not far from the stadium.

 

Back in 1974, there was a huge fire on the Philly docks that was caught on live TV during a World Football League game. Since it was the WFL, more people saw the fire in person than on TV.

 

This didn't look like a refinery or smokestack. It wasn't like the Oakland wildfire back in 1994 that they were showing during a 49ers game, but it was definitely bigger than a smokestack.
