Oddly, the headline on ESPN.com to the story via my portable device referred to a blowup with a radio host, but when I read through the whole story, it didn't explain.
But this from NBC 10 does.
"Manuel peppered the radio host with curse words throughout the confrontation, which did not end in his office. Shortly afterward, another altercation broke out in the Phillies’ locker room, where Manuel yelled, “I’ve been growed up. I grew up a long f**king time ago. What’s it to you, anyway?” Locker room staffers ushered an agitated Manuel out of the room...
... and NBC 10 caught it all on tape."
