Pitching in shirt sleeves

This is a phrase that Joe Castiglione uses on Red Sox radio when the weather starts getting warmer. It drives me crazy. He means to say the guy's pitching in short sleeves. The only shirts that don't have sleeves are tank tops, and long sleeves count as shirt sleeves, too!

My arm is killing me! It was healing nice, until I got my arm stuck in a rebound battle last night.

Got some Bang Tango playing on iTunes here at work. Anyone remember them?
