Good question. Does MTV's Rock and Jock Softball count?

Others that come to mind:

-There's the 1937 movie "GIrls Can Play" directed by Lambert Hillyer. "The Hollywood Post's sports writer, Jimmy Jones (Charles Quigley),

yearns to be a crime reporter, and thus looks for foul play on even the

most routine assignments. In writing a piece about a girl's softball

team, Jimmy discovers that their sponsor, Foy Harris (John Gallaudet),

is a notorious racketeer who has supposedly gone straight. Jimmy

suspects Foy is still up to no good. He begins hanging around the team

to do a bit of snooping, and also to be near the cute new pitcher, Ann

Casey."

-1980 movie "Squeeze Play: "

A male softball team is challenged by a female softball team to see who is best.

-And the 2005 movie "Beer League".

That's all I got. Any others I missed?

I had the same reaction! Thankfully I thought about it for a second before posting. I hadn't heard much about men's fastbitch softball so I wanted to see what I could find on YouTube. I found a pretty good video from the American Challenge Series in Oklahoma City that invited Men's Fastpitch teams from around the globe. Interesting stuff.
