It's called "The Lost Son of Havana" and it covers the career of Luis Tiant, the most beloved Red Sox pitcher of the 1970s.  For Sox fans of my age (born in the late 60s), this documentary is particularly meaningful.  A good litmus test for bandwagoners is to ask them what they think of El Tiante. 

For younger Sox fans, what can I say?  Tiant almost won the 1975 World Series all by himself. 

I watched this film tonight.  I believe ESPN will give us several rebroadcasts in the coming months.  Find a time when it's on again and watch it.
