Anthony Castrovince, a MLB.com columnist, has spent nearly his entire work life writing (and talking) about baseball. In recent years, he’s turned analytics into a talking point. His new book, “A Fan’s Guide to Baseball Analytics,” while thoughtful and witty, takes a serious look at this side of the game. Castrovince, a proud Ohio U. alum and Springsteen fan, wasn’t always an analytics guy. He will talk about his transformation and his book when he joins “Talking Baseball!”
