I was reading Bryan Hoch's MLBlog and this is what he wrote:
"Joba Chamberlain was swinging a long athletic sock around his shoulder with three baseballs in it. Though it'd probably make a handy way to ward off a mugger, Joba is collecting autographs to help decorate his son's bedroom. Chamberlain said he's already scored signatures from most of the star players on the Yankees, as well as a few jerseys."
I hadn't realized Joba is a father; does anyone know any more information??
