It's not possible to get that big and maintain the size through a MLB schedule. It'd be one thing if a guy like Sosa was a bodybuilder for a living, but he's got to travel every few days, play a three hour game (plus practices, meetings, breaking down film, etc). For a guy like Sosa you have to add in all the PR stuff, appearances with sick kids, filming Pepsi commercials, etc. You can't lift in a gym 2 hours a day and still do all the above stuff without help. http://www.wisecamel.com/images/Sosa%20B%20and%20A%203.jpg
