That's pretty much how I'd do it too. I started going into the roster decisions when Mo Egger was going on and on in the pregame show last night about not needing Hamilton on the postseason roster. Someone called in to ask who Mo is taking instead of Hamilton, and he danced around the question without answering it.
I went back and looked at the 1990 team. Billy Bates had a total of 1 plate appearance in the NLCS and WS. He had a career total of 58 plate appearances over a couple seasons. Mo kept going on and on about Hamilton having no experience at the plate against MLB pitchers...but Billy Bates didn't either.
