You are right for the most part, they aren't terribly relevant. Although if Arcia was 6/14 (like Colabello is) and Colabello was 2/18, I would bet Gardy would have Arcia in the starting lineup. Colabello is hot, so he wants him in the lineup. Kubel has started once so far so my guess is he wanted to get him into the lineup. You seem to be getting pretty worked up when we are only five games in. Arcia has more than twice as many AB as Kubel and would be 3X if Kubel hadn't played the long game in Chicago. By the end of the year, Arcia should have 500-550 AB and Kubel around 350 since he will most likely be the primary DH against RHP.
