I'm keen on getting Mervis up with the team somehow, he could fit as a DH vs RHP. I still like his bat. With Busch and Cooper plus Wisdom I just don't know how it happens without an injury to Busch at this point. They aren't going to carry a whole bunch of 1B.
They need Canario up as an OF though, they can't roll with 3 OF, and he compliments Tauchman with the RHB. Mastro sucks and looks like Cooper may only play OF in a pinch vs LHP, he doesn't seem to move very well.
I would like to see Mastrobuoni swapped with someone, possibly even Mervis. Between Swanson, Nico, Madrigal, and Morel I think we have enough players who can play middle INF at least in a pinch, Mastro doesn't fill a role if he can't hit or even field particularly well and he's just rotting on the bench as an emergency infielder at this point.
