John Dewan has the Mariners for +30 to +35 runs saved in the outfield, about +0 (ish) in the infield ... but -10 runs at catcher and -10 runs at pitcher. Weird. How are you supposed to deal with glove runs given away at pitcher? Everybody runs drills.

No idea why Mike Zunino should be losing quickness behind the plate, or street cred with the umps, but it's something to watch. +1

To your larger point, that the M's focus seems to flick on and off, that's somewhat my impression too. If true, it's on Scott Servais. Who I like.
