Agree that key guys you mention appear to be taking big sticky steps forward this year. Plus, Baez seems to be renewed somewhat (positive WAR!), and Dingler, despite his defensive miscues today, seems like he can put together a league average campaign. It's a shame Parker Meadows is not here to show us what he can do, or Vierling to show us if he can at least maintain what he was last year, but hey, you gotta work with what you got.
I also believe that between Scott Harris's roster construction, and AJ Hinch's effective management of that roster during the game, this team feels very much like more than the sum of its parts.
Tell you what, though: I don't know how much longer we can carry Ryan Kreidler. He's hitting like a pitcher.
