There's no stat for this, but someone will probably try to find one anyway: Devers has no superstar protection batting directly after him in the line-up. I've been worried about this since last winter...
He's drawing more walks -- and expanding the zone -- because teams have no reason to throw him anything he can reach in a big spot. If you watch enough games, you recognize the plan: "pitch around him -- if he swings at crap, we get him out; if he doesn't, we'll get the next guy... just don't let Devers beat us." The Seattle manager who did, lost the game, and just lost his job (maybe it was a coincidence).
Refsnyder, Wong and O'Neill have all had productive seasons, and heroic moments, but none of them are as feared with a bat like Raffy, the Red Sox' record-setting 28-year old. Maybe Casas, once he shows he's fully healed (if possible this season), can bat behind Devers.
Or maybe someone like Anthony or Campbell can soon be that guy, so Raffy can finally have a Manny-Papi or Judge-Soto season. Put it this way: does any fan think Devers has truly peaked, and is incapable of an even better career year someday?
