You were always all-in on Marsh. So was I. But not everyone was (nor have they ever been, even when he's been perfectly good).
Regardless, it appears Thomson and DD have handled it all masterfully. They didn't DFA Kepler or immediately bench Kepler or Nick, the two guys who both squawked about their playing time, on August 1. You might think that was coddling; I think it was good psychology, and letting everyone earn or not earn their role. Bader and Kepler answered the bell (and Marsh already had long ago); we'll see if Nick is able to (but didn't so far). He's probably going to play today or tomorrow against a RHP before facing the Mets lefties. LHP is still the key to shutting down the Phillies in October; we'll need him at some point.
And people are just weird about platoons for some reason. The Comcast talking heads were, by way of praising the current arrangement, complaining about how much they don't like not having "full-time" players. Of course you'd rather have them than not but managers who insist on playing guys like Casty (or, for much of his career, Bohm) as if they don't have a platoon split is an even bigger problem IMO.
It's true Marsh hasn't gotten enough reps to get better over his entire Phillies career, but platooning both him and Stott has been great for this team this year. And now the combination of Kepler being a decent bat and his defense plus Nick's struggles makes putting Nick in the weak side of one a no-brainer too. We are lucky to have three really good RHB platoon hitters now, even if Nick still needs to show something. Many teams don't platoon simply because the bench guys aren't good enough, even from their strong side. That was Kepler this year for a while.
9th inning of the NLCS, man on second in a 2-1 game, Tanner Scott on the mound for the Dodgers, Kepler coming up. Do you put in Wilson or Casty? Sosa?
