Part of Susan Slusser's story about Marcus Semien hitting the DL notes that Bruce Maxwell, lefty-hitting catcher, will be called up to the A's, with a pitcher heading out to make room. I'm curious whether it's Daniel Coulombe, Frankie Montas, or Door Number 3, but what I'm even more curious about is how game situations and lineup decisions play out with Stephen Vogt, Josh Phegley, and Bruce Maxwell all hanging around.

The big obvious benefit of Maxwell's presence is that Bob Melvin can start Vogt at designated hitter sometimes without fear of losing his DH if he wants to pinch-hit or pinch-run for the starting catcher, or if there's an injury.

One also wonders, or maybe one just hopes, that this move is really about the marginalization of Yonder Alonso. Granted that he's had a solid start to the year, we know what he is now, and what he is is an adequate hitter generally, a bad hitter given his position, and the best first-base glove on the team. If we start seeing more lineups with Ryon Healy at first, Trevor Plouffe at third, and Vogt DHing, I'm not going to count that as a bad thing.

We could run through a whole bunch of possibilities, but Slusser's comments to me on Twitter a few minutes go imply that maybe we're not talking about a reliever being sent down after all. She was cryptic, but maybe it's actually a starter hitting the disabled list? If Graveman's weird total-body tightness or whatever he felt is going to cause him to miss time, then the A's can bridge the gap between now and his next scheduled start, on Wednesday, with a position player.

Look, I don't know. Let's just go to sleep and see what happens tomorrow.
