That's not an actual mid-season solution.
Good topic for an individual thread if someone wants to start one. Practically speaking I think he'll be rehabbing in AAA for a bit, so you can punt on that a bit longer unless he's just tearing the cover off the ball there. Let's say that is the case though - I don't think there's that much room for Yelich at DH beyond what he's doing today, since Contreras seems intent on playing every day and he and Sanchez will take the bulk of those. Or I guess that's a possible choice - you sit Sanchez more, but then your OF better be outhitting what Sanchez would contribute.
Otherwise, assuming Chourio is not sent down, then I guess you just spread the ABs around, either evenly or based on who's hot?
