Other things just to keep in mind, the roster does expand to 28 in September so there is a little more flexibility possible, though not wacky 40 as it was prior to 2021.
Also the Twins off days are kind of bunched up. After this 13 games in a row stretch, they are off 7/27 & 7/31. Then another 13 game in a row stretch with 3 days off in rapid fire, 8/14, 8/17 & 8/21. Just saying switching up the order could be enough specifically with Ober in terms of load management.
I don't think they have any make-up games on the horizon where they "need" a spot starter, but still they might go the 6man route.
