It's fair to argue that the ALC teams have received a boost from being able to wail on the White Sox all year. That said....good teams should wail on bad teams. When they don't, it has seriously negative impacts on them and they are rightly criticized. Look no further than the 22-23 Timberwolves who were a play-in team rather than a #3 seed by virtue of a god awful record against terrible teams. Even a .500 record against the dregs would've earned them a huge bump in the standings.
The Twins have had long stretches of really good baseball this year. They've had long stretches of really bad baseball this year. Perhaps they're just mediocre. Given the way the roster was gutted of depth, that would seem to make sense. They banked on big performances from young guys and got mixed results. (Julien, Wallner, Lee, SWR, Lewis, Larnach, etc) They banked on come-back performances and got mostly bad results. (Margot, Paddack, Vasquez, Kepler) They banked on star/established players carrying them and again got mixed results. (Correa, Buck, Lopez, Duran, Jax, Santana, Theilbar)
All and all, the fact they'll finish with a (just barely) winning record is about what was reasonable. It might even be a bit surprising given the injuries.
