If you really feel there's a compelling reason to chop the legs out from under Garcia, either for more discipline or because a 5 game slice is enough, then play Alu at second every day and go with Thomas, Young, and Blankenhorn as your outfield.
Let's just stop with the Baker in 2023 talk. It's not going to happen because he does not need to be added to the MLB 40 man roster this offseason. IT's sheer idiocy to add him to the roster for the last 2+ weeks of a going nowhere season. Baker's going to get an invite to major league camp next spring, and we can hope / expect he gets a legit shot at 2nd in competition with Garcia and Alu (if Alu isn't slotted in for 3rd base) barring a significant off-season signing.
