No - when Hiura comes up he's playing 2B and the corresponding roster moves would either be DFA-ing one of the marginal players currently on the 40 man roster that you could hopefully get through waivers (Freitas, Hart, Wilkerson level guys), or working out some sort of trade to make room. He's not nearly a good enough defender to consider him playing SS (or primary infielder considering how the Brewers utilize defensive shifting). The corresponding MLB 25 man roster move should then be figuring out the best option to both improve your offense and maintain roster flexibility (i.e., don't risk losing someone on the MLB roster for nothing in return by having to send him to the minors). With Shaw still struggling mightily at the plate and with still having minor league options, the current best approach would be to option Shaw to AAA for awhile, move Moose over to 3rd, and insert Hiura as the everyday 2B. Shaw could snap out of his funk and Hiura may slump to make this discussion moot and push his initial callup later into 2019 - but right now this move makes too much sense not to think seriously about it. Ahh good points! Shaw could get going any time. It sucks we only have moose under contract for this season, hes mad a good transition to 2B but hes much better over at 3B. I can't wait to see Keston in the majors.
