The White Sox will do TA the courtesy of giving Montgomery time at other positions in 2nd half 2023 unless 1) they’re not planning on keeping TA after 2023, or 2) they want Montgomery to quietly succeed Anderson in 2024 but not ready to trade Anderson quite yet, or 3) they feel Montgomery will outgrow SS eventually.
Moncada is not one to feel any pressure until his option years and not guaranteed ones come into question.
Even then, maybe he’ll be ready for a trade instead, fresh start like Kelenic probably needs as well.
