I'd bring him back rather than platoon existing guys there (Marwin, Ehire, Astudillo). Astudillo should not be in the lineup regularly and Marwin's ops is okay for your utility guy but not a regular Ib. If we anticipate signing either a 3b or different 1b, then let him go, otherwise I'd rather have Cron starting opening day than Kiriloff, Rooker, etc. Rookies usually have growing pains. Most aren't like Juan Soto or Luis Arraez.
