Stats for debuting players

Dalton Rushing (who just got called up) is starting for LAD tonight but is listed as LAD ST and is X’d out (as if not in the starting lineup). I assume it is just a standard delay in the stats service recognizing a player promotion (and am not worried about it). But I post it here in case it’s actually related to the Jared Young type confusion between MLB & MiLB. No need to reply if this is just the stat service catching up on promotions and maybe needing until an actual stat occurs to switch over.
