If you had a 5+ year MLB vet who had never touched a .250 BA, then I think it’s fair to say he’s unlikely to achieve such a number. If you’re talking about a guy with barely a full season of MLB PAs under his belt, then I don’t think it’s fair to box them into whatever their production is to date. Brice Turang was a .220 hitter after his first season and now look where he is. Development takes time and Ortiz certainly may never get there, but it’s too soon to tell
I would also say Ortiz is a career shortstop more than a career utilityman. 80% of his innings in the minors came at SS. It is an adjustment to play it at an MLB level and that might be playing a role in his production at the plate, but it’s not like he’s learning a new position
