I would imagine that now that Acuna is in Syracuse, that Ronny Mauricio would replace Lindor at shortstop (in an emergency) since he spent the majority of his MiLB career (395 games) at shortstop. Brett Baty has never played shortstop during his professional career, so I don't expect him to start now with the Mets. Jeff McNeil has played 1 inning at shortstop during his MLB career. I love McNeil's versatility, but I don't wish to see him manning shortstop unless it is a dire emergency. If Lindor had to miss significant time, heaven forbid, then I would expect a quick call for Acuna to take his spot.
