Mets manager Carlos Mendoza said Wednesday that Soto (back) is still being evaluated and it's possible the outfielder could need a stint on the injured list, Jorge Castillo of ESPN.com reports.
Soto was forced to depart Tuesday's game versus the Cubs with tightness in the left side of his back, and he is not in the lineup for the first game of Wednesday's doubleheader. A decision on a possible trip to the IL for Soto is expected to be made later Wednesday.
