Ridings was placed on the 60-day injured list with a right shoulder impingement Tuesday.

EDGE Analysis

Ridings tossed five major-league innings last season after an impressive showing in the upper minors, but he won't get to add to that total until at least early June. It's unclear exactly when he's expected to return, and he may not have a guaranteed spot on the 40-man roster to return to given his relative inexperience.
