EDGE Analysis

The original hope was that deGrom would only miss his next start but that now appears not to be the case. Rafael Montero is starting for deGrom on Tuesday and could remain in the rotation. That might change if Steven Matz (shoulder) is able to return, allowing Seth Lugo and Robert Gselllman to fill the two open rotation spots.
