Matz (side) is schedule to throw 60 pitches in a rehab start with Double-A Birmingham on Wednesday, so it's possible he'll require an extra one, ESPN New York reports.

Matz should rejoin the rotation when healthy, but it's a bit unclear at this point when that will be. When he does return, the Mets may decide to employ a six-man rotation throughout the month of September to save their young arms some stress.
