Cardinals manager Oliver Marmol said Monday that Matz (back) will have his pitch count scaled back to 65 in Tuesday's rehab start with Triple-A Memphis, Lynn Worthy of the St. Louis Post-Dispatch reports.

That's after he threw 85 pitches in his last outing with Memphis. The idea behind reducing Matz's workload is to keep him flexible for a variety of roles when he rejoins the Cardinals, as it sounds like he could be used as a starter or a reliever or both. Tuesday's rehab appearance is expected to be the final one before Matz is activated from the 60-day injured list. He's been out since late April due to a herniated disc in his back.
