Matz (elbow) threw about 20 pitches off the rubber in a side session Tuesday, Matt Ehalt of The Bergen Record reports.

EDGE Analysis

It's a small step forward in the recovery process for Matz, who had previously been limited to throwing off the slope of the mound in his last workout Sunday. Matz should gradually increase his pitch count in subsequent bullpen sessions before advancing to facing hitters. The Mets don't have an official timetable for his return from the 10-day disabled list, but it's still looking as though he's multiple weeks away.
