Matz (knee) could throw off a mound this weekend, Katie Woo of The Athletic reports.

EDGE Analysis

Per Jeff Jones of the Belleville News-Democrat, Matz played catch off a mound Wednesday and did some running on the field, so throwing pitches off the mound would mark another step forward in his recovery from a torn MCL in his left knee. Matz is still likely a week or more away from beginning a minor-league rehab assignment, so he's not expected to be a rotation option for the Cardinals until September at the soonest.
