Matz has been out since mid-August due to a shoulder impingement.

He last pitched on Aug. 14, when he allowed one hit in 7.1 innings while walking two and striking out eight against the Padres.
Matz has a 3.40 ERA and 1.21 WHIP with 129 strikeouts in 132.1 innings (22 starts) this season.
There have been so many stops and starts as Matz recovers from his shoulder issue, but perhaps this time will be the charm.
Aside from the shoulder impingement, Matz is pitching with a bone spur in his elbow that will require surgery after the season.
However, doctors have told Matz he can’t do any further damage by pitching with the bone spur — and it appeared he had finally learned to deal with the issue in the handful of starts before the shoulder issue popped up.
