Matz allowed two runs on six hits and a walk over six innings Sunday, striking out six during a no-decision in the loss to the Giants.
After bouncing around between the starting rotation and the bullpen, Marx posted his longest outing since June 14. The 28-year-old has allowed four runs in 10 innings since rejoining the rotation after the All-Star break. He'll carry a 4.75 ERA into Saturday's home start against the Pirates.
