The Cardinals remain undecided on whether to have pitcher Michael Wacha make another rehab appearance during the Triple-A playoffs or rejoin the Cardinals, MLB.com reports.

Wacha threw 34 pitches in his rehab start with Double-A Springfield Monday, giving up one hit and one walk during two scoreless innings. "Very good," manager Mike Matheny said of Wacha. "He had good velocity, was efficient, got quick outs and located everything well."

If Wacha were to pitch with the Cardinals later in the week, he would be on a limited pitch count as he continues to rebuild arm strength. The pitcher has been sidelined since June 17 with a shoulder issue.
