Pirates' Chris Stewart: Knee responding well in rehab starts

Stewart's knee has been responding well so far in his rehab assignment and he will continue to play nine innings every other day with Double-A Altoona, the Pittsburgh Post-Gazette's Bill Brink reports.

Analysis:

He began the rehab assignment on Aug. 12, and likely won't rejoin the Pirates until rosters expand in September, at which point he might get one start per week for the big league club. Stewart is 2-for-14 with five walks in six games with Altoona.
