Pirates catcher Chris Stewart went 0 for 2 with a walk in the first game of his rehab assignment with Double-A Altoona Thursday.
Stewart initially injured his hamstring on March 9, and the issue caused him to open the season on the disabled list. He was also caught trying to steal second base in the third inning Thursday, and ended up catching eight innings before being removed for a pinch hitter in the ninth. Provided he doesn't encounter any setbacks, he could be back with the team soon.
