Stewart (groin) is expected to appear in back-to-back nine-inning games later this week, Bill Brink of the Pittsburgh Post-Gazette reports.
The backstop was scratched due to groin soreness last week, but it seems like he's nearing game action after slowly ramping up his activity over the past few days. As long as his rehab process goes without a hitch, Stewart should be able to resume his position as the backup catcher for Francisco Cervelli soon.
