Stewart faced live hitters early this past week but is still experiencing discomfort in his left foot, MLB.com reports.
Stewart landed on the 15-day injured list May 9 due to a bone spur in his left foot. He was originally given a three-week timeline to return, but that period has since come to pass. It's not clear how much longer the continued foot discomfort will keep Stewart on the shelf. At this time, surgery hasn't been viewed as an option for Stewart, but that could change if the discomfort persists.
