Smith (elbow) noted that he experienced some tightness after his bullpen session a week ago, but still plans on throwing again next week, Tim Britton of the Providence Journal reports.
It doesn't appear that the soreness is anything out of the ordinary for Smith, who is working his arm back to full strength following Tommy John surgery in May of 2016. He's hopeful to return to game action at some point in June, but he still has many hurdles to overcome in his recovery before the Red Sox will provide a clearer timetable. Look for Smith to open the season on the 60-day DL in order to give the Red Sox a little more roster flexibility.
