Smith (elbow) will throw a simulated game Tuesday, and the Red Sox hope the next step will be a rehab assignment, Stephen Hewitt of the Boston Herald reports.
Smith threw 25 pitches during a simulated game Saturday, facing live hitters for the first time since undergoing Tommy John surgery in May of 2016. The plan calls for a similar pitch count Tuesday. Manager John Farrell indicated that Smith will be used in one-inning stints whenever he's eventually ready to pitch for Boston.
