Workman (elbow) will start his rehab assignment with Rookie Gulf Coast League Red Sox on Tuesday, Jason Mastrodonato of the Boston Globe reports.

EDGE Analysis

Workman continues to recover from Tommy John surgery that he underwent a year ago, and will make his first pitching appearance since 2014 in the near future with the Rookie-level team. The 27-year-old could be back with the big league club around the beginning of September, but the Red Sox will likely be careful with Workman and could hold him out the rest of the season if he isn't coming along after spending time rehabbing and recovery from his injury.
