Red Sox pitcher Zack Kelly got one step closer to a major league return, making a rehab start in High-A Greenville on Friday night.
The right-handed reliever hasn’t pitched since his injury against the Tampa Bay Rays on April 12. He left the mound in visible pain, drawing the attention of Alex Cora and Boston’s medical staff. Shortly after, he underwent surgery on his right elbow.
On Friday, Kelly pitched one inning in the first leg of his rehab schedule. He retired the side in four batters without a hit, earning a pair of strikeouts, and walking one batter.
