Garrett Whitlock (knee) navigated a scoreless inning in his first minor league rehab appearance at Triple-A Worcester on Saturday.

It wasn’t the smoothest of innings, as Whitlock gave up a hit and a couple of walks and threw just 10 of his 21 pitches for strikes, but he managed to escape without any damage being done. His fastball topped out at 97-mph in the outing. It’s unclear if the Red Sox will want to see him once more in a minor league setting or if he’ll be cleared to return following Saturday’s appearance.
