Boston Red Sox starters Garrett Whitlock and Tanner Houck each threw bullpen sessions on Tuesday, The Athletic’s Chad Jennings reports.
Both pitchers have been on the 15-day injury list for over a month. Whitlock has been sidelined since July 3 with a bone bruise in his elbow, and an unlucky line drive to Houck’s face has kept him out since June 16.
The Red Sox have used both Whitlock and Houck exclusively as starters this season.
