After the Red Sox traded Chris Sale to get Grissom this offseason, the 23-year-old has only played in 23 games. He began the year on the IL with a hamstring injury and then was sidelined a month later when they resurfaced. According to McCaffrey, “The Red Sox have tried to balance out the strength in each hamstring to ensure he can stay on the field.” With David Hamilton playing well, the Red Sox likely won’t rush Grissom back, but his eventual return could complicate playing time in the middle infield.
