Recommendation: In spite of the setback, Harrison's timetable isn't expected to change all that much. The Rangers remain convinced Harrison will be able to pitch this season, but it could be well after the All-Star break. He's probably droppable at this point in most mixed leagues and shallow AL-only leagues with limited bench slots.
