Rafaela is not in the lineup for the first game of Friday's doubleheader against the Cubs.
Rafaela didn't have to miss any starts because of a right hamstring cramp that he suffered Wednesday versus the Guardians. Presumably, he's simply resting for the first game Friday and will be back in action for the nightcap. Jarren Duran will play center field for the Red Sox during the afternoon tilt.
