With their bullpen in desperate need of a fresh arm after pitching 22⅔ innings over the past five games, the Red Sox called up 24-year-old righthander Rubby De La Rosa from Triple A Pawtucket.
De La Rosa was scheduled to start in for the PawSox on Saturday. To make room, the Sox optioned Pedro Beato to Pawtucket
