"There's been more emphasis on just targeting the strength phase and building up his physical base," said manager John Farrell. "I know we talked about Detroit being the target date for some baseball activity. With all the information that's been gathered on [Pedroia] and everyone weighing in on him, there was a high level of comfort to send him back to Boston and focus solely on gaining some strength in that hamstring."
At some point during September, the Red Sox expect Pedroia to be back in the lineup.
"I think it would be beneficial to everyone, particularly for [Pedroia]," said Farrell. "Keeping in mind we don't want to jeopardize anything, if he can go into the offseason knowing he got back on the field and feels like there's no restrictions, that would be helpful to everyone."
Pedroia initially suffered the injury while running the bases on June 24. He returned after the All-Star break for six games, only to be forced back on the disabled list.
