BOSTON — Dustin Pedroia didn't do a lot of running on the base paths since his return to the Red Sox post-All-Star break, but he did enough overall to re-aggravate his right hamstring injury.
John Farrell announced on Saturday that the team has placed Pedroia back on the 15-day disabled list.
Pedroia originally injured the hamstring on June 24. He skipped a rehab assignment and joined the team in their first game back from the break in Anaheim. He proceeded to go 0-for-20 at the plate before connecting on an RBI double in the sixth game of the road trip.
After sitting out the last game of the trip, Pedroia was held out of Friday's game, too.
"Yesterday him being down was because of some soreness," Farrell said. "He went through an MRI here this morning and while the strain to the hamstring doesn't show any enlargement, still he's aggravated by the symptoms and feel like he needs some shut-down period to get back over this."
There wasn't a specific play or moment in which Pedroia re-injured the hamstring.
"The play in-game obviously built back up on him to the point of the aggravation," Farrell said. "Can't say that there was a singular event that caused what he was feeling. As he was going at it each and every day, the symptoms continued to persist and after the further imaging and further consultation between the medical staff it was determined the best course of action was to put him on the DL."
Farrell wouldn't say that a rehab assignment would have prevented Pedroia from re-injuring the hamstring, instead saying that he was cleared to play.
Farrell also wouldn't guess as to how long Pedroia would be down for, seeing as three weeks wasn't enough the first time around.
Steven Wright was activated to the 25-man roster in the corresponding move and will start on Saturday.
Farrell hopes to "readjust" the roster in the coming days, most likely adding an infielder.
