BOSTON -- Will Middlebrooks turned in two consecutive vigorous days of workouts and came away no worse for the wear. As a result, he'll begin a rehab assignment in Pawtucket on Monday.
On Saturday, Middlebrooks pushed his strained calf by running sprints at somewhere between 90 and 100 percent intensity. After another good day on Sunday, he's ready to see game action.
"He had a strong work day today," manager John Farrell said. He'll go out on a rehab assignment starting tomorrow. Tentative schedule right now is for him to play tomorrow, Wednesday and Thursday. Then [we'll] reevaluate at that point."
The Red Sox have had a rotating group of third basemen take over for Middlebrooks in his absence. They called up Brock Holt for a day soon after it was determined Middlebrooks would be sent to the disabled list. Then Ryan Roberts was signed to be a righty bat at the position and platoon with switch-hitting utility man Jonathan Herrera.
Roberts was designated for assignment on Friday at which point Holt was called up again. In two games, Holt has three hits (3-for-7) and two RBI, including a run-scoring triple on Saturday in the bottom of the seventh inning that gave the Red Sox a 3-2 lead. He scored on a safety squeeze bunt by Herrera and the Sox eventually won, 4-2.
