Kimbrel (knee) will throw one inning his first rehabilitation outing Saturday for Triple-A Pawtucket, and then the team will assess his readiness on Sunday to determine if he should be activated from the disabled list, Peter Abraham of the Boston Globe reports.
It was just 19 days ago that Kimbrel had surgery on his left knee, and now it's looking like he can make it back to the team early next week in time for the series against the Mariners that begins Monday. With his return, the Red Sox will need to make a roster move and could look to trade one of their relievers before Monday's trade deadline.
