Hill (knee) was activated from the 15-day injured list Monday, Chris Cotillo of The Springfield Republican reports.
The Red Sox have confirmed starters for the next few days, and it was reported earlier in the day that Hill would not start for the big club Wednesday as scheduled, so perhaps he is going to work out of the bullpen as a piggyback option for now. He gave up one run on four hits and zero walks while striking out five in three innings in his rehab outing last week.
