Swisher (knee) is expected to begin a rehab assignment at Triple-A Columbus this week, Paul Hoynes of the Cleveland Plain Dealer reports. Swisher has been playing in extended spring training games and, if all goes well, could return to the big league team by the start of May. General Manager Chris Antonetti indicated that he'd like to see Swisher complete back-to-back nine-inning games in the field before reinstating him, so the 34-year-old's progress in the rehab assignment should dictate the next step.
