Chapman (shoulder) threw a side session Saturday and is on track for a June 15 return date, Bryan Hoch of MLB.com reports.
This is yet another encouraging development in Chapman's rehab as he threw 15 pitches on the side Saturday. The Yankees will likely continue to have him gradually ramp up his workload in the coming weeks with the intent of getting him back in Pinstripes by the middle of the month. Given the length of Chapman's absence, the Yankees could send him on a brief rehab stint before activating their hard-throwing closer.
