Chapman (finger) took groundballs, threw to bases and hit in the batting cage Monday, Ethan Diamandas of SI.com reports.
Chapman has been performing baseball activities for a few days, and he will repeat Monday's workout Tuesday. The report add that "it's about pain tolerance at this point" for Chapman, but he won't return from the 10-day injured list "until he can comfortably hit" against a high-velocity pitching machine.
