Kjerstad (hamstring) is running and participating in baseball activities, per MLB.com.
Kjerstad suffered a right hamstring strain during a March 19 Grapefruit League game, resulting in a stay on the injured list to open the season. The 27-year-old outfielder lacks a concrete timeline for a return to the field, though he'll likely need a minor-league rehab assignment before becoming an option to rejoin the Orioles.
