Donaldson (calf) participated in live batting practice Monday, Do-Hyoung Park of MLB.com reports.
Donaldson missed the final two games of the regular season with a right calf cramp, but he took batting practice with the Twins on Monday, just one day before Game 1 of the AL Wild Card Series. The team hasn't announced whether he'll be available to begin the series, but his participation in batting practice is an encouraging step.
