MESA, Ariz. -- A day after getting hit on the right arm with a pitch, Chicago Cubs shortstop Starlin Castro was cleared to participate in all activities.

"It's good, a little sore," Castro said Tuesday morning, rolling over his right arm to expose the area where he was hit.

Castro was participating in live batting practice Monday afternoon when he was hit on the inside of his right forearm by a Kerry Wood fastball. After a brief rest, Castro returned to batting practice.

Pitcher Paul Maholm, who has been in and out of action since coming down with the flu on Saturday, is expected to participate in a full workout Tuesday.
