Triple-A Memphis reinstated Newsome (elbow) from its 60-day injured list Monday.
Newsome, who has been on the shelf all season while recovering from the Tommy John surgery he required last summer, is ready to rejoin the Cardinals' top affiliate after he recently wrapped up a six-appearance rehab assignment in the lower rungs of the minors. Between stops in the rookie-level Florida Complex League and with Single-A Palm Beach, Newsome struck out seven and allowed two runs on eight hits and one walk over 6.1 innings.
