Young (elbow) walked and hit a batter but struck out three in a scoreless inning in his first rehab appearance with Double-A Columbus on Tuesday.
Young began a rehab assignment Saturday at the rookie-level Florida Complex League with a scoreless frame and followed that up with another scoreless outing as he moved up to Columbus. The left-hander is coming back from Tommy John surgery and is tracking toward a season debut around the All-Star break.
