Lively (illness) allowed a hit and struck out three without walking a batter over three scoreless innings in his rehab start versus Triple-A Omaha on Thursday.
Lively began the season on the 15-day injured list, but he was solid in his first rehab appearance. The right-hander was in contention for a rotation spot during spring training prior to coming down with a respiratory virus. It's unclear what his role will be with the major-league team once he's activated -- that will likely depend on Carlos Carrasco's performance as the Guardians' fifth starter and the timeline for the return of Gavin Williams (elbow).
