Martinez (elbow) will begin a rehab stint at Triple-A Toledo on Tuesday, starting as a designated hitter, Katie Strang of ESPN reports.
The Tigers seemingly aren't in any rush to get Martinez back in Detroit, so it's possible that the outfielder will take a longer-than-usual rehab assignment at Triple-A. That being said, his ability to play in the outfield while with Toledo will be the signal that he's likely a few days away from rejoining the Tigers.
