The Marlins added Hensley to the 26-man roster Tuesday, Christina De Nicola of MLB.com reports.
The Marlins claimed Hensley from the Astros on Monday, and with Miami making a slew of trades at the deadline, Hensley will immediately join the active roster. It's unclear if the utility man will stick around long-term or just serve as a fill-in option until Kyle Stowers and Connor Norby arrive from Baltimore.
