High-A Dayton placed Arroyo on its 7-day injured list Wednesday with a left hip strain.
Arroyo suffered the injury Saturday and will now be out through at least the end of the week. Cincinnati acquired the infielder in the 2021 deal that sent Luis Castillo to Seattle, and Arroyo has since established himself as one of the top prospects in the Reds organization as a plus defender with some offensive upside.
