Rosario will start at designated hitter and bat ninth in Wednesday's contest versus the Astros.
It's the fifth straight start overall and fourth straight start against a righty for Rosario, who is traditionally a much better hitter versus left-handed pitching. He's slashing .250/.300/.357 with one home run and two stolen bases in 10 games since joining Cincinnati. Rosario could continue to play pretty regularly while Jeimer Candelario (toe) is out.
