Stephenson is not in the lineup Tuesday against the Rockies.
Curt Casali is starting at catcher and batting ninth versus the visiting Rockies and right-hander Noah Davis. Joey Votto will serve as the Reds' designated hitter and bat sixth. Stephenson has gone 0-for-8 with three strikeouts over his last two games and holds a disappointing .681 OPS on the year.
