Marte is out of the lineup for Wednesday's game against the Mariners.
Marte has been stuck in prolonged slump at the plate, as he's slashing just .152/.200/.318 with a 25.7 percent strikeout rate over a stretch of 21 games dating back to June 22. He'll hit the bench for the third time in four contests and looks to have faded into a part-time role while the Reds have reopened more playing time for Nathaniel Lowe.
