Marte (back) is not in the lineup for Friday's game against the Padres.
Marte was held out of Wednesday's game after leaving Tuesday's contest with a stiff back, and he will miss another game Friday despite the Diamondbacks coming off a team off day. It's not yet clear how long Marte will be sidelined, but with Arizona's playoff hopes fading, there is little incentive for the club to risk Marte's long-term health.
