Marte (back) served as a pinch hitter, went 0-for-1, and played the field for the final inning in Wednesday's 2-1 loss to the Mets.
Marte was held out of the starting lineup for the second consecutive day due to lower-back soreness, but Wednesday's activity suggests the issue is a minor one. Arizona manager Torey Lovullo said following the game that the infielder was on track to start Thursday's series finale, per MLB.com.
