Marte is taking groundballs and hitting during practice but is not yet up to full speed after missing time due to a hamstring injury, Jose M. Romero of the Arizona Republic reports.
Marte served as the designated hitter for a fifth consecutive game Sunday. The Diamondbacks are being careful with their starting second baseman, who's had a history over hamstring injuries. The team is off Monday, so the next chance for Marte to take the field is Tuesday against the Padres.
