Polanco is out of the lineup for Sunday's game against the Pirates.
Polanco served as the designated hitter for the first two games of the series, but he'll cede those duties to Brett Baty in the finale. Since being activated from the 60-day injured list July 7, Polanco has yet to start more than two consecutive games and has put together a wretched .097/.138/.177 slash line with one home run, three RBI and four runs.
