Wieters (back) is starting at catcher and batting eighth Monday against the Marlins, Mark Zuckerman of MASN Sports reports.

EDGE Analysis

Wieters is good to go after missing three consecutive games with back tightness and a bruised knee. The 31-year-old, who is slashing .238/.294/.359 through 107 games in his first year with the Nationals, will face Adam Conley in his return to the lineup.
