Winker (back) is out of the lineup for Game 1 of Tuesday's doubleheader against the White Sox, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

Winker was removed from Sunday's game with back spasms and wasn't part of the Nationals' lineup for Monday's matchup against the ChiSox, which was postponed. While it's possible Winker could return for the nightcap Tuesday, it's more likely he'll receive the full day off. Nick Senzel will handle DH duties during Game 1.
