Muncy will start at first base and bat fifth in Game 6 of the NLCS against the Mets on Sunday, Noah Camras of DodgersNation.com reports.
Enrique Hernandez will start at third base Sunday while Muncy shifts to first base due to Freddie Freeman (ankle) being absent from the starting lineup. Muncy has gone 5-for-13 with nine walks, two home runs and four RBI over the first five games of the NLCS.
