Kopech will serve as the Dodgers' opening pitcher for Game 6 of the NLCS against the Mets on Sunday, Noah Camras of DodgersNation.com reports.
Ryan Brasier served as the opener the last time the Dodgers went with a bullpen day in Game 2, but after suffering a 7-3 loss in that contest, Los Angeles will go a different route Sunday. Kopech's lone appearance in the NLCS came in Game 3 on Wednesday, when he scooped up a win while striking out one batter over one scoreless inning. He's appeared in five postseason games this season, allowing one hit and two walks while striking out six batters across 4.1 scoreless innings.
