Walker and the Mets won't play Friday against the Cubs after the game was postponed due to inclement weather.
Walker has recorded quality starts in each of his last six outings and has posted a 1.85 ERA and 0.90 WHIP in 39 innings across that span. Friday's matchup will be made up as part of a doubleheader Saturday, and Walker will start in the matinee while Max Scherzer takes the mound for the second game of the twin bill, Mike Puma of the New York Post reports.
