Martinez is starting at DH and batting sixth in Sunday's Game 2 of the NLDS versus Philadelphia.
Martinez began Game 1 on the bench but came on as a pinch hitter in the eighth inning and delivered an RBI single. Jesse Winker was the starter at DH in that contest, and he'll move to the bench to begin the second game of the series. Sunday will mark Martinez's second start at DH for the Mets in the postseason, while Winker has started in that role three times.
