Dodgers All-Star shortstop Corey Seager has been left off the team's NLCS roster with a back injury. Dodgers manager Dave Roberts said on Friday that Seager was questionable for Game 1 with what he described as a muscular injury in Seager's back, but he did not suggest that Seager might not be able to play in the series altogether. It's a major blow to the Dodgers, as Seager, 23, hit .295/.375/.479 with 22 home runs and 33 doubles this season and plays strong defense.
