LOS ANGELES — Shortstop Corey Seager was left off the Los Angeles Dodgers' roster for the NL Championship Series against the Chicago Cubs on Saturday.
The Dodgers announced Seager's surprise omission due to an apparent back injury several hours before Game 1 at Dodger Stadium.
Los Angeles also dropped reliever Pedro Baez from its roster. Infielder Charlie Culberson and outfielder Joc Pederson were added.
Chicago made only one change from the last playoff round, adding right-handed reliever Hector Rondon and removing left-handed reliever Justin Wilson.
Seager complained of back soreness during the Dodgers' NL Division Series clincher in Arizona on Monday, and 2016 NL Rookie of the Year didn't participate in team workouts this week.
