The 23-year-old Schwarber returns to the team a little more than six months after having surgery to repair two torn ligaments in his left knee. Doctors cleared him last Monday to hit and run, but he won't play the field.
The AL champion Cleveland Indians will host Game 1 of the World Series on Tuesday night. Schwarber is likely to be the Cubs' designated hitter in some or all games played in Cleveland, and he'll be used as a pinch hitter when the series shifts to Wrigley Field.
Schwarber takes the roster spot of lefty reliever Rob Zastryzny who was needed in the NLCS due to a heavy left-handed hitting Los Angeles Dodgers lineup. The Cubs will employ 11 pitchers and 14 position players for the World Series, the same amount they used in the NLDS. There were no other changes to their roster from the previous round.
Schwarber is the franchise's postseason home run leader after hitting five in 2015. He made his first career start against the Indians last June, going 4 for 5 at Progressive Field. He's also an Ohio native.
