CLEVELAND — Kyle Schwarber has been added to the Chicago Cubs’ World Series roster and could start Tuesday night’s opener against the Cleveland Indians at designated hitter. The 23-year-old, sidelined after tearing two knee ligaments on April 8, was included Tuesday on the Cubs’ 25-man roster. Left-handed pitcher Rob Zastryzny was dropped. Schwarber was expected to miss the rest of 2016 following knee surgery but was cleared medically to resume playing on Oct.
