Vosler led Double-A Tennessee with 21 home runs and 81 RBI this season.
Vosler played 129 games for the Smokies and slashed .241/.343/.429. With the trades of Jeimer Candelario and Eloy Jimenez this season, Vosler has moved into the discussion as one of the Cubs' top-10 hitting prospects. The 23-year-old is blocked by Kris Bryant at third, so a position change may be necessary to make it to the big leagues, at least without switching organizations.
