Cubs general manager Jed Hoyer indicated Tuesday that prospect third baseman Josh Vitters is likely to be called up from Triple-A Iowa in the near future. Vitters, who turns 23 later this month, is hitting .296/.349/.496 with 15 home runs, 63 RBI and an .846 OPS in 106 games this season at the Triple-A level. There are serious questions about his plate discipline, but he should get a look as the Cubs evaluate their internal options for 2013. He might be worth a stash in NL-only formats.
