Schwarber has moved quickly through Chicago's ranks since being drafted in the first round last summer. He coasted through three levels in 2014 and then hit .320/.438/.579 with 13 homers and 39 RBIs in 58 games for Double-A Tennessee this year before the Cubs came calling. After a successful six-game stint (.364/.391/.591), the club sent him down for his first taste of Triple-A ball in late June. He will represent the team in the 2015 All-Star Futures Game.
Tuesday marked his second homer in an Iowa uniform and he's now hitting .358 through 15 games.
