While never considered a top prospect, Ober made his big league debut last June, giving up three runs in three innings and walking two over three innings. He also exhibited excellent control and a stealthy changeup. His 4.19 ERA reflected his excellent control and changeup. In his last 20 starts, Ober has allowed two earned runs or fewer twice. He has a 29:7 K/BB ratio over 33.2 innings and a 2.89 WHIP.
