Joba has the stuff and the location to smoke any team. It is the pitchability and the pitch calling that needs to be consistent for him to have a successful season from top to bottom. Early on, when he was making the change to the rotation, he hardly threw the curve. It was pretty easy to figure him out in starts 1 and 2 since the slider was breaking out of the zone and the heater was the only pitch he could locate. The curveball has started to get integrated in and it is nice. He locates it better and more consistently than he does the slider. It gives him more of a change of speed than the slider does and it has a deep break. If he is locating 2 of his three pitches, he is dominant. If he locates all 3, he wont be stopped. In terms of his changeup, I have only seen him use it a couple times a game. It was the pitch that got hammered in most of his MiLB reviews and for good reason. It doesnt have any break to it. It will likely be the focus of his offseason, because right now it isnt even worth mixing in.
