He will look good for 2-3 starts and then at random throw a gem like this last game. But its pretty certain after a few games he's perma-fade until he gets cut again.
One thing to note, don't pay attention to AAA or AA stats for experienced major leaguers. Most guys go out there throwing at about 80% of their capacity and often just work on one or two pitches. If another team bangs him around, he doesn't care, he's still not bringing in the 3rd or 4th pitch to keep the other team off balance. Kids trying to get to the majors will bring 100% and use every pitch they got. If you are a vet, you figure you still will get to the show so its just practice.
