Yeah, Super GM, you really need to check your facts. Hampton has been pitching pretty well. He's got many more walks then K's. He may continue to improve, but he's been nowhere near the pitcher Kim was in his first few starts if you look at WHIP, K's and K/BB. Wins are definitely based on luck. Hampton may get more, but I doubt it.
Also, do you know what WHIP means? It means walks and hits per inning pitched. If you have a WHIP near 1, you're not going to be giving up too many runs. If your ERA is around four and your WHIP is 1, then luck has not been on your side. If you have a WHIP near 2 and you have an ERA under three, then luck is definitely on your side. WHIP is definitely the best indicator of how well a pitcher is pitching. Of course stamina is important too, but Kim has shown no signs of running out of gas.
His injury was a freak accident and it didn't affect his arm. He threw six shutout this week, so he seems fine. Granted, it was AAA, but still. I'd take Kim over Hampton, definitely.
