I was looking at Hill from before injury and after, not before and after all stars. I know that Hill's ERA is definitely better! But Berg has a better era against NL East batters.
Hill has 14 fewer innings pitched in 4 fewer starts (average that out and see what the difference is). He also has an almost 3/1 K/BB ratio. Hills has a lower WHIP. Hill has 11 QS to Bergmann's 10 in 4 fewer starts. There really is no competition except that maybe Hill isn't as nice as Bergmann.
