Re: Kyle Lohse
Unless you're Johan Santana, every pitcher is a mix of good and bad nights. You can't discount the streak of 16 scoreless innings unless you similarly discount that 4 IP, 6 ER outing he surely has coming up at some point. However, you can start to judge pitchers by their aggregate performances. At this point, Lohse looks like Milton with a higher top end, thus making his overall numbers a bit more palatable.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
