Against a good RH with a good breaking ball, WMP is still quite helpless. He has been feasting on bums right now. He will not feast on good pitchers that don't live in the middle of the plate. In a big spot against the other teams top reliever, I'd still be more confident with Nixon than WMP. WMP will be an offensive force eventually, and he is on his way, but Nixon is still a tougher out.
