Re: Buster Posey injured
If he is injured, wouldn't Ramon Hernandez make a nice fill-in for them? Moving him would allow us to bring up Mes, with Hannigan getting the bulk of playing time while Mes acquits himself with the major leagues.
Sabermetrics can be boiled down to this simple truism: A batter's goal is to extend the inning. Extend enough innings and you're going to score runs. Extend more innings than your opponent and you're going to score more runs than him.
