Where Does Sabermetrics Fit In?

Sabermetrics. Analytics. Billy Beane. Money Ball. ERA+. FIP. WAR. WHIP. A lot of terms. A lot of material to digest if you are a big league manager. Where does analytics fit in today during the modern baseball era? Some managers & teams discard sabermetrics completely & stick to the old school, eye-test type of decision-making. I think those teams, however, are very very few in this day & age. The Houston Astros, for example, have a complete department of analytics. These new stats have been credited for the recent success of the Pittsburgh Pirates. For example, signing Andrew McCutchen to a long-term deal seemed dumb at the time, although prudent as measured by analytics, & now he is way outperforming his contract. If I were a manager, I would want certain types of data that I feel would help me in general or on that particular day -- who hits certain pitchers best, which guys should we shift on, etc. At the same time a manager knows which of his players is hot, who feels good that night & who is available. To me there is room for both old school & new school, eye-test & managerial experience or intuition & sabermetrics to all co-exist piecefully together. Don't rely on just one or the other. Use all the tools available.
