Defensive Spectrum




The defensive spectrum looks like this:
# Designated Hitter
# First Baseman
# Left Fielder
# Right Fielder
# Third Baseman
# Center Fielder
# Second Baseman
# Shortstop
# Catcher

Like many original sabermetric concepts, the idea of a defensive spectrum was first introduced by Bill James in his ''Baseball Abstract'' series of books during the 1980s. The basic premise of the spectrum is that positions at the bottom end are more difficult than the positions at the top end of the spectrum. Therefore, the positions at the top are easier to fill, since the physical demands are less as you move left along the spectrum. A corollary to this is the fact that, since defensive skill is at less of a premium at the top end, players at those positions must provide more offense than those at the bottom end. Another corollary is that players can generally move from bottom to top along the specturm successfully during their careers.
