OBP = On base percentage
SH = Sacrifice hits
SF = Sacrifice flies
3B = Triples
GDP = Grounded into double play
SO = Strikeouts
SBE = Second batter evaluation
SBE = OBP( SH + SF + 2B + 3B) X100
GDP + SO
Derek Jeter's SBE = 0.355(37) X 100
91 = 14.4
A 14.4 SBE is above average, Derek Jeter is a pretty good number 2 hitter.
Dustin Pedroia's SBE = 0.387(49) X100
97
= 19.5
A 19.5 SBE is great. Pedroia would make an excellent number 2 hitter
For an additional fact: most lead off hitters are left handed. Having a number 2 hitter who is right handed or a switch hitter would negate the left on left and right on right match ups that the opposing managers love to use so much. With a right handed pitcher coming in to face the number 2 hitter, that right handed pitcher may stay in the game to face the left handed, slugging number 3 hitter.
