That I don't doubt, the question is did the sox improve offensively by adding posednik and subtracting lee? and specifically, does posednik make the hitters after him better by being on base (something he is not extraordinarily good at anyway)? No, I don't think Posednik is the reason why the Sox have improved, their offense is down about .7 runs per game or about 113 runs over 162 games. They're worse offensively no deviation ratio can overcome that lack of runs. The only way you can overcome that drop in offense is by giving up fewer runs. The White Sox have allowed 3.94 runs per game this year, last year they allowed 5.12 runs per game., a difference of 191 runs over 162 games. They've improved almost a .5 runs per game as far as run differential. They probably are hitting better in close and late situations, but the reason they doing so well in 1 run ball games is b/c Cotts, Politte, and Hermanson in the 7th, 8th, and 9th moreso any improvement in situational hitting.
