Only one of those players has more PS at bats than Soriano, and that's Dimaggio. I wouldn't consider anything under 100 AB in the post season an indicator. The rest: 64 AB, .314 OBP for Cobb 129 AB, .320 OBP for Mcgwire 47 AB, .317 OBP for Helton 140 AB, .304 OBP for Schmidt 106 AB .354 OBP for Bagwell 167 AB .297 OBP for Biggio 120 AB .301 OBP Piazza 68 AB, .315 OBP for Cabrera 174 AB, .263 OBP Soriano Why is 100 ABs the magical cutoff point? At 150 ABs numbers still can be altered drastically by a small number of at bats. Soriano's current numbers could shift 20-30 points in the span of 10-15 ABs (less than a postseason's worth). Why do 100 at bats become useful in evaluation and why wouldn't you want an even larger sample size (such as the entire regular season)? Also, Biggio, Piazza, Schmidt and McGwire all have more than 100 ABs in the postseason and have horrific OBPs. Would you drop them in the order?
