i hate to beat a dead horse, but i really don't know why people persist with this fallacious nonsense. find me any statistician/sabermetrician who is willing to reconcile just simply throwing half of your sample in the trash. and if we're just not concerned with sample sizes, well then hell he's showing to have a 528 ops true talent level at this point in his career. Are you talking about dismissing the fact that Petco has drastically suppressed offensive numbers across the board (AVG, SLG, Runs, OPS, etc.) for both home and visiting teams for its entire existence? That we can ignore the fact that nearly every San Diego Padres hitter who has played in the park has had fairly extreme home/road splits favoring the road, and vice versa for their pitchers? If so, that's fallacious nonsense. It would make things simpler if we could look at numbers independent of their context, but that would be a very myopic form of analysis. No one is saying to throw his home numbers completely out, but you can very reasonably project a marked improvement in overall numbers for any San Diego Padres player who moves to a more hitter friendly park. And I could find you a truckload of sabremetrecians who would agree with that. It's like Coors reversed. You can go back and look at all the numbers, there isn't much room for selective interpretation. If we are having this discussion in March, 100% of ML general managers swap Theriot in favor of Greene without hesitation, I promise you. His splits indicated he would benefit greatly from a change of scenery, and his numbers were trending upward right at the age you would project them to. Having said all that, clearly whatever is ailing Khalil Greene this year goes way beyond park factor. No one could have reasonably predicted it, but it would definitely make me think more than twice at this point.
