True, but that doesn't mean a second small sample is going to follow what the first small sample did. The whole point of small samples is that they are going to fluctuate wildly, which is why partial year bench numbers are often misleading. I'm not sure 131 PA of Aaron Miles when he was hurt tells you much about what he's going to do in the future. Then you add in that he has the exact same LD percentage he had in 2008 with the Cardinals (21.0%) with a huge difference in his actual results (.343 BABIP in 2008, .236 this year). Don't get me wrong here. Miles as what he actually is (a .675 OPS guy or so with decent defense at second and poor defense at SS) is not a good option for a ballclub. But he almost certainly is a better hitter than Blanco, who is more of a .610-.615 type of guy. Whether Blanco's defense makes up for his hitting depends on how much you are going to use them at SS and how much at 2B. For the Cubs, it's mostly been at 2B, which makes Miles the slightly better option. If Theriot went down to an injury, Blanco would be the better option to replace him everyday. They are both fringe major leaguers for different reasons. Jersey does bring up one good point though. I think Miles LD percentage is going to have a hard time being in line with his BABIP because teams can cheat in and pick off line drives that would fall in for hits for other hitters (Blanco is the same way). But there's no way it should be that far off.
