It's been a while since I've posted something like this. Everything is relative to average, except for Total RAR which uses zero as replacement level. Replacement runs (blue) are flipped underneath the zero line to separate the lines and because they represent where a replacement level player in the same number of PAs would fall relative to average.
Placido Polanco has beeen average or above in every category except batting in 2006. He was worth about 1.5 wins above replacement that season, but has been between three and five WAR every other season. Pretty quietly, too. Four WAR is about All-Star caliber. In 2009, he's nearing the one WAR mark, making him about average.
