Mariners fans have grown accustomed to Richie Sexson (240 pounds, .216 average) achieving this rare phenomenon and Dodgers fans pretty much expected Andruw Jones (240 pounds last time anyone checked, .165 average) to be awful. (note: Chin-Lung Hu can probably be included in this category but he will be spared the humiliation of publication of either his weight or batting average).
But nobody really expected this from Ryan Howard. Howard is a big guy, weighing 256 pounds, so if he were hitting .240 nobody would care. However, his .208 batting average is embarrassing no matter how you look at it. Howard is a career .280 hitter and has made serious runs for the MVP award the last two years, so this is surprising and a huge concern to the Phillies.
