Doesn't the "Coors Effect" only make balls go something like 4% farther? this *not to beat the glue-stick* is another argument about the mental vs physical side of the game (see Cordero as Closer thread)... but i remember a really interesting engineering word problem at school trying to calculate the range of a parabola (or in baseballspeak... the distance of a flyball) that factored in: incoming speed of pitch, force and angle of impact from bat, with the only variable being the air density the ball is traveling through. equal pitch, equal swing... turns out the extra distance you get in Colorado can be about 5 - 10 feet. this does make a lot of warning track fly balls into homers, but... it's possible that hitters love going there because they think they'll hit better there. then again we're not factoring in the oxygen content of the breath the batter is taking and how that translates to power loss in muscle expecting sea level air... but hey, that's for another class.
