The most interesting thing to come out of spring training so far

Does anybody know what is up with the new spring training uniform design that changes colors underneath players' armpits? I first saw it on some footage of Japanese ace Daisuke Matsuzaka and thought perhaps that the massive force used to propel his gyroball also led to massive sweat (because, as they say, with great responsibility comes great perspiration).

But then I saw every player had these built-in armpit stains during the Red Sox-Twins spring training opener Wednesday night, which ended in a thrilling 4-4 tie. The Sox had blue stains on their red uniform tops; the Twins had red stains on their blue uniform tops.

If I had to guess, I would say the armpit patch is made from a different material and it allows fat players arms to rotate more easily.

Either way, new shortstop Julio Lugo is downright ecstatic about the change. Take a look for yourself.
