Alex Rodriguez hit his first homerun against Kansas City in 1995. Then, he smacked his 500th against Kyle Davies of the Royals in 2007. He had a chance to hit No. 600 against the same team (and Davies) when the Royals visited the Stadium about two weeks ago.
Well, that didn't work out but we discovered that Sean Marcum, the Toronto pitcher who yielded No. 600, was born in Kansas City.
