How the hell would that make him less of an American? Baseball is boring as hell to watch and takes considerable skill, luck, and practice to play effectively. Why should one play it if one doesn't enjoy it? Apple pie is awesome but I could certainly understand someone with an aversion to sweets abstaining from it.
I agree that baseball is about as exciting as watching paint dry, and I haven't played baseball since I was in high school (and then only at an intramural level). Nonetheless, I could walk on a field tomorrow and at least manage to put a pitch into the catcher's glove. It probably wouldn't be a strike, but it wouldn't have a trajectory straight out of slow pitch softball, I can promise you that.
Did you watch his legs? He definitely throws like a girl. And not just any girl -- a girl who has never played baseball.
