Yesterday, Buster Posey and Madison Bumgarner of the Giants became the first batterymates to hit  grand slams in the same game.  Bumgarner is also the 1st pitcher to hit two slams in a season since 1966, when Tony Cloninger hit two in one game for the Braves against, coincidentally, the Giants.

Loads of trivia and statistics are two of the many reasons that I am such an ardent baseball fan.
