According to NewsOne (via the AP):
"President Barack Obama will be in the Fox broadcast booth for Tuesday night’s All-Star game.
Fox spokesman Lou D’Ermilio said Monday that Obama will join Joe Buck and Tim McCarver for the telecast from Busch Stadium but that the inning had not yet been determined.
Obama is scheduled to throw out the ceremonial first pitch, and Cardinals first baseman Albert Pujols will be on the receiving end."
Let's just hope he throws better than he bowls.
