In baseball, a batter can reach first base with a hit, or by being walked with four balls.
He also goes to first if he is struck by a pitch or if the catcher interferes with his at bat.
If the catcher drops the ball on strike three or the pitcher throws the ball out of the playing area the batter moves to first.
Finally, the seventh way a batter can get on base is if the baseball becomes stuck in the umpire’s mask or equipment.
