12. Fernando Tatis Hits Two Grand Slams—In One Inning

April 23, 1999 was a bad day for pitcher Chan Ho Park. He loaded the bases twice in the third inning, and both times one single solitary batter knocked them out of the park. That man was Fernando Tatis, a player who had only 23 career home runs heading into the game. That day he also set the record for eight runs batted in during an inning. For an idea of just how rare this is, Derek Jeter needed 6,542 tries to hit his first grand slam. Tatis’ Cardinals won the game, unsurprisingly, 12-5. And Park left the field with an unfortunate record of his own.
