Fernando Tatis of the St. Louis Cardinals becomes the first player in major league history to hit two grand slams in one inning. Tatis connects both times in the 11-run 3rd inning against pitcher Chan Ho Park to lead the Cardinals to a 12 – 5 rout of the Los Angeles Dodgers. He simultaneously sets a record with eight RBI in one inning. Park becomes the first pitcher in the 20th century, and only the second ever, to surrender two slams in a single frame, joining Bill Phillips of the 1890 Pittsburgh Alleghenys.
