Jim Bottomley set the Major League record for RBIs in a single game, with 12, set on September 16, 1924. Bottomley is also known as the only man to be sued for hitting a home run and a fan was hit by the ball when he wasn't looking. He was elected to the Baseball Hall of Fame posthumously in 1974. His single game RBI record would stand for 69 years.
On September 7th 1993 in front of 22,606 amazed spectators Mark Whiten went 4 for 5 crushing 4 home runs and racked up 12 RBIs to tie the previous record with style. Quite the feat considering he also tied the record of most home runs in one game with only 15 others which span 1896-2003.
even more fascinating in my research was when it really counted, who had the most RBIs in a single world series playoff game. the answer is Bobby Richardson, Yankees second baseman from 1955 to 1966. on Oct. 8, 1960 he accumulated 6 RBIs to set the world series single game record.
Richardson won three World Series (1958, 1961, 1962) of the seven he played with the Yankees (1957, 1958, 1960, 1961, 1962, 1963, 1964). Hardly moving from his position, he caught the final out of the 1962 Series, snaring a screaming line drive off the bat of Willie McCovey, which, if it had been two or three feet higher would have won the Series for the San Francisco Giants.
He was named World Series MVP in 1960 when he helped the Yankees against the Pittsburgh Pirates, although the Yankees lost in a Series in which normally light-hitting second basemen (the other being the Bucs' Bill Mazeroski) shone at the plate. During that Series, Richardson hit .367 with 11 hits in 30 at bats. He had a home run (a grand slam) and 12 RBIs, and also racked up two doubles and two triples in the seven-game series. To this day, Richardson remains the only World Series MVP selected from the losing team.
In the 1964 World Series against the St. Louis Cardinals, he tied a World Series record with 13 hits. However, with the Yankees losing 7-5 in Game 7, and batting against Cardinal ace Bob Gibson, he had the dubious distinction of making the final out of the Series, popping out to Dal Maxvill.
