Great Baseball Moments- Fred Lynn Hits The Only Grand Slam in All-Star Game History. It was the fiftieth anniversary of the inaugural All-Star Game in 1933- and it was played in the very same ball park- old Comiskey Park in Chicago. It’s kind of hard to believe in 2021- after 90 All-Star Games have been played that there has only been one grand slam home run hit in All-Star Game history. It happened in the bottom of the 3rd inning. Atlee Hammaker was pitching for the National League- Fred Lynn of the California Angels who always seemed to come up big in All-Star Games- he hit a total of four second only to Stan ‘The Man’ Musial. Lynn’s home run ignited a 7 run third inning for the American League and led them to a blow out 13-3 victory. The National League had won 11 straight All-Star Games- the last American League win had been back in 1971.
