Just some more history for you…On July 5, 1937, Joe DiMaggio of the New York Yankees hits his first career grand slam. The blast, his 20th of the season, comes in the sixth inning against George “Rube” Walberg of the Boston Red Sox, and helps the Yankees to an 8-4 win and a sweep of their doubleheader.
