The history of sports is both vast and rich, thanks to the existence of so many different ones and the longevity associated with them. With so much history to cull through, Athlon Sports wanted to offer the opportunity to look back and see what memorable things happened or milestones were reached on a specific date.
With that in mind, August 9 is a day in which hockey's biggest trade took place and football returned to Cleveland.
1936: Jesse Owens won the gold medal in the 4×100-meter sprint relay, his fourth at the Summer Olympics in Berlin.
1979: Los Angeles Dodgers outfielder Dusty Baker hit a two-run double that proved to be key in a 4-3 win over the Houston Astros at Dodger Stadium. Baker is now the manager of the Astros.
1988: The Edmonton Oilers traded Wayne Gretzky, Marty McSorley, and Mike Krushelnyski to the Los Angeles Kings for Jimmy Carson, Martin Gelinas, $15 million in cash, and first-round NHL Draft picks in 1989, '91, and '93. The Oilers had won four Stanley Cups in five seasons prior to the trade.
1992: Kyle Petty won the Budweiser at The Glen at New York's Watkins Glen International.
1999: Football returned to Cleveland fans after a four-year hiatus, as the new Cleveland Browns took the field for the Hall of Fame Game at Canton's Fawcett Stadium and beat the Dallas Cowboys 20-17 in overtime. The Browns had moved to Baltimore four years earlier and became the Ravens.
2017: A cat ran onto the field at Busch Stadium with the St. Louis Cardinals down 5-4 to the Kansas City Royals in the sixth inning. However, the bases were loaded, and once the cat was caught, Yadier Molina hit a grand slam in an 8-5 win. The cat became known as Rally Cat.
