Happy Fourth of July.

As we scarf down hot dogs and hamburgers, we are reminded of the history of America, from our humble beginnings as Pilgrims on the Mayflower, to today, when so many historic moments are happening.

A big part of America’s history has played out through sports, such as the Bambino’s called shot and Joe Namath’s guarantee in Super Bowl III. What follows are five moments that happened on this date that changed the sports world.

1984—The King Wins his Last Race

With President Ronald Reagan in attendance, the first sitting president to attend a race, Richard “The King” Petty won his 200th and last NASCAR race, the Firecracker 400 at Daytona.

In a race that would be shortened because of Doug Heveron’s crash on lap 158, Petty edged out Harry Gant for the victory in a one-lap shootout. Most people believe that Petty beat out Cale Yarborough, but Yarborough mistakenly went into pit road too early and finished third.

Petty didn’t go to Victory Lane afterward, but went straight to the press box to meet the president.

Petty would race for another eight years, but would never win another race. To commemorate his final victory, his number 43 car now sits in the Smithsonian.

Whether or not he won another race, this would always be one of Petty’s most memorable wins.

1910—The Fight Of The Century

On this date, boxer James Jeffries came out of a six-year retirement and put his undefeated record on the line to face Jack Johnson in Reno, Nevada.

When asked why he was going to do it, Jeffries said, "I am going into this fight for the sole purpose of proving that a white man is better than a Negro." Obviously, there was a lot of racial tension, egged on by the promoters who incited the all-white audience to “kill the ______.”

Johnson shut them all up, knocking down Jeffries twice for the first time in his career. His cornermen called it quits in the 15th round, to prevent Jeffries from being knocked out.

Johnson would earn $225,000 from the fight, and finally received the recognition from the critics, who called his victory over Tommy Burns “empty.”

1976—McCarver Makes the Bicentennial Memorable in Pittsburgh

On America’s Bicentennial, the future broadcaster would become the only person in major league baseball to blow a grand slam home run as a hitter.

In a game on this date, McCarver hit what was supposedly the game winning grand slam against Pittsburgh. During his trip around the bases, he passed teammate Gary Maddox. The confused umpires awarded McCarver a grand slam single.

Later, as host of the HBO series “The Not-So-Great Moments in Sports,” McCarver would claim that “I didn’t pass [Maddox], he lapped me.”

When asked how he could do that, McCarver replied, “Sheer speed.”

1934—The Brown Bomber Goes Professional

 On this date, Joe Louis made his professional boxing debut on Chicago’s South Side.

After winning a national amateur championship, he fought against Jack Kracken, who was making his last appearance in the ring. Louis bid farewell to Krac
