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, May 5 is a day in which baseball saw its first perfect game of the modern era and three legendary NBA playoffs moments were etched in Boston Celtics history.
1904: Boston Americans pitcher Cy Young struck out eight and pitched a perfect game against the Philadelphia Athletics at Boston's Huntington Avenue Grounds. This was the first perfect game of the modern baseball era and was part of a run in which Young pitched a record 25.1 consecutive hitless innings.
1969: Boston Celtics forward Don Nelson threw up a jump shot that hit the back of the rim and bounced up in the air before going in to give the Celtics 105-102 lead over the Los Angeles Lakes in Game 7 of the NBA Finals at The Forum. The aging Celtics held on to win 108-106 in one of the biggest upsets in NBA history.
1981: Trailing the Houston Rockets 87-84 in the fourth quarter of Game 1 of the NBA Finals, Boston Celtics forward Larry Bird rebounded his own jump shot and put it in the basket before falling out of bounds. The win propelled Boston to a 98-95 win at the Boston Garden and the Celtics went on to win the Finals in six games.
1991: Larry Bird suffered a concussion in the second quarter of Game 5 of the first round of the NBA playoffs against the Indiana Pacers. However, he returned in the third quarter to an elated Boston Garden crowd and led the team to a 124-121 victory.
1992: A terrace at Armand Cesari Stadium collapsed during a French Cup semifinal match between SC Bastia and Olympique de Marseille, killing 18 people and injuring more than 2,300.
2007: Floyd Mayweather Jr. won the WBC Light Middleweight title with a split decision over Oscar De La Hoya at Las Vegas' MGM Grand Garden Arena. The fight set a then-record of 2.4 million pay-per-view buys.
2018: Justify beat Good Magic by two and a half lengths to win the Kentucky Derby. The horse went on to win the Triple Crown.
