July 12, 1901: Cy Young notches his 300th career win, as the Boston Americans defeat the Philadelphia Athletics 5-3.

In the game that took place at Huntington Grounds in Boston, Young, 34, gave up seven hits on the game.

Denton True Young gained his nickname "Cy" when somebody referred to his powerful fastball that destroyed fences as a cyclone.

In an era without closers, a 5-man rotation and a bullpen, Young won 211 more games after getting his 300th. The 511 wins throughout his 22-year career is undoubtably one of the most unbreakable records in all of sports. Walter Johnson is the only other pitcher to surpass 400 wins (417).

Young became the seventh player to reach 300 wins. The previous six pitchers (whom played predominantly in the late 1800's) to reach the milestone were: Pud Galvin, Tim Keefe, Mickey Welch, Charley Radburn, John Clarkson and Kid Nichols.

In addition to the most wins, Cy Young's 7,354 innings pitched are significantly greater than any other pitcher. Nolan Ryan pitched until he was 46, and he was still just under 2,000 innings short of Young.

Young's 316 losses, 749 complete games and 815 games started are also major league records.

Young won 30 games in a season five times, and had ten more seasons with at least 20 wins. He pitched the fourth ever perfect game in baseball (the first of the "modern era").

In honor of his incredible career, the MLB created the Cy Young Award in 1956, given to the best pitcher each season.
