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, April 21 is a day on which a future Dallas Cowboys starting quarterback (and current NFL color commentator for CBS Sports) was born and a future Hall of Fame reliever became the first to reach a milestone for saves.
1925: Flags began flying at half-mast in Major League ballparks for a month in honor of Brooklyn Dodgers majority owner and president Charles Ebbets who died of heart failure on April 18.
1956: The New York Yankees blew an eight-run lead but scored five runs in the bottom of the eighth inning to beat the Boston Red Sox 14-10 at home.
1972: The New York Knicks and Boston Celtics brawled with a little over a minute to play in the Knicks' 116-98 win at Madison Square Garden in Game 4 of the Eastern Conference Finals.
1980: Tony Romo was born in San Diego. After a great career at Eastern Illinois, he was the Dallas Cowboys' starting quarterback for 10 seasons and is now one of the most popular broadcasters working today.
1982: Milwaukee Brewers relief pitcher Rollie Fingers became first to record 300 saves in a 3-1 win over the Toronto Blue Jays at Milwaukee County Stadium.
1984: Bob Knight made his first cut of players for the 1984 Olympic men's basketball team. Surviving players included Michael Jordan, Patrick Ewing, Sam Perkins, John Stockton, and Karl Malone. Stockton and Malone would eventually be cut, while Jordan, Ewing, and Perkins made the final roster.
1996: Famed bookmaker and NFL Today sports commentator Jimmy "The Greek" Snyder died of a heart attack in Las Vegas at the age of 77.
2001: The Los Angeles XTreme beat the San Francisco Demons 38-6 in the XFL Championship. The league folded less than three weeks later.
2013: Matt Kenseth won the STP 400 at the Kansas Speedway in Kansas City, Kansas.
