Lawrence Peter "Yogi" Berra was a former American Major League Baseball catcher, outfielder, and manager. He played almost his entire 19-year baseball career (1946-1965) for the New York Yankees. Berra was one of only four players to be named the Most Valuable Player of the American League three times and is one of only six managers to lead both American and National League teams to the World Series. As a player, coach, or manager, Berra appeared in 21 World Series. He was elected to the Baseball Hall of Fame in 1972.

Berra is widely regarded as one of the greatest catchers in baseball history. According to the win shares formula developed by sabermetrician Bill James, Berra is the greatest catcher of all time and the 52nd greatest non-pitching player in major-league history.

Berra, who quit school after the eighth grade, has a tendency toward malapropism and fracturing the English language. "It ain't over till it's over" is arguably his most famous example, often quoted. Simultaneously denying and confirming his reputation, Berra once stated, "I really didn't say everything I said."
