Roy Campanella
set single-season records for catchers with 41 home runs and 142 RBI's in 1953. His home run record lasted until 1996. He was a member of five World Series teams, played in eight All-Star games, and was the National League MVP three times.

Alexander Joy Cartwright, Jr.
is considered the "Father of Baseball" by the National Baseball Hall of Fame. According to the story, he was responsible for drafting the first set of formal rules for the game in 1845, and for spreading his love of the game across the country and into Hawaii.

(William) Roger Clemens
became the first pitcher in history to strike out 20 batters in a nine-inning Major League game in 1986. In 1996, he became the only pitcher in Major League history to strike out 20 batters twice. In 2003, he became the only player in Major League history to score his 300th win and 4,000th strike-out in the same game.

Dwight Eugene Gooden
became the youngest All-Star selection in baseball history in 1984 (he was 19), and in 1985 became the youngest-ever recipient of the Cy Young award.

Sanford "Sandy" Koufax
was a left-hander who enjoyed a five-year stretch as perhaps the most dominating pitcher in the history of baseball.

Connie Mack
holds the record for most games managed by one man, the most wins as a manager, and the most losses as a manager. As a manager, he was known for preferring a business suit instead of a uniform, and for always calling his players by their given names, never by their nicknames.

Mickey Charles Mantle
became the highest played active player in the major leagues when he signed a $75,000 contract in 1961. Although his career was frequently interrupted by injury, he managed to smash 536 home runs and compile a .298 batting average. He still holds records for the most World Series home runs, RBI's, runs, walks, extra-base hits, and total bases.

Satchel Paige
was 42 years old when, in 1948, he became the first black pitcher in the American League.

is the only Major League baseball player to date to be named Most Valuable Player in both the National and American Leagues. He is also the only player ever to hit a fair ball completely out of Baltimore's Memorial Stadium, and was the first black manager of a Major League team.

George Herman "Babe" Ruth Jr.
developed his baseball skills at a reform school. He began his professional career as a pitcher, but is best known for his prowess as a batter. His regular season record of 714 home runs would not be exceeded until Hank Aaron hit his 715th in 1974, and his lifetime slugging average of .690 has never been approached.
