James Timothy McCarver was an American professional baseball catcher, television sports commentator, and singer. He played in Major League Baseball (MLB) from 1959 to 1980 for four teams, spending almost all of his career with the St. Louis Cardinals and Philadelphia Phillies. A two-time All-Star, he helped the Cardinals to the 1964 World Series title, batting .478 in the Series, including a three-run home run in the tenth inning to win Game 5. In 1966, he became the first catcher since the 19th century to lead the National League (NL) in triples with 13. McCarver was runner-up for the 1967 NL Most Valuable Player Award, behind teammate Orlando Cepeda, after batting .295 and leading NL catchers in assists and fielding percentage.

Catcher is a position in baseball and softball. When a batter takes their turn to hit, the catcher crouches behind home plate, in front of the (home) umpire, and receives the ball from the pitcher. In addition to this primary duty, the catcher is also called upon to master many other skills in order to field the position well. The role of the catcher is similar to that of the wicket-keeper in cricket.
