Michael Joseph Piazza is an American former professional baseball catcher who played 16 seasons in Major League Baseball (MLB), from 1992 to 2007. He currently serves as the manager of the Italian national baseball team. He played most notably for the New York Mets and Los Angeles Dodgers, while also having brief stints with the Florida Marlins, San Diego Padres, and Oakland Athletics. A 12-time All-Star and 10-time Silver Slugger Award winner at catcher, Piazza produced strong offensive numbers at his position; in his career, he recorded 427 home runs—a record 396 of which were hit as catcher—along with a .308 batting average and 1,335 runs batted in (RBI).

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.
