Víctor Jesús Martínez, also known by his nickname "V-Mart", is a Venezuelan former professional baseball designated hitter and catcher. Martínez played in Major League Baseball (MLB) for the Cleveland Indians, Boston Red Sox, and Detroit Tigers. After joining the Tigers, he played mostly as a designated hitter.

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.
