Henry Ramón Blanco is a Venezuelan professional baseball coach and former player. He is currently the catching and strategy coach for the Washington Nationals. He played as a catcher in Major League Baseball from 1997 to 2013, appearing for the Los Angeles Dodgers, Colorado Rockies, Milwaukee Brewers, Atlanta Braves, Minnesota Twins, Chicago Cubs, San Diego Padres, New York Mets, Arizona Diamondbacks, Toronto Blue Jays, and Seattle Mariners. He later served as quality assurance coach for the Cubs. Although a light-hitting player, he was regarded as one of the best defensive catchers in Major League Baseball.

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.
