Aníbal Alejandro Sánchez Jr. is a Venezuelan former professional baseball pitcher. He made his Major League Baseball (MLB) debut in 2006 with the Florida Marlins and also played for the Detroit Tigers, Atlanta Braves, and Washington Nationals. On September 6, 2006, in his 13th career Major League start, Sánchez pitched a no-hitter against the Arizona Diamondbacks.

In baseball, a no-hitter or no-hit game is a game in which a team does not record a hit through conventional methods. Major League Baseball (MLB) officially defines a no-hitter as a completed game in which a team that batted in at least nine complete innings recorded no hits. A pitcher who prevents the opposing team from achieving a hit is thereby said to have "thrown a no-hitter". In most cases, no-hitters are recorded by a single pitcher who throws a complete game; one thrown by two or more pitchers is a combined no-hitter.
