In baseball, a no-hitter is a game in which a team was not able to record a single hit. Major League Baseball (MLB) officially defines a no-hitter as a completed game in which a team that batted in at least nine innings recorded no hits. A pitcher who prevents the opposing team from achieving a hit is said to have "thrown a no-hitter". This is a rare accomplishment for a pitcher or pitching staff: only 299 have been thrown in Major League Baseball history since 1876, an average of about two per year. In most cases in MLB, 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. The most recent no-hitter by a single pitcher was thrown on May 8, 2018 by James Paxton of the Seattle Mariners against the Toronto Blue Jays at Rogers Centre. The most recent combined no-hitter was thrown on May 4, 2018 by Walker Buehler, Tony Cingrani, Yimi Garcia, and Adam Liberatore of the Los Angeles Dodgers against the San Diego Padres at Estadio de Béisbol Monterrey.
