List of Major League Baseball single-game runs scored leaders
In Major League Baseball, players have scored six or more runs in one game 17 times. This record has been achieved by 16 players, the most recent being Nick Kurtz of the Athletics on July 25, 2025. Mel Ott is the only player to accomplish the feat twice, doing so nearly a decade apart.
Three players — Ott, Cap Anson, and King Kelly — have been elected to the Baseball Hall of Fame. A player's team has never lost a game in which he scored six runs. Only one of the players who have scored six runs are currently active in MLB.
Guy Hecker scored seven runs for the Louisville Colonels against the Baltimore Orioles in the American Association which was one of the two Major Leagues at the time, on August 15, 1886, setting the record for professional baseball. Hecker is also the only pitcher to score as many as six runs in a game. In addition, Hecker collected six hits, another unique accomplishment for a pitcher.
Shawn Green's six run game set the Major League record for total bases and tied the Major League records for home runs and extra-base hits. These records were tied by Nick Kurtz.
Six players on this list also collected six hits on their way to scoring six runs: King Kelly, Ginger Beaumont, Edgardo Alfonzo, Shawn Green, Joe Randa, and Nick Kurtz.
The record for runs in a postseason game is five.
