What is the record for most runs scored by one team in a single inning?

On August 30, 1953, the Boston Red Sox pounded the Detroit Tigers for 17 runs in the seventh inning en route to a 23-3 shellacking. The normally light-hitting Sox sent 23 men to the plate using 14 hits, 6 walks, and, surprisingly, no errors. Every run was earned. This offensive explosion was engineered without the greatest run producer on the team (and one of the greatest in history), Ted Williams, who spent the majority of that season as a Korean War pilot. Outfielder Gene Stephens, ironically Williams’ replacement in left, had three hits in the inning, setting another record which still stands.
