Scoring double-digit runs in an inning is not something you see very often. The 1930 season was the highest scoring one in the World Series era, and even then that year only saw teams score an average of 5.49 runs per game. If you go to a game today, there’s a very good chance you won’t see 10 runs total, never mind from one team in one inning.
Due to all that, if a team does manage the feat of scoring 10 or more runs in an inning, you can reasonably expect that team to win the game.
