What is an Immaculate Inning?

One of the coolest baseball terms in the game.

What constitutes an Immaculate Inning?

An Immaculate Inning is when a pitcher, at any level, throws 9 straight strikes to 3 consecutive batters, resulting in 3 strike outs. This also qualifies the pitcher for having struck out the side.

The cool thing about this unique baseball term is that it can happen at any moment, yet it is stunningly rare. In fact, more No Hitters have been thrown in MLB history than Immaculate Innings, with a total of 316 No-Hitters to 108 Immaculate Innings.

Essentially, no-hitters are 3x more likely to occur, despite a pitcher having to pitch at least 5 innings in an official rain out, 8 innings in a full game where he was on the home team, and 9 innings (in general) to be counted.

Further, whereas plenty of Hall of Fame caliber players (starters) have tossed a no-no, an Immaculate Inning is a wildcard when it comes to talent. They’ve been thrown by every type of pitcher in Baseball History, including journeyman relievers through HOF starters and beyond. Given that though, only world class talent seems to be able to repeat the feat, as most of the people who have thrown multiple Immaculate Innings are in the Hall of Fame.

Major League history contains an inordinate amount of statistics, but this is one of the rarest occurring scenarios.
