What is an Immaculate Inning?

Last Updated on

Imagine the feeling of 9 straight strikes and three straight outs?

One of the coolest baseball terms in the game, the Immaculate Inning is so stunning that it comes out of nowhere. There's no rhyme or reason to it. For instance, the Chicago Cubs had a string of them in the 70s. The Detroit Tigers went back-to-back in the 50's and haven't seen one since. The San Francisco Giants have thrown three, and you'd have thought all three belong to Orel Hershiser, a pitcher with legendary control. But no, he only had the one in 1998 against the Rockies.

The six that belong to the Milwaukee Brewers didn't start until the 1990s, and the Texas Rangers, well they just don't exist in the charts. Perhaps hitters are just more patient in the Lone Star state. Or maybe it's just warm weather, as the Padres just have one.

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.

What circumstances increase the chances of throwing an Immaculate Inning?

This is purely a guess, but we believe that a few key factors help to increase the likelihood of a pitcher throwing an Immaculate Inning. We haven’t consulted the Baseball Almanac or baseballreference.com for the stats, but here’s our hunch.

When was the most recent Immaculate Inning?

Funny enough, the most recent Immaculate Inning was pitched by Luis Garcia of the Houston Astros on June 15th, 2022. Why is that funny? It’s funny because Garcia’s teammate, Phil Maton threw one just a few innings earlier. The rosin bag must have been hot that night.

But get this, both pitchers threw their Immaculate Innings against the very same batters in the lineup. The SAME batters (below). Tough night, bros.

Who pitched the last Immaculate Inning before 6/15/22?

The last Immaculate Inning prior to the June 15th Houston game was thrown by Nestor Cortes of the New York Yankees on April 17th, 2022. Cortes sent Robinson Chirinos, Chris Owings and Kelvin Gutiérrez and packing on nine straight in the 8th.
