When was the last time each MLB team had a pitcher throw an immaculate inning?

A rare achievement treasured by pitchers, the immaculate inning has become much more frequent in recent seasons.

Perhaps one of the coolest characteristics of baseball is that there are seemingly an infinite amount of ways to carve out a niche and succeed in a player’s own way – with the approach to pitching serving as a pertinent example.

While pitchers of today have gone even deeper in specializing their craft, mastering upwards of four-to-five pitches, pitching styles are typically defined on a power-to-control spectrum – with some pitchers placing a heavier emphasis on fastball velocity while others make their name with a filthy offspeed pitch instead.

The differences expand from there – with both power and control pitchers further differing on whether they predominantly pitch to contact or aim to induce swings and misses. For pitchers who prioritize the latter, one single-game accomplishment stands out as a lofty goal.

The best strikeout pitchers can prove the extent of their dominance by tossing an immaculate inning, where all three batters of an inning are retired on three-pitch strikeouts. The final result is a nine-pitch, three-strikeout inning that has only occurred 117 times in MLB history, with 109 different pitchers accomplishing the feat.

There have been five different pitchers to accomplish the feat more than once – Sandy Koufax, Nolan Ryan, Chris Sale, Max Scherzer and Kevin Gausman. Of those, Koufax, Sale and Scherzer have pitched an immaculate inning on three different occasions.

Though the immaculate inning remains a good deal more rare than the no-hitter or hitting for the cycle, the frequency of immaculate innings has greatly skyrocketed in recent years as strikeouts across the game have increased at a similarly rapid rate.

After just 29 immaculate innings between 1990 to 2009, there have been twice as many that have occurred since the start of the 2010 season – with 37 immaculate innings in the 2010’s and 21 immaculate innings thus far in the 2020’s.

While it seems the achievement has lost a little bit of rarity in recent years, the Texas Rangers and Minnesota Twins remain the only two franchises to have never had a pitcher throw an immaculate inning, each outlasting four expansion franchises from the 1990’s.

After the 2023 and 2024 seasons saw two immaculate innings thrown apiece, four different pitchers recorded the achievement during the 2025 – two of which were thrown by starters and the other two thrown by late-inning relievers.
