IMMACULATE INNINGS
Pitchers With EXACTLY 9 Pitches — ALL 9 ARE STRIKES — in an Inning

Immaculate innings: 3 strikeouts on 9 pitches
Three up, three down, with all three batters struck out on three pitches each.
While the "immaculate inning" isn't nearly as rare as it once was -- there were none from 1929-52 and seven alone in 2022 -- any pitcher who can plow through a big league lineup on nine straight strikes deserves a special place in the record book.
"I've been pitching seven or eight years, and I just [didn't] know what [an immaculate inning] is," Dodgers closer Kenley Jansen said after tossing one in 2017. "But now I know, and it's awesome."
