Nobody has ever stolen all four bases in a single inning of professional baseball. Stealing first base isn't a recognized feat. It happens occasionally when a strikeout goes wild and the player sprints to first, but it's not officially counted as a "steal."

However, several players have come tantalizingly close:

Stealing Second, Third, and Home: This rare feat has occurred 19 times in MLB history, with greats like Ty Cobb achieving it three times. The most recent instance was by Elly De La Cruz in July 2023.


Three Stolen Bases in a Row: This is much more common, happening almost weekly in MLB. However, it requires the runner to be on base without hitting (walk, error, etc.), making it less impressive than stealing all four starting from first.


How likely is it to happen in the future? Stealing all four bases in one inning remains highly unlikely. It requires a combination of:

Elite base-stealing skill: The runner needs to be exceptionally fast and adept at reading pitchers and catchers.


Open bases: No outs or only one out is preferred, with no runners ahead to force throws to other bases.


Defensive inattention: Pitchers and catchers must be caught off guard, either by the runner's timing or a distraction.


Given the confluence of factors needed, it's safe to say stealing all four bases in one inning will remain a legendary feat in baseball history.

Interestingly, some minor leagues have experimented with "leadoff steals" to encourage more base stealing. In this format, a runner automatically starts on second base in extra innings. While this hasn't led to any four-base thefts, it does highlight the continued intrigue surrounding base stealing in the game.
