If you have watched a Major League Baseball game go to extra innings in the last few years, you have seen something that would have baffled fans a decade ago: the moment the 10th inning begins, a runner is suddenly standing on second base, even though nobody hit, walked, or reached. This is the “ghost runner,” and it is one of the most significant, and most debated, rule changes in modern baseball.
Officially called the automatic runner or designated runner, the rule places a free runner on second base to start each half-inning of extra innings during the regular season. It was born out of necessity during the pandemic-shortened 2020 season, stuck around through 2021 and 2022, and was made permanent in 2023. The goal is simple: end games faster and spare pitching staffs the grind of marathon extra-inning battles.
The chart below is a complete breakdown of the ghost runner rule, how it works, who the runner is, how it affects the stats, its full history, the strategy it creates, and where it does and does not apply. Take a look, then we’ll get into the details.

What the ghost runner rule actually is
The ghost runner rule, known officially as the automatic or designated runner, is straightforward once you see it. When a regular-season game is tied after nine innings and heads to extras, each team begins its turn at bat with a runner already standing on second base, no outs. That runner did not earn his way on; he is placed there automatically to manufacture a scoring chance and push the game toward a quicker conclusion. The same setup repeats at the start of every subsequent extra inning until someone wins.
The intent is to break ties faster. Before the rule, extra-inning games could stretch to 15, 18, or even more innings, exhausting bullpens and occasionally forcing position players to pitch. By starting each half-inning with a runner in scoring position, MLB dramatically increased the odds of a run, and therefore a swift resolution. The data backed it up: average extra-inning game length dropped, and the marathon affairs largely disappeared.
Who exactly is the ghost runner
A common question is who gets to be the free runner. The rule specifies that it is the player in the batting order immediately preceding that half-inning’s leadoff hitter. In plain terms, that is almost always the man who made the final out of the previous inning. If the No. 7 hitter is due to lead off the 10th, then the No. 6 hitter trots out to second base to start the inning.
Teams are allowed to substitute a pinch-runner for that player, and they frequently do. Since the runner is already in scoring position, speed becomes valuable, so a manager will often replace a slow slugger with the fastest player on the bench, hoping to score on a single, a passed ball, or even a stolen base. This small substitution decision has become one of the subtle new strategic wrinkles the rule introduced.
How it changes the box score
The ghost runner creates some quirks in the statistics, all designed to keep the numbers fair. If the automatic runner comes around to score, the run counts on the scoreboard, but it is recorded as an unearned run, so it does not hurt the pitcher’s ERA. The logic is sound: the pitcher never actually allowed that runner to reach base, so it would be unfair to charge him for it.
For the runner himself, the play is a statistical ghost in another sense. He is credited with a run scored if he comes home, but he is not charged with a plate appearance or a time on base, meaning his on-base percentage is untouched. Meanwhile, the batter who drives him in does receive a legitimate RBI. These accounting rules ensure the automatic runner does not artificially distort individual players’ season numbers.
From pandemic fix to permanent fixture
The rule’s path to permanence is a story of a temporary fix that stuck. MLB first deployed the automatic runner in the 60-game 2020 season, purely as a health and safety measure, the league wanted to shorten games and limit pitcher workloads after an abruptly interrupted spring training. It was meant to be temporary, but the league liked the results and kept it through 2021 and 2022 as an ongoing trial.
In 2023, MLB’s competition committee voted unanimously to make the rule permanent for the regular season. The concept was not even new to baseball: a version of the extra-innings tiebreaker had been used by international baseball’s governing body, in the Olympics and the World Baseball Classic, for decades, and the minor leagues had experimented with it as well. What began as a pandemic stopgap is now a settled, everyday part of the major-league game.
Where the rule does and does not apply
The single most important exception is the postseason. In the playoffs, the ghost runner disappears entirely, and extra innings revert to traditional, runner-free baseball of unlimited length. MLB drew this line deliberately: with championships on the line, the league wanted the highest-stakes games decided by conventional play rather than a manufactured tiebreaker. So a October classic can still theoretically go 18 innings, even as a July game cannot.
Beyond MLB, the rule is widespread. The minor leagues use it, international competitions have employed versions of it for years, and college baseball offers it as an optional tiebreaker format. This broad adoption is part of why the rule, controversial as it remains among purists, has come to feel like an established feature of the modern game rather than a passing experiment.
The strategy and the debate
The ghost runner has reshaped late-game strategy. With a runner on second and nobody out, the team batting will often bunt him to third to set up a sacrifice fly, deploy a speedy pinch-runner, or play aggressively for a single run. The defense, in turn, may bring the infield in to cut down the runner at home and will pitch carefully to avoid the walk that compounds the danger. Managers also tend to use their best relievers earlier, knowing a game can end in a single half-inning.
It remains divisive. Supporters, including many within the game, praise it for ending the war-of-attrition marathons that wrecked bullpens and dragged late into the night. Critics, often nicknaming it the “Manfred Man” after the commissioner who championed it, argue it cheapens extra innings by handing teams a runner they did not earn. Whether you love it or hate it, the rule is here to stay, and understanding it is now essential to following any extra-inning game.
Final Word
The ghost runner rule places an automatic runner on second base to start each half-inning of regular-season extra innings, a change designed to end tie games faster and protect pitching staffs. Born as a pandemic measure in 2020 and made permanent in 2023, it has succeeded at its core goal: extra innings are shorter, marathon games are rare, and bullpens are spared. The runner is the man who made the last out (or a pinch-runner), his run counts but is unearned, and the rule applies everywhere except the MLB postseason.
Love it or hate it, the automatic runner is now a permanent part of how baseball breaks a tie, and it has quietly introduced a whole new layer of late-game strategy. For more on baseball’s distinctive moments, see our explainer on what a walk-off is.
