A perfect game in baseball is the sport's rarest pitching achievement: a pitcher must face exactly 27 batters and retire all 27, allowing zero baserunners by any means. In over 238,500 Major League Baseball games played since 1876, only 24 perfect games have ever been recorded — a probability of roughly 0.01%.
The most recent belongs to Domingo Germán of the New York Yankees, who accomplished the feat on June 28, 2023, against the Oakland Athletics. This achievement stands above even the no-hitter because it demands absolute flawlessness: no hits, no walks, no errors, no hit-by-pitches — nothing but 27 consecutive outs.
Understanding a Perfect Game: Definition and Requirements
A perfect game requires a starting pitcher to throw a complete game, while retiring every batter faced. Weather-shortened games of fewer than nine innings do not qualify, regardless of how dominant the performance.
To achieve perfection, the pitcher must prevent baserunners through any means, including:
- Hits (singles, doubles, triples, home runs)
- Base on balls (walks)
- Hit by pitch
- Errors or fielder's choice
While the pitcher receives credit, a perfect game is truly a team achievement. Every fielder must execute flawlessly. A dropped fly ball, a throwing error, or any defensive miscue ends the bid. The defense behind the pitcher plays an equally critical role in preserving perfection through 27 consecutive outs.
Difference Between No-Hitter and Perfect Game
The key distinction is simple: every perfect game is a no-hitter, but not every no-hitter is a perfect game.
In a no-hitter, the pitcher allows zero hits but may still permit baserunners through walks, errors, hit batters, or other means. A perfect game demands absolute perfection — no baserunners of any kind for nine innings. One walk, one error, one hit batter, and the perfect game bid ends, though the no-hitter can continue.
Edwin Jackson's 2010 no-hitter for the Arizona Diamondbacks illustrates this perfectly. Jackson walked eight batters, and his defense committed two errors, yet he still earned a no-hitter because no Tampa Bay batter recorded a hit. Under perfect game standards, his performance would have ended in the first inning.
The rarity gap is dramatic. MLB history includes over 300 documented no-hitters — roughly two per season on average. Perfect games? Just 24 in nearly 150 years.
A related but distinct achievement is the shutout, where a pitcher allows no runs but may surrender hits and baserunners. It ranks below both no-hitters and perfect games in difficulty.
Perfect Game Statistics and Records
Across 24 perfect games, certain statistical patterns emerge that reveal just how varied and remarkable these performances can be. Every perfect game requires a minimum of 27 batters faced and nine innings pitched, but pitch counts have ranged dramatically. Addie Joss set the efficiency standard in 1908, needing just 74 pitches to retire all 27 Cleveland batters. At the other extreme, Matt Cain of the San Francisco Giants threw 125 pitches during his 2012 gem against the Houston Astros — the most in any documented perfect game. Cain also recorded 14 strikeouts, tying Sandy Koufax for the most in a perfect game and illustrating that dominance can come through power or precision.
Team records tell their own story. The New York Yankees lead all franchises with four perfect games, while the Chicago White Sox have produced three. On the receiving end, the Tampa Bay Rays have allowed three perfect games. The catcher's role proves crucial in these achievements: Ron Hassey remains the only catcher in MLB history to catch two perfect games, doing so with Len Barker in 1981 and Dennis Martínez in 1991.
The distribution by handedness favors right-handed pitchers (16) over left-handers (8), though southpaws like Koufax and Randy Johnson delivered some of the most dominant performances. Johnson holds the age record, throwing his perfect game at 40 years old in 2004.
The 2012 season stands alone in modern history. Philip Humber, Matt Cain, and Félix Hernández of the Seattle Mariners each threw perfect games within a four-month span — the only season to produce three. Meanwhile, the longest drought stretched 13 years between 1968 and 1981, when Len Barker finally broke the silence. These streaks and gaps underscore how unpredictable perfection remains, even as pitchers face hitters with career batting averages well above .250.
Famous Perfect Game Near-Misses and Controversies
Baseball history includes heartbreaking near-misses — none more infamous than Armando Galarraga's "imperfect game."
On June 2, 2010, the Detroit Tigers pitcher retired 26 consecutive batters before Jason Donald grounded to first baseman Miguel Cabrera. Galarraga covered the bag in time, but umpire Jim Joyce called Donald safe. Replays confirmed the error immediately. Joyce, devastated, offered a tearful public apology; Galarraga responded with remarkable grace.
The incident became a catalyst for MLB's expanded instant replay system, implemented in 2014 — ensuring future perfect games wouldn't be lost to human error.
Perfect Game Trivia and Lesser-Known Facts
Has anyone thrown two perfect games? No pitcher has ever achieved perfection twice — though Nolan Ryan threw seven no-hitters without a single perfect game.
Is a 27-pitch perfect game possible? No. Even striking out every batter on three pitches requires 81 pitches minimum.
Has anyone caught multiple perfect games? Only Ron Hassey, behind the plate for both Len Barker (1981) and Dennis Martínez (1991).
Can relief pitchers earn a perfect game? No — a save situation requires inherited baserunners or a close score, disqualifying perfection.
The Modern Challenge of Perfect Games
The 11-year gap between Félix Hernández's 2012 perfect game and Domingo Germán's 2023 achievement reflects profound changes in how baseball is played.
Modern hitters embrace the three-true-outcomes approach: home runs, strikeouts, or walks. This power-focused mentality means even weak contact can leave the park, and patient at-bats drive up pitch counts. Starting pitchers now face batters hunting fastballs while also navigating expanded pitch arsenals — sliders, split-finger fastballs, and cutters demand more pitches per at-bat.
The starting pitcher's role has fundamentally changed. Pitch count limits and specialized bullpens mean few starters see the ninth inning regardless of performance. A dominant pitcher through seven innings is often replaced by a relief pitcher to "preserve the arm" — a strategy that prioritizes season-long health over individual game heroics.
Germán's 2023 perfecto proved the achievement remains possible, but modern baseball's structure makes each one more remarkable than the last.

What Are the Odds of Throwing a Perfect Game?
With 24 perfect games across 238,500+ MLB games, the mathematical odds stand at roughly 0.01% — or 1 in 10,000.
But probability alone doesn't capture the complexity. Every defensive play must be executed — a third baseman's throw, a first baseman's stretch, a diving catch with the baseball glove. No batter can reach via bunt single, walk, or error. Base running becomes irrelevant because no runner ever exists.
Perfect games require elite skill meeting fortunate circumstances: weak contact finding gloves, close calls going the pitcher's way, and zero defensive lapses across 27 outs.
Conclusion
A perfect game remains baseball's ultimate pitching achievement — just 24 in over 147 years of Major League history. Each one required a pitcher to silence batting lineups completely, earning a place alongside Baseball Hall of Fame legends.
Modern baseball's power-focused approach makes perfection harder, yet when skill and circumstance align, history still happens. Whether you're deepening your understanding of baseball terminology or following MLB action through live betting, the pursuit of the next perfect game keeps fans engaged with every pitch.
