Does anyone have a 1.000 batting average?

The Only Perfect Batting Average in MLB History

When it comes to Major League Baseball records, few are as elusive—or as perfect—as a 1.000 batting average. While many players dream of consistently hitting the ball, only one has managed to retire with a flawless average over a career: John Paciorek.

It’s a rare feat, and Paciorek holds a unique place in baseball lore. Over his brief MLB stint, he went 3-for-3 in his only major league game, all singles, giving him a lifetime average of exactly 1.000. What makes this even more remarkable is that he had more than two at-bats—setting him apart from others who may have gone 1-for-1 or 2-for-2 but didn’t sustain it.

His story is one of baseball’s great curiosities. Drafted by the Houston Colt .45s (now the Astros), Paciorek’s lone game came on September 29, 1963. He didn’t just get a hit—he had a standout performance, even drawing a walk later in the game. But due to team decisions and minor league commitments, he never got called back up. Despite a strong minor league career, he never played another MLB game.

Beyond the stat sheet, the Paciorek name runs deep in baseball bloodlines. John’s brothers, Jim and Tom, both enjoyed long careers in the majors. Tom, in particular, became a well-known outfielder and later a popular broadcaster. The family’s connection to the game adds a human touch to John’s improbable perfect record.

While a 1.000 average may seem like a statistical fluke, it’s a lasting testament to how unpredictable and magical baseball can be. And in the record books, John Paciorek remains alone at the top—with perfection, however brief, forever on his side.
