John Francis Paciorek is currently a Physical Education teacher at a small private school in San Gabriel, California. His greatest claim to fame is that he is the subject of a trivia question whose answer denotes that he is the sole possessor of the highest lifetime Batting average, Slugging percentage, and On-base percentage, in all of Major League Baseball’s illustrious history.
He is famous for having arguably the greatest one-game career in baseball history. Paciorek, who had been called up when rosters expanded in September, got into the final game of the 1963 season, on September 29 as the right fielder. Besides making 3 running catches on defense, he came to the plate five times. He hit three singles and drew two walks, for a perfect career batting average and on base average of 1.000. As if that wasn’t enough, he also scored four runs and had three RBIs during the game.
A Back injury forced Paciorek to have surgery early in 1964, causing him to miss that entire season as well as all of 1965. He tried to recover while playing in the minors until 1969 but was never quite the same player, and never again played in the big leagues.
In the past 50 years since his “Big League” debut, he has devoted himself to understanding the Principle(s) through which the most efficient means to applying the proper mechanics for hitting and throwing a baseball can be taught and implemented.
John is the author of two books, Plato & Socrates, Baseballs Wisest Fans and The Principle of Baseball, and All There is to Know About Hitting.
