John Libka (born June 13, 1987) is a Major League Baseball umpire.
Libka was born on June 13, 1987, in Saginaw, Michigan, to Gary and Lori Libka. [2] He grew up in Mayville, Michigan, and attended high school at the Juniata Christian School in Vassar, Michigan. Libka played baseball through his junior year in high school before beginning to umpire through the Michigan High School Athletic Association's Legacy Program. Under the direction of his father, Gary, Libka officiated his first games at age 16. After high school, Libka attended Pensacola Christian College, graduating with a degree in education. After a teaching internship, Libka decided to return to umpiring, attending the Wendelstedt Umpire School and graduating in 2010. [3] Libka now is an instructor at the Wendelstedt School. [4]
Libka made his Major League Baseball debut on May 27, 2017, umpiring a doubleheader in which the Detroit Tigers visited the Chicago White Sox. [5] On July 6, 2017, he ejected his first player, sending the Houston Astros' Marwin González off the field for arguing balls and strikes. [6] Through the 2018 regular season he was found to be the best performing home plate umpire in terms of accuracy in calling balls and strikes, with an error rate of 7.59 percent, and second best in 2018 alone, with an error rate of 7.33 percent. This was based on a study conducted at Boston University where 372,442 pitches were analyzed. [7] Through the end of the 2021 season, Libka was used in the majors as a substitute, also knows as a "callup" umpire. He was officially hired by MLB starting with the 2022 season. [8]
In baseball, the umpire is the person charged with officiating the game, including beginning and ending the game, enforcing the rules of the game and the grounds, making judgment calls on plays, and handling the disciplinary actions. The term is often shortened to the colloquial form ump. They are also sometimes addressed as blue at lower levels due to the common color of the uniform worn by umpires. In professional baseball, the term blue is seldom used by players or managers, who instead call the umpire by name. Although games were often officiated by a sole umpire in the formative years of the sport, since the turn of the 20th century, officiating has been commonly divided among several umpires, who form the umpiring crew. The position is analogous to that of a referee in many other sports.
