John Kenneth (Johnny) Miljus (Serbian Cyrillic Џон Кенет Миљуш or Serbian Latin Džon Kenet Miljuš) (June 30, 1895 – February 11, 1976) nicknamed "Big Serb" and "Jovo", was a Serbian-American baseball player who pitched in Major League Baseball between 1915 and 1929.

[1] Miljus served in the United States Army during World War I, in France, as part of the 320th Infantry.

[2] More than a dependable pitcher, he filled several roles coming out from the bullpen as a closer or a middle reliever, and as an occasional starter as well.

Miljus is probably best remembered as the pitcher who served up a ninth-inning wild pitch that escaped Pirates' catcher Johnny Gooch and allowed the New York Yankees to sweep the 1927 World Series.

[3] In a seven-season career, Miljus posted a 29–26 record with 166 strikeouts and a 3.92 ERA in 457+1⁄3 innings pitched, including 45 starts, 15 complete games, two shutouts, and five saves.
