Nestor George Chylak Jr. (; May 11, 1922February 17, 1982) was an American umpire in Major League Baseball who worked in the American League from 1954 to 1978. He umpired in three ALCS (1969, 1972, 1973), serving as crew chief in 1969 and 1973. He also called five World Series (1957, 1960, 1966, 1971, 1977), serving as the crew chief in 1971 (in which he worked home plate in the decisive Game 7) and 1977. He also worked in six All-Star Games: 1957, 1960 (both games), 1964, 1973 and 1978, working home plate in the second 1960 game and in 1973. Early life Chylak was born in Olyphant, Pennsylvania. His parents, Nestor Sr. and Nellie, were of Ukrainian descent; Chylak was the first of their five children. He attended the University of Scranton, where he studied engineering. During World War II, he served in the U.S. Army in Europe. He suffered shrapnel injuries in Battle of the Bulge, which blinded him for several days and hospitalized him for eight weeks. He earned both the Silver Star and Purple Heart during his service. After the war, he began umpiring amateur baseball in 1946, and returned briefly to college. Career After a year in amateur baseball, Chylak moved into the minor leagues as a Pennsylvania-Ontario-New York League umpire. He spent several more minor league seasons in the Canadian–American League, the New England League, and the Eastern League. He debuted in the major leagues in 1954. Chylak said that two of his greatest thrills occurred in the early to mid-1960s. In the 1960 World Series, he was umpiring when Bill Mazeroski of the Pittsburgh Pirates hit the home run that allowed the Pirates to defeat the New York Yankees. He worked Sandy Koufax's final game in the 1966 World Series in which Koufax and the Dodgers faced the Baltimore Orioles and Jim Palmer. Chylak worked the first American League Championship Series in 1969. On June 4, 1974, he was on the field in Cleveland for "Ten Cent Beer Night". The Cleveland Indians had been struggling with low attendance figures, resulting in this promotion that attracted more than 25,000 fans to the game. Fans became unruly and incited fights with the players, sometimes pouring beer on them. Chylak declared the game a forfeit after he sustained a facial wound from being hit with a chair. He was the home plate umpire for the first
