Terrance Joseph Cooney (born April 12, 1933 in Condon, Oregon) is a former umpire in Major League Baseball who worked in the American League from 1974 to 1992; he wore uniform number 12. He officiated in the 1981 World Series, three American League Championship Series (1978, 1986 and 1990) and two All-Star Games (1979, 1989).
Cooney attended Sacred Heart Academy in Salem, Oregon, where he earned 14 letters in sports including baseball, football and track, and then played four years of AAU and semi-pro baseball in the Northern California League. He studied physical education and police science at Willamette University, the Oregon College of Education and Modesto Junior College, and also served in the United States Marine Corps. After attending the Umpire Specialization Course, he began his career in the California League (1969–70), Texas League (1970) and Pacific Coast League (1971–74) before moving up to the AL staff at the end of the 1974 season. He was a resident of Fresno, California throughout his major league career until relocating to suburban Clovis prior to the 1991 season.
Cooney was the home plate umpire in Game 4 of the 1990 American League Championship Series where he ejected Boston Red Sox pitcher Roger Clemens with two out in the bottom of the second inning after Clemens used profanity while arguing balls and strikes. The Red Sox were trailing the Oakland Athletics 1-0 and eventually lost 3-1, being swept in four games.
Cooney was a prison guard in the 1960s and was encouraged by an inmate to go to umpire school. The inmate had seen an ad during a Game of the Week telecast promoting professional umpire school in Florida. Cooney successfully made it through the school and worked his way to the majors for the end of the 1974 campaign. Cooney was an American League umpire until an errant pitch from Frank Tanana hit him on the knee and effectively ended his career as an umpire in September 19, 1992. Cooney wore uniform number 12 in his A.L. career.
