Brian O'Nora has been a major league umpire since 1992.
O'Nora started off in the 1985 Appalachian League after attending the Joe Brinkman umpire school, then moved up to the Midwest League (1986-1987), Eastern League (1988-1989), Pacific Coast League (1990) and American Association (1991). In 1990-1992, he also worked the Puerto Rican Winter League. From 1992-1993, Brian was an umpire in the International League, but also worked games in the American League each year. He became a full member of the major league staff in 1994. He worked the 2000 All-Star Game. He also worked the 2008 ALCS and 2010 All-Star Game. He worked his first World Series in 2012.
O'Nora was part of the umpiring crew that was disciplined for an egregious misinterpretation of the rules on May 9, 2013, when they allowed Houston Astros manager Bo Porter to make an illegal substitution of a relief pitcher, over the protest of rival manager Mike Scioscia of the Los Angeles Angels of Anaheim. Crew chief Fieldin Culbreth bore the brunt of the Commissioner's office's wrath, being issued a two-day suspension in addition to the fine, but the other three members of the crew were fined as well for failing to correct the mistake.
