He made his major league umpiring debut on August 2, 2010. He umpired in six major league games in 2010, and returned in 2011, umpiring in 68 games.[2] On July 1, 2016, Tumpane was promoted to the full-time MLB umpiring staff.[3]
Tumpane is known for his emphatic and demonstrative strikeout signal in which he hammers his right fist in the direction of the right-hand batter's box in a similar fashion to stabbing, which has earned him the nickname "The Ripper".[4]
In game 2 of the 2020 American League Championship Series, on October 12, 2020, Tumpane correctly called 134 of 135 pitches at which a batter did not swing.[8]
On September 27, 2022, Tumpane, serving as first base umpire, called an MLB-record 3 balks on Miami Marlins pitcher Richard Bleier while Bleier was pitching to the same batter in a single at bat. Bleier had never been called for a balk in his MLB career previously, over the course of 303 games in seven seasons.[9] It was the only time since at least 1900 that one pitcher was called for a balk three times in a single plate appearance.[10]
