Major League Debut of Umpire Alex Tosi (66)

Umpire Alex Tosi made his MLB debut during Saturday's Tigers-Twins doubleheader in Minnesota, serving as 1B Umpire alongside HP Umpire Hunter Wendelstedt, 2B Umpire Jordan Baker, and 3B Umpire Nauert for Game 1, and as 3B Umpire alongside HP Umpire Chad Whitson, 1B Umpire Baker, and 2B Umpire Nauert for Game 2.

Tosi is a crew chief on the 2019 International League umpire roster, which is his fourth year in Triple-A. Tosi has officiated the New-York Penn (2011), Midwest (2012), Florida State (2013), Arizona Instructional (2014), and Eastern (2014-15) Leagues in addition to the International League (2016-present).

He officiated the 2018 Triple-A National Championship Game, 2017 International League Postseason, and his multiple MLB Spring Trainings.

Tosi wears the sleeve number 66, which was last worn at the Major League level by Jim Joyce, who retired following the 2016 MLB season and was our featured guest on Episode 12 of The Plate Meeting podcast.

Tosi is the third rookie fill-in umpire to make his MLB debut during the 2019 regular season.
