Addison Barger, an exciting young talent, is an American professional baseball third baseman and outfielder who made his Major League Baseball (MLB) debut with the Toronto Blue Jays in 2024. Drafted by the Blue Jays in 2018, Barger quickly ascended through the minor league ranks, notably having a breakout 2022 season where he hit .308 with 26 home runs and 91 RBI across three levels. After being added to the Blue Jays' 40-man roster in November 2022, he earned his first MLB call-up on April 24, 2024, collecting his first major league hit shortly after and hitting his first MLB home run on July 29, 2024.

Barger's career reached an incredible high point on October 24, 2025, when he hit his first career grand slam in Game 1 of the World Series, making history as the first pinch-hitter ever to achieve this feat in the Fall Classic. This historic grand slam, despite a .197 batting average in his rookie campaign, firmly established Barger as a player with significant potential for the Toronto Blue Jays.
