Cooper Pratt Makes MLB Debut for Brewers, Records First Double Play Against Guardians

Cooper Pratt, the Milwaukee Brewers' top-four prospect, made his Major League Baseball debut as the team's starting shortstop and turned a double play in the second inning during a 2-1 victory over the Cleveland Guardians. The 21-year-old shortstop was promoted from Triple-A Nashville after signing an eight-year contract with the organization in April.

From Nashville to Milwaukee

Pratt had been waiting months for his call to the majors following the signing of his long-term deal. Rather than easing pressure, the contract initially intensified it. Early in his Triple-A season, he struggled, questioning the decision. His approach shifted when he focused on the process of winning at-bats rather than chasing statistics, leading to steady improvement with Nashville.

Manager Rick Sweet signaled to Pratt during a sixth-inning moment in Nashville—a moment Pratt described as "magical." He flew out the next day and arrived in Milwaukee. The speed of the transition from high school, which was only three years prior, remained surreal to the young prospect.

Debut Performance and Team Victory

In his first Major League game, Pratt grounded out in all three at-bats and committed a throwing error while also missing a hit-and-run sign. However, these rookie mistakes were overshadowed by the team's success. Brice Turang and Garrett Mitchell each hit solo home runs, while starter Robert Gasser pitched into the sixth inning without allowing a run. Reliever Aaron Ashby became the first pitcher in the majors to reach double-digit wins.

Pratt's most memorable moment came in the second inning when he and Turang completed the 6-4-3 double play—the defensive gem now preserved in an authenticated baseball case at his locker labeled "FIRST MAJOR LEAGUE DOUBLE PLAY." The Brewers clubhouse staff ensured the moment would be remembered despite the absence of a first hit or RBI. Turang kept the atmosphere light for the debut, reminding Pratt that baseball is ultimately a game meant to be enjoyed.

Roster Adjustment

To make room for Pratt on the roster, the Brewers designated infielder Luis Rengifo for assignment. Rengifo, who signed a one-year deal worth $3.5 million in the offseason, has struggled significantly in 2025. Through 209 plate appearances as a Brewer, he compiled a .205 batting average with a 53 weighted runs created plus (wRC+). His performance prompted the club to move forward with the young shortstop prospect instead.
