The moment the Milwaukee Brewers signed Cooper Pratt to a $50 million contract extension, it seemed only a matter of time before he reached the major leagues. That long-awaited opportunity has now arrived, with Adam McCalvy of MLB.com reporting that the Brewers are calling up Pratt for his MLB debut.
Rumors of his promotion began circulating after Pratt was removed from a game with Triple-A Nashville. Shortly afterward, Patrick Kinas shared a video showing the highly regarded prospect embracing his teammates in the dugout. McCalvy then confirmed the news minutes later.
Because Pratt was added to Milwaukee’s 40-man roster when he signed his extension, the Brewers only need to make a corresponding active roster move to officially place him in the lineup.
The 21-year-old is expected to make his major league debut on June 16 when Milwaukee takes on the Cleveland Guardians.
Brewers Promote Cooper Pratt
At the time of his promotion, Luke Adams Pratt was ranked as the No. 4 prospect in the Milwaukee Brewers organization and the No. 90 overall prospect in baseball. Selected in the sixth round of the 2023 MLB Draft, the young infielder has wasted little time making his way through the Brewers’ farm system, steadily rising through the ranks thanks to his strong development and consistent performance.
Milwaukee has high expectations for Pratt, choosing to work out an extension well before his debut. The deal runs through the 2033 season, plus club options for 2034 and 2035. So that means that Pratt could be the Brewers’ starting shortstop for the next decade.
With Triple-A Nashville, the 21-year-old is slashing .244/.353/.392 with six home runs, 17 stolen bases, and a 102 wRC+. The offense doesn’t necessarily jump off the page, but most players of Pratt’s age aren’t playing in Triple-A. One thing to note is he has excellent strikeout (14.3%) and walk (13.2%) rates at the minor league’s highest level.
Pratt is also a strong defender, winning the Minor League Gold Glove at shortstop last season. He should help the Brewers stay strong defensively at the position, even with a lineup change imminent.
How Cooper Pratt’s Promotion Affects Brewers Infield
Cooper Pratt assumes the everyday shortstop role for the Brewers. The Brewers entered play on June 14 with the fourth-best wRC+ in MLB at 107. So there shouldn’t be too much pressure on Pratt to perform right away.
That displaces Joey Ortiz from the lineup, with the more intriguing question of what happens next for the 27-year-old.
Ortiz was one of two players the Brewers received in the Corbin Burnes trade, along with DL Hall. After a promising rookie season, Ortiz’s offense has backed up. Since the start of the 2026 season, Ortiz has been hitting just .224 with a .586 OPS.
While he has graded well defensively at shortstop, at +19 Outs Above Average since moving to the position full-time. However, with the Brewers having championship aspirations, they cannot afford to keep playing such a light bat.
Milwaukee will have to decide who to proceed with as the utility infielder off the bench. Ortiz has defensive versatility, playing at both shortstop and third base as a regular. He’s graded out well at both positions defensively.
The same can’t be said for the veteran Luis Rengifo. Rengifo signed a $3.5 million deal in the offseason to be their primary infielder off the bench.
However, he’s only slashing .204/.281/.254 at the plate as the shorter half of the third base platoon. The Brewers would have to designate the 29-year-old for assignment if they keep Ortiz over him. That roster move will likely be announced on June 16.
