What to expect from Brewers No. 4 prospect Pratt in The Show

When the Brewers signed Cooper Pratt to an eight-year, $50.75 million contract back in April, the organization said it wouldn’t accelerate the timeline for the 21-year-old shortstop’s arrival in the Major Leagues. But it did make clear that it saw him as a long-term piece of its future.

This week, the future will become the present.

Milwaukee is calling up its No. 4 prospect from Triple-A Nashville ahead of a home series against the Guardians set to begin Tuesday, MLB.com’s Adam McCalvy reported Sunday.

Ranked as the No. 63 overall prospect in the sport by MLB Pipeline, Pratt has hit .241/.349/.386 with six homers and 17 steals in 58 games with Triple-A Nashville leading up to his promotion. His 0.92 BB/K ratio ranks 15th-best among 181 qualifiers at the Minors’ top level, while his 14.2 percent places 17th. Taking his whole production into account, Pratt’s 100 wRC+ with the Sounds made him a plum average hitter for the International League after being the seventh-youngest player in the circuit on Opening Day.

It’s that ability to make consistent contact that the Brewers are likely betting will translate quickest offensively to the Majors with this week’s move. Pratt whiffed on only 17.3 percent of his swings with Nashville, ranking 14th among 151 Triple-A hitters (min. 250 PA), and he showed he can handle velocity well, batting .323 with a .548 slugging percentage and 9.8 percent whiff rate against pitches at or above 95 mph. (He faced 132 of them.)

The overall power is the bigger question in the box. Pratt maxed out with a 109.9 mph exit velocity on a single on May 9. His 35.8 percent hard-hit rate in Triple-A is equal to Christian Yelich’s in 2026 and would equate to the 25th percentile in the Majors without adjusting for the difference in qualities of pitching between the two levels. Standing 6-foot-4, the right-handed slugger has the frame to add more pop later in his 20s, but he’ll also have to improve his angles off the bat to get to average power; 50.6 percent of his batted balls were on the ground with Nashville.

That aside, Pratt’s shortstop defense remains his best tool as he heads to The Show. He won a Minor League Gold Glove Award at Single-A and High-A in 2024 and has continued to show strong instincts and timing at a premium position. Plus arm strength helps him complete plays deep in the hole, and he typically doesn’t trade power for accuracy on his throws either. He should be a defensive asset for the Crew right out of the gate.

Pratt can also flash above-average run times out of the box and has been impressively efficient on the basepaths in 2026, having only gotten caught once in his 18 steal attempts.

Entering Monday, the Brewers (43-26) own a five-game lead over the Cardinals in their pursuit of a fourth straight NL Central division title. But as good as the team has been overall, it has struggled to find consistent production from the left side of the infield. Milwaukee shortstops have the worst wRC+ in the Majors as a group (59) and rank 29th in collective fWAR (-0.2). Third basemen haven’t been much better with a 77 wRC+ and 0.3 fWAR.

There’s every chance Pratt could perform similarly to Joey Ortiz out of the gate at shortstop – low whiffs, low slugging percentage, high value with the glove – but given their differences in size (6-foot-4 vs. 5-foot-10) and age (21 vs. 27), the prospect has more upside long-term and could grow into a better power option by the time Milwaukee reaches the stretch run and, eventually, the postseason. Ortiz, on the other hand, could slide over to third where he was an exceptional defender in 2024, and Luis Rengifo, who’s yet to homer in 209 plate appearances, could move out of the infield rotation.

Back in 2023, the Brewers took Pratt in the sixth round out of the University of Mississippi and signed him for second-round money ($1.35 million) in what was seen as a possible steal at the time. They developed him into a Top 100 prospect over the three years since and are set to plug him into a Major League club that plans to keep on chugging right through to October. If that sounds like a familiar story, that’s because it has become one for an organization that boasts the best farm system in baseball.
