7. INF Luis Peña
Another Brewers prospect who has yet to make his MLB debut cracks the top 10, as 19-year-old Luis Peña claims the No. 7 spot on our list. Peña has showcased legitimate five-tool potential at every stop in the minor leagues so far, while also demonstrating defensive versatility by playing third base, shortstop, and second base. That positional flexibility only enhances his long-term profile, giving Milwaukee multiple paths to eventually fit him into the major league roster.
This season, Peña got off to a blazing start in High-A, recording 16 hits over his first 12 games, including three extra-base hits. His speed and aggressiveness on the bases were also on full display, as he swiped six bags during that stretch. Unfortunately, a dehydration-related medical scare that required a neurological consultation afterwards has sidelined him for the past several weeks. The good news for Milwaukee, however, is that Peña has since been cleared to resume baseball activities and should return to action in the near future.
6. LHP Kyle Harrison
In what already looks like another Matt Arnold masterclass in acquiring a high-upside starting pitcher with years of team control remaining (also from the Red Sox), Kyle Harrison has followed a similar path in that regard to the one Priester took the year before. What gives Harrison even more value, however, is that he is left-handed and possesses the swing-and-miss ability that Priester lacks, as evidenced by his impressive 11.7 strikeouts per nine innings so far this season.
With more overpowering stuff on the mound, Harrison’s ability to completely take over a game feels very different from Priester, who primarily succeeds by inducing weak contact and generating ground balls. Harrison’s electric arm gives the Brewers another potential frontline ace to pair alongside Jacob Misiorowski at the top of the rotation, exactly the kind of high-end pitching Milwaukee may need to finally take the next step in the postseason.
5. CL Abner Uribe
Speaking of high-end pitching, after struggling a bit with command and harnessing his emotions, Abner Uribe fully showcased his potential last season by putting together a dominant campaign that featured a 1.67 ERA across 75 appearances. That breakout year also included seven saves and an impressive postseason showing in which he handled a heavy workload and thrived in high-leverage situations.
While Uribe has had a few inconsistent outings this season, which have pushed his ERA up to 4.67, his stuff remains electric and among the most overpowering in the bullpen. If Milwaukee is going to make a deep postseason run, he’ll need to be at his best in high-leverage situations, especially given past instances where untimely home runs, such as those allowed during the Josh Hader and Devin Williams eras, have derailed playoff pushes for the Brewers. Even so, Uribe remains a key long-term piece, still in pre-arbitration through 2027 and not slated to reach free agency until 2031.
