Brewers Prospect Weekly: Boeve's Walk Rate Goes Parabolic, Thompson Deals at Biloxi
By Mason Grant ·
Brewers Prospect Weekly covers the last 7 days of action for the Brewers farm system.
Boeve's Patience at Double-A Is Becoming the Story
Mike Boeve (AA, OF, Rank: 44) went 4-for-12 with a double, three walks, and a strikeout across 12 plate appearances at Biloxi this week. The raw counting line is modest, but the context around it is not. Over his last 30 days, Boeve is slashing .301/.440/.397 with an 19.8 percent walk rate and a 18.7 percent strikeout rate across 91 plate appearances, and his swing rate has dipped to 38 percent, which is genuinely selective for this level. On the season at Double-A, that translates to a 12.7 percent walk rate and a contact rate of 78.6 percent, both of which represent real improvements over a 2025 campaign at the same level where he slashed .233/.329/.336 in 301 plate appearances.
The scouting profile on Boeve is a contact bat with a 50 hit tool, 40 power, and a second-division regular ceiling at third base. None of that has changed. What has changed is the evidence that the approach is genuine and repeatable. His power output remains a question, one homer over the last 30 days against a .397 slugging percentage, but the gap-oriented contact has held up and the zone management is the best it has looked across his time in the system. A 24-year-old outfielder without loud tools has a narrow path to a big-league role, and he does not make that path any wider by going passive. But a 19.8 percent walk rate that coexists with a contact rate north of 78 percent over a meaningful sample is worth tracking. The bat is doing what the profile needs it to do, even if the power volume has not followed.
Thompson's Best Biloxi Outing Comes at the Right Time
J.D. Thompson (AA, LHP, Rank: 36) tossed five innings of one-run ball this week, allowing just two hits and two walks while striking out four and generating nine swinging misses on 85 pitches. For a pitcher whose Double-A walk rate sits at 15.8 percent on the season, the two-walk afternoon was the headline. The 55-grade four-seamer, sitting 93-96, plays above its velocity out of a low left-handed release, and when the changeup and slider tunnel off that shape, the swing decisions get messy for right-handed hitters. The nine swinging misses against 19 batters faced reflect that at its best.
The full-season picture at Double-A is still rough enough to give pause: a 4.33 ERA across 27 innings with a 15.8 percent walk rate and four home runs. Over the last 30 days, though, the ERA sits at 3.24 with a 28.3 percent strikeout rate and a 33.2 percent whiff rate across five starts. The command is still the profile's central question, and a 45 command grade reflects that honestly. The starter projection at number four is built on the fastball's carry and deception rather than premium stuff, and the secondary mix is functional enough to support that if the walks come down. This outing showed what the upside looks like when the delivery stays on time: a lefty with a legitimate plus-playing fastball and enough secondary depth to get through a lineup twice. Whether he can do it consistently against Double-A lineups is a different conversation, but this was the reset the month needed.
Quick Hits
- Jesús Made (AA, SS, Rank: 1) · drove in three runs on four hits, including a solo homer, across 14 plate appearances this week. A switch-hitter with a 60 hit tool, 55 power grade, and 60 speed, he has 37 stolen bases on the season and 91 RBI in 558 plate appearances at Double-A. The 14.3 percent strikeout rate over the full season is one of the cleaner contact profiles in the system. Over his last 30 days, he is posting an 11.0 percent strikeout rate and 84 percent contact rate, two numbers that make the 60 hit tool look like a floor rather than a ceiling. Made turned 19 in June and is spending his age-19 season at Double-A; the profile's primary developmental target remains defensive reliability at shortstop.
- Josh Adamczewski (AA, OF, Rank: 5) · went 3-for-13 with two doubles, two walks, and a pair of strikeouts in 13 plate appearances this week. The week was measured, but the season context is not: he is slashing .300/.417/.509 with 18 home runs and 78 walks across 494 combined plate appearances at High-A and Double-A. The 19.4 percent walk rate over the last 30 days at Biloxi is consistent with a 15.8 percent mark on the combined season, and the 55 hit tool with average power is producing at a rate that has outpaced the projections for a 21-year-old. The defensive fit at second base or left field remains the primary ceiling question.
- Blake Burke (AAA, 1B, Rank: 8) · had a week to forget, going 1-for-18 with three walks and five strikeouts across 21 plate appearances at Nashville. It was a rough cap to a difficult Triple-A stretch: over the last 30 days, he is hitting .195 with a 29.8 percent strikeout rate and a 57.2 percent swing rate across 94 plate appearances. The 60 power grade made him an exciting bat in the system at Double-A, where he slugged .603 with 30 home runs in 431 plate appearances this season. At Triple-A, that same aggressive swing-and-miss profile is getting exposed, and the contact rate of 70.4 percent has not improved between levels. There is still real juice here; the everyday first base projection has not changed. But the adjustment to Nashville pitching has been slower than the Double-A numbers suggested it would be.
- Jeferson Quero (AAA, C, Rank: 9) · collected three hits and two RBI in 19 plate appearances this week, but zero walks and three strikeouts kept the week from amounting to much. The last-30-day picture at Nashville is more concerning: a .182 average, a 4.2 percent walk rate, and a 22.2 percent strikeout rate across 72 plate appearances, with the swing rate sitting at 54 percent. A 60 field grade and plus arm make him a legitimate catching prospect regardless of the bat, and his 2025 Triple-A numbers were considerably cleaner at a 10.0 percent walk rate and 14.0 percent strikeout rate in 250 plate appearances. The offensive regression from last season to this one is real, but the defensive profile keeps the everyday ceiling intact. September has not been kind.
- Braylon Payne (AA, OF, Rank: 3) · went 1-for-10 with a homer, three RBI, a walk, and five strikeouts in 15 plate appearances this week. The good news is that the homer was his sixth in 22 Double-A games this month. The harder number is the 30 strikeouts in 98 plate appearances over his last 30 days, which puts the strikeout rate at 30.6 percent at the level. A 70 speed grade and 55 field grade give him a clear everyday path in center field, and the 28 home runs on the combined season represent a genuine power step. But the 64.5 percent contact rate paired with a 59.3 percent swing rate over the last 30 days is a combination that will get punished more severely as he faces better sequencing. The tools are legitimate; the swing decisions remain the variable.
- Manuel Rodriguez (AA, RHP, Rank: 39) · worked 4.2 scoreless innings, scattering four hits and no walks while striking out five and generating 11 swinging misses in 65 pitches. The zero walks against 18 batters faced was the story: Rodriguez carries a 5.6 percent walk rate at Double-A on the season, one of the better command marks in the Biloxi rotation. The 2026 season has been a mixed bag, a 4.74 ERA driven by 31 home runs allowed in 133 innings, but when the fastball-slider-changeup combination is landing, the contact management can look like this. The projection as a long reliever or swingman is built on this kind of strike-throwing efficiency; the home run rate is the ceiling question.
