The Brewers pitching machine: how a small-market team manufactures aces
A team with a bottom-third payroll has fielded one of baseball’s best pitching staffs for the better part of a decade, by taking arms nobody else wanted, and arms nobody else had unlocked. The numbers behind the turnarounds are dramatic enough to lay out pitch by pitch.
There is a building in Phoenix that other front offices would love to walk through, and almost none of them have. When Milwaukee renovated its Arizona spring complex in 2019, it turned the old major league clubhouse into a roughly $60 million pitching lab so guarded that no reporter has been allowed inside. The same year, Chris Hook was promoted from minor league pitching coordinator to the big league staff. What has happened since is one of the quiet structural stories in baseball.
The reputation breaks into two separate skills, and they are worth separating because they require different things. The first is reclamation: taking a pitcher who was actively bad somewhere else and making him good. The second is development: taking a pitcher who was already good, or who had loud raw stuff, and making him great. Milwaukee does both, consistently.
The economics force the strategy. A small-market club cannot buy a frontline starter in free agency, so the Brewers buy broken ones cheaply and repair them. Pitchers like Jordan Lyles, Drew Pomeranz, Gio Gonzalez, Frankie Montas, and Nick Mears have all passed through and come out better. The cleanest example is the template the whole model is built on.
Wade Miley, the template
Across 2016 and 2017, split between Seattle and Baltimore, Miley posted a combined 5.48 ERA and led all of baseball in walks in 2017. He was, by results, one of the worst rotation arms in the majors. He did not sign until spring training had started, on a minor league deal, and began the year in Double-A. Then the Brewers told him to shelve his four-seam fastball and make his barely-used cutter the primary pitch. The result was a different pitcher.

The honest footnote: Miley’s peripherals lagged his ERA (a FIP near 3.6, a SIERA closer to 4.7), because he wasn’t missing bats. The lab bet on contact management over strikeouts: he ran a top-ten ground-ball rate and one of the three lowest fly-ball exit velocities in baseball, and it held. From a Double-A flier to a postseason start on three days’ rest, in one season.
Quinn Priester, the model in 2025
If Miley is the template, Priester is proof the machine still runs. A first-round pick of the Pirates, he was crushed for a 7.74 ERA in 2023, traded to Boston, made one start, and was moved again, on his third organization by age 25. The Brewers acquired him in April 2025 and took criticism for the cost.

The supporting cast rhymes. Jhoulys Chacin led the NL with 35 starts and a 3.50 ERA in 2018. Gio Gonzalez posted a 2.13 ERA over five starts after a deadline pickup. The names rotate; the pattern does not.
Fixing the broken is half the reputation. The other half is harder: taking a pitcher who already has real ability and finding the version of him that wins awards. The two best examples are separated by five years, and together they show the lab working on the two things that make pitchers elite: the pitch, and the command.
Corbin Burnes: from the home-run record book to the Cy Young
Burnes in 2019 wasn’t a struggling reclamation. He was a top prospect having one of the strangest disaster seasons on record. His four-seam fastball traveled in a straight line and got hit a very long way: 11 home runs in his first four starts, an 8.82 ERA, and a home-run rate of 3.12 per nine, a number so far outside the normal range it reads like a typo. A grip change turned that four-seamer into a cutter with violent movement. What followed was historic.

Same arm, one new pitch. A worst-in-the-league season became a Cy Young.
Bars scaled to HR/9. The 2021 mark anchored the lowest FIP (1.63) in the divisional era by anyone but peak Pedro Martinez.
| Corbin Burnes | 2019 | 2021 | Shift |
|---|---|---|---|
| ERA | 8.82 | 2.43 | led MLB |
| FIP | 6.09 | 1.63 | −4.46 |
| HR / 9 | 3.12 | 0.38 | −88% |
| Strikeout rate | volatile | 35.6% | elite |
| K / BB | 3.50 | 6.88 | +97% |
| WHIP | 1.84 | 0.94 | −0.90 |
| Primary pitch | 4-seam | Cutter | – |
The home-run rate alone tells the whole arc: 3.12 per nine, down to 0.38. Same pitcher, same arm, one new pitch.
Jacob Misiorowski: command catches up to a 104 mph fastball
Where Burnes was a pitch-design project, “The Miz” is a command project. The raw material was never in doubt: a junior-college arm who threw harder than almost anyone alive, but couldn’t throw it where he wanted. He walked 5.4 per nine in the minors with the scouting label that writes itself: high ceiling, high risk, the arm that either figures out the zone or flames out in Triple-A. Then the walks fell off a cliff while nothing else did.

The profile scouts are trained to distrust, huge velocity paired with huge walks, stopped existing.
He cut his walk rate nearly in half year-over-year while still throwing the fastest pitch ever recorded by a starter (104.5 mph).
| Jacob Misiorowski | Minors ’23–24 | 2025 | 2026 |
|---|---|---|---|
| BB / 9 | 5.4 | 4.2 | 2.4 |
| K / BB | 2.29 | 2.81 | 5.68 |
| K / 9 | 12.3 | 11.9 | 13.7 |
| WHIP | 1.19 | 1.24 | 0.79 |
The reputation runs on starters, but the bullpen may be the cleaner proof. Relievers are cheaper and more volatile, and Milwaukee keeps turning a parade of them into high-leverage weapons. The mechanism is a conveyor belt: develop or reclaim an arm at the league minimum, ride him, trade him a year before free agency, then reload. The closer’s chair tells the story on its own.
The individual turnarounds rhyme: Megill saved 21 with a 2.72 ERA in 2024, then made the All-Star team in 2025. Abner Uribe washed out in 2024, then returned in 2025 to post a 1.67 ERA and 2.7 WAR, seventh among all relievers in baseball. Same engine, pointed at relievers, manufacturing All-Star arms on minimum salaries and replacing each one from within the moment he gets expensive.
None of this would be remarkable if Milwaukee spent like a contender. It does not. For six seasons running, the Brewers have carried one of the lowest payrolls in baseball while fielding one of its best pitching staffs, and the distance between those two facts is the entire reason the lab exists.
Payroll rank vs. team-ERA rank, by year
Both scaled 1 (best / highest spend) on the left to 30 on the right. The wider the gap, the more the lab is doing.
| Year | Payroll | Payroll rank | Team ERA | ERA rank |
|---|---|---|---|---|
| 2021 | $132M | 18th | 3.50 | 3rd |
| 2022 | $153M | 19th | 3.83 | 12th |
| 2023 | $152M | 20th | 3.71 | 1st |
| 2024 | $163M | 18th | 3.65 | 5th |
| 2025 | $144M | 22nd | 3.58 | 2nd |
| 2026 | $133M | 22nd | 3.44 | 4th |
The honest wrinkle a rigorous reader should want: ERA and FIP haven’t always agreed. In 2024 the Brewers ranked fifth in team ERA but their FIP sat far higher, near the bottom third, pointing to elite defense and sequencing doing real work behind the staff. That defense was no hand-wave: Brice Turang won the NL Platinum Glove, Sal Frelick a Gold Glove, and Milwaukee’s right fielders led baseball in Defensive Runs Saved. In 2025 the gap mostly closed. The lab develops pitchers (the case studies prove it), but Milwaukee’s run prevention is a pitching-and-defense system, and the balance shifts year to year.
The efficiency math is where it turns striking. A 2026 Boston University study named the Brewers the most efficient spend-to-win team in baseball from 2021 through 2025. In 2025 they won more regular-season games than the Dodgers while carrying roughly a quarter of the payroll.
2026 luxury-tax payroll · same field, very different bill
Brewers~$135M
Dodgers~$416MBy contract value, the Dodgers pay just three players (Ohtani, Betts, and Tucker), roughly what the entire Brewers roster costs. Manufacturing pitching is not a charming small-market sidebar for Milwaukee; it is the only mechanism by which a team spending a third of what its chief rival spends can stand on the same field, and win.
The common threads
Two of the biggest turnarounds, Burnes and Miley, ran through the same pitch: a cutter introduced to replace a four-seamer hitters were squaring up. The Brewers draft for it deliberately, targeting pitchers who spin the ball well, because spin is the raw material for shaping pitches like that. The other lever is command: the slower work of turning Misiorowski’s walks into strikes. Hook’s philosophy is to resist overhauling a new arrival: get to know the pitcher, learn how he absorbs information, then introduce changes in the right “dosage of the medicine.” It is the opposite of a one-size template, which is part of why it has been so hard to copy.
Priester arrived broken and became a frontline starter. Misiorowski arrived wild and became must-watch television. Somewhere in a windowless building in Phoenix, the next one is already taking his medicine.
