The Brewers’ Rotation Options After Peralta Trade

The Brewers traded ace Freddy Peralta and swingman Tobias Myers to the Mets last week. Milwaukee generally, though not always, trades its best players as they approach their final year before free agency. There was never much chance they were going to meet Peralta’s asking price on another contract. That left the front office to decide whether to move him for controllable pieces or hold him through his final arbitration year and collect a compensatory draft pick when he signed elsewhere.

They opted for the former once the Mets put Jett Williams and Brandon Sproat on the table, albeit in a deal that also cost them a potential rotation arm in Myers. It’s obviously not the start of a rebuild for a team that had MLB’s best record and advanced to the NL Championship Series a year ago. They’re counting on their pitching pipeline to continue to produce as they aim for a fourth straight division title.

How will Pat Murphy’s starting staff line up?

Locks

Brandon Woodruff

Woodruff is back as the veteran anchor and their clear #1 starter. The righty accepted a $21.05MM qualifying offer, a move that probably surprised Milwaukee’s front office to an extent. President of baseball operations Matt Arnold acknowledged that getting Woodruff back made them more comfortable parting with Peralta (relayed by Curt Hogg of The Milwaukee Journal-Sentinel). The 2026 payroll factors into that to an extent, yet Peralta’s $8MM salary shouldn’t have been a hang-up even by Brewers’ standards. There were other players they could have moved (e.g. Andrew Vaughn, Trevor Megill) if ownership mandated a payroll reduction.

The Brewers can feel comfortable about having an established top-of-the-rotation starter. The big question is how many innings they can reasonably expect. Woodruff missed all of 2024 rehabbing from shoulder surgery. A handful of smaller injuries delayed his ’25 debut, and he sustained a season-ending lat strain after 12 starts. He has pitched 131 2/3 frames over the past three seasons. Woodruff enters camp fully healthy, but it’s fair to wonder if he can shoulder 150 innings.

Quinn Priester

The 25-year-old Priester is now the second-most experienced Milwaukee starter. He and Robert Gasser are the only other starters with more than a year of MLB service time; the majority of Gasser’s service came on the injured list working back from UCL surgery.

Priester began the ’25 season in Triple-A with the Red Sox. Dealt to Milwaukee in a rare April trade of significance, the former first-rounder was a revelation. He tossed 157 1/3 innings of 3.32 ERA ball behind a massive 56.1% grounder percentage. Milwaukee had a stretch of 19 consecutive wins in his outings between May and September. Priester has serviceable but not elite swing-and-miss stuff. It’s a sinker-slider profile geared toward keeping the ball on the ground. That approach comes with some batted ball variability but plays well in front of a strong infield defense.

Upside Plays

Jacob Misiorowski

Misiorowski was arguably the #1 pitching prospect in MLB when the Brewers called him up in June. He began his career in electric fashion, allowing two earned runs or fewer in six of his first seven starts. Milwaukee didn’t let him work deep into games, but he lit up the radar gun while missing plenty of bats. His performance wavered down the stretch, and evaluators’ longstanding concerns about his command pushed him into a bullpen role for the playoffs. Misiorowski impressed again in October, striking out 16 over 12 innings of three-run ball in a trio of postseason outings.

Overall, the 6’7″ righty finished his debut campaign with a 4.36 ERA across 66 innings. He’s certainly not going to be the back-end innings eater usually associated with a mid-4.00s ERA, though. Misiorowski has ace stuff with walk issues that may yet land him in high-leverage relief. He should get a full look in the rotation this year, albeit with questions about his start-to-start efficiency.

Logan Henderson

Henderson may not be a Misiorowski-level prospect, yet his 2025 debut was also highly anticipated by Milwaukee fans. He was called up in April and pitched well over four starts before being squeezed off the MLB roster. The Brewers brought him back up after the trade deadline. He made one start before being diagnosed with elbow inflammation and spending the rest of the season on the injured list. The 23-year-old righty allowed five runs while striking out a third of opponents over his first 25 1/3 MLB innings.

Baseball America ranked Henderson 96th on their Top 100 prospects list last week. They credit him with plus control and a plus changeup, while his 93 MPH fastball plays above its velocity because of his release angle and spin. Henderson has always been effective in the minors, posting a 3.26 ERA with a 32% strikeout rate over his career. Can he continue to miss bats at a high rate against MLB hitters without really trusting his cutter or slider? He might also run into some home run trouble as a fly-ball pitcher with average velocity whose fastball works best at the top of the strike zone. There are questions about the ultimate ceiling, but Henderson’s first five starts couldn’t have gone much better.

Brandon Sproat

Sproat will try to immediately replace Peralta in the starting five. He also landed in the back quarter of the aforementioned BA prospect list — a few spots above Henderson, in fact. Sproat has much bigger stuff, sitting 96-97 with above-average to plus grades on his slider, curveball and changeup. His command isn’t nearly as polished. Sproat walked 10.4% of opponents over 26 Triple-A appearances last year, and he was hit around a little bit over four starts as a September call-up. The 6’3″ righty has a shot to be a mid-rotation starter, but the command will need to improve if he’s going to get there.

Back-End Arms

Chad Patrick

Patrick was a 26-year-old rookie whom the Brewers acquired from the A’s in 2023 for journeyman infielder Abraham Toro. There wasn’t a whole lot of fanfare when he broke camp for his MLB debut last spring. Patrick went on to a seventh-place finish in Rookie of the Year balloting after tossing 119 2/3 innings of 3.53 ERA ball. There’s a decent chance he would have placed more highly had the team’s rotation depth not pushed him to Triple-A when Woodruff returned to action on July 6.

The righty spent six weeks in the minors through no real fault of his own. He worked in a swing role once he was recalled in the middle of August. Patrick pitched well in either role and had an excellent postseason, firing nine innings of two-run ball with 11 strikeouts. He has a six-pitch mix led by a plus cutter that helped him punch out a quarter of opponents. Patrick probably doesn’t have the ceiling of some of his teammates but should enter camp with a leg up on Henderson and Sproat for the fourth or fifth starter role.

Robert Gasser

Acquired from San Diego in the Josh Hader trade, Gasser had an impressive five-start debut in 2024. He blew out and underwent elbow surgery that kept him off an MLB mound until last September. The southpaw started two games and gave up six runs (only two earned) with four walks and five strikeouts across 5 2/3 frames. His minor league rehab numbers were quite a bit better. The 26-year-old Gasser has a 3.72 ERA with a 28% strikeout rate in just over 200 career Triple-A frames. He’s on the older side for a prospect because of the injury but still looks like a viable back-end starter.

Likely Relievers

Angel Zerpa, Aaron Ashby and DL Hall each have starting experience but fit better in the bullpen. All three were used primarily as relievers last season — with the Royals, in Zerpa’s case — and join Jared Koenig in giving Milwaukee a quartet of big arms from the left side out of the bullpen.

Zerpa has solid command and gets a ton of ground-balls, but his sinker/slider combination leaves him vulnerable to right-handed hitters. He’d probably need to pick up a splitter or cutter if he’s going to turn over a righty-heavy lineup twice in a game. Ashby hasn’t managed to stay healthy as a starter, while Hall’s command is too big an obstacle. They’re all capable of working multiple innings and could get some action as openers, as Ashby did a few times in the postseason to match him up against Kyle Tucker and Shohei Ohtani.

The other two starters on the 40-man roster, Carlos Rodriguez and Coleman Crow, project as up-and-down arms. Rodriguez has decent stuff but has been walk-prone in the minors. He has allowed 18 runs in 22 career big league innings. Milwaukee added Crow to the roster at the beginning of the offseason to keep him out of minor league free agency. He’s the organization’s #30 prospect at Baseball America and has fringy stuff despite impressive strikeout rates in the minors.

——————————–

Even without Peralta, Milwaukee has a talented group of starters. Their collective lack of experience behind Woodruff means they’ll probably add a fifth starter or swingman on a one-year deal to reduce the load on their young arms. As is always the case for the Brewers, they’re likely to mix in some tandem starts/openers while shuffling pitchers up and down from Triple-A. Woodruff is their only starter who can’t be sent to the minor leagues, while Rob Zastryzny is their only out-of-options reliever. They’ll have a lot of roster flexibility if they want to incorporate bullpen games or a six-man rotation to keep pitchers’ innings in check.
