Shane Drohan might be the least well-known of the three players the Milwaukee Brewers acquired in Monday’s six-player swap with the Boston Red Sox, but that doesn’t mean he isn’t talented, nor is it an indication that he lacks a big league future. Fully healthy and with a more diverse arsenal than he possessed prior to undergoing shoulder surgery 24 months ago, Drohan arguably profiles less as a long shot and more as a diamond in the rough. As my colleague Davy Andrews put it when assessing the deal, “The Brewers get the chance to work their magic on two young pitchers,” with the other being Kyle Harrison.
A 27-year-old southpaw whom the Red Sox took in the fifth round of the 2020 draft out of Florida State University, Drohan is coming off a 2025 season that saw him log a 3.00 ERA, 3.11 FIP, and 34.5% strikeout rate over 54 innings, the bulk of which came at Triple-A Worcester. Health was once again an issue, though this time it wasn’t his shoulder: The Fort Lauderdale native was out of action from early May until mid-August due to forearm inflammation.
Drohan discussed his arsenal, including how it was impacted by having gone under the knife two years ago, when the Red Sox held their annual rookie development camp at Fenway Park in mid-January.
———
David Laurila: I’ve seen your scouting profile, but how do you view yourself as a pitcher? What makes you effective?
Shane Drohan: “I think the biggest reason I’m effective is that I mix a lot. I have a large arsenal, five pitches, that I’m essentially comfortable throwing in any count. I’ll even throw curveballs, changeups, and sliders on 3-0. That puts a lot of pressure on the hitters, knowing that they can’t cancel out any pitch. I also attack both lefties and righties with my entire arsenal. I don’t limit myself against one side or the other.” Read the rest of this entry »
Ben Lindbergh and Meg Rowley banter about new (and encouraging) details about MLB.TV registration, Justin Verlander returning to the Tigers, the rites of spring training, and the Rafael Devers trade in retrospect, before previewing the 2026 Milwaukee Brewers (20:50) with The Milwaukee Journal Sentinel’s Curt Hogg, and the 2026 Texas Rangers (1:08:28) with MLB.com’s Kennedi Landry.
Clearly, none of those people who argues that the day after Super Bowl Sunday should be national holiday is in charge of the Brewers or the Red Sox. Things got complicated very early this week, as Milwaukee and Boston announced a six-player trade on Monday morning.
The Brewers received infielder David Hamilton and left-handed pitchers Kyle Harrison and Shane Drohan. The Red Sox received infielders Caleb Durbin, Andruw Monasterio, and Anthony Seigler, along with Milwaukee’s competitive balance Round B draft pick. The headliner of the deal is Durbin, who will slot in as Boston’s everyday second or third baseman. When you factor in that Boston also traded for Willson Contreras, signed Isiah Kiner-Falefa, and claimed Tsung-Che Cheng off waivers, the Red Sox have now added more than an entire infield this offseason. Don’t worry; their infield situation is still plenty complicated. Harrison headlines the package going to Milwaukee. The Brewers get the chance to work their magic on two young pitchers, and they get to add to their collection of speedy, scrappy, undersized infielders.
It was an odd trade in some ways. All six players were on 40-man rosters already. The Red Sox got the comp pick (as of now, the 67th pick in the draft) even though they were also getting the biggest name, a player who will go straight from Milwaukee’s starting lineup into their own. The left-handed Hamilton has a few more tools than the right-handed Monasterio, but the two are at least comparable; it’s likely that the handedness of the two players affected Boston’s willingness to part with him. You could argue that the Brewers gave up more than the Red Sox, but that they needed what they got much more. The Red Sox have one of the deepest rotations in the league, so Harrison is going from a team that would have struggled to find room for him to a team that will likely need him to hold down a rotation spot from day one.

Last night, the Brewers and Mets swung a big trade. Milwaukee sent staff ace Freddy Peralta, along with righty Tobias Myers, to Queens in exchange for two Top 100 prospects in Brandon Sproat and Jett Williams. Both are near-ready contributors who grade out as 50 FVs and slot into Milwaukee’s farm system as the club’s third- and fourth-best prospects, respectively. Sproat projects as a mid-rotation starter, while Williams is a middle-of-the-diamond player with an as-yet undetermined defensive home. Davy Andrews wrote up New York’s side of the swap. Here, we’ll take a look at the youngsters heading to the Midwest.
Let’s start with Sproat. After selecting the righty in the third round in 2022 and then failing to sign him, the Mets went back to the well a round earlier the following season. This time they got their man, and the former Florida Gator took to pro ball quickly. He posted a 3.40 ERA with 131 strikeouts in 116.1 innings in 2024, with solid walk and contact-management metrics alongside. He capped the year with seven starts at Triple-A, and while those were mostly forgettable, he entered 2025 as the club’s top farmhand and one of the brightest pitching prospects in baseball.
He then battled through an uneven 2025 campaign. He started slowly, with a new, less deceptive motion, and missed significantly fewer bats in the first half of the season than he had the year prior. Still, the traits that long made Sproat an enticing prospect mostly endured, as he was still sitting in the mid-to-upper 90s and mixing in a plus breaking ball. He righted the ship in July and saved some of his best baseball for the latter part of August, a run of form that culminated in his first big league call-up. Read the rest of this entry »
This one may be a little too one the nose. On Wednesday evening, the Brewers and Mets agreed to a trade that sent Freddy Peralta and Tobias Myers to the Mets in exchange for two top 100 prospects, Jett Williams and Brandon Sproat. That’s right, the Brewers got cheaper and younger by selling their best pitcher for prospects, the Mets flexed their financial muscle, and president of baseball operations David Stearns acquired Freddy Peralta. Welcome to every single day.
Peralta may not be your idea of a surefire ace, but he was the unquestioned leader of the Brewers rotation, their Game 1 starter in the playoffs for each of the past two years. As salary dumps go, this one is particularly depressing. Peralta is due just $8 million in his walk year, a hair more than the Angels will be paying Anthony Rendon to clear out of Anaheim as soon as possible, if you please. For Myers and the wildly underpaid Peralta, the Mets surrendered the prospects who ranked 31st and 63rd overall in our Top 100 update back in July. The Brewers did what they do, avoiding expenditures of any kind, finding young players, and trusting that they can keep creating aces out of whole cloth. Meanwhile, the Mets have increased their CBT tax hit from preposterously large to ludicrously large in order to reinforce a rotation that still ranks just 15th on our Depth Charts.
Brendan Gawlowski wrote about Sproat and Williams in a separate article, so our focus here is on the major league side of things, and we’ll start with the headliner. In February 2020, right before the world started exploding, Peralta signed a five-year, $15.5 million extension with two club options that could push the total to $30 million. He was, at that point, a 23-year-old with a career 4.79 ERA and 3.96 FIP and more relief appearances than starts. “We are happy to announce that we have reached a multi-year extension with Freddy that can keep him in a Brewers uniform for the better part of this decade,” said Stearns, then Milwaukee’s president of baseball operations. That prediction came true by the slimmest of margins.
Peralta pitched in relief in 2020, running a 3.99 ERA and an encouraging 2.41 FIP. He broke out in 2021. Over the past five seasons, Peralta has put up 14.8 WAR and gone 54-34 with a 3.30 ERA and 3.65 FIP. Despite dealing with shoulder injuries earlier in his career, he’s pitched at least 165 innings in each of the last three seasons. He anchored the rotation in 2024 when Corbin Burnes got traded and Brandon Woodruff got hurt. By my count, the Brewers extracted roughly two-thirds of a win for each million they paid Peralta. At that rate for their entire roster, the Dodgers would expect to win 208 games this season.
Peralta’s $8 million salary was the fourth-highest on the Brewers, but it will now slot in as the 14th-highest on the Mets. The galling part isn’t just that the Brewers couldn’t swallow the $8 million this year. Trading him means there wasn’t even a thought that they might be able to extend him, or at least that they might be able use a really good pitcher in 2026 and then just deal with losing him in 2027. After all, this is a team that just finished with the best record in baseball and made it to the NLCS. No matter. Milwaukee is taking the cash and the prospects and betting that Woodruff will finally get healthy (and that his alarming drop in velocity isn’t a portent of bad things to come).
After this year (and just in time for a possible work stoppage), Peralta will be entering his age-31 season and finally have the chance to make what he is worth on the open market, unless the Mets lock him up to another extension. This certainly seems like the kind of trade that ends up that way, especially when you consider that Stearns must like Peralta an awful lot, given that he has now traded for him twice and extended him once. Peralta won’t turn 30 until early June, and he just put up the highest fastball velocity of his career. Sproat was our top-ranked prospect on Eric Longenhagen’s updated Mets list from last June, and Williams came in at sixth. In his piece on the Brewers’ return, Brendan wrote that both players “are near-ready, 50-FV contributors and slot into Milwaukee’s farm system as the club’s third- and fourth-best prospects, respectively. Sproat projects as a mid-rotation starter, while Williams is a middle-of-the-diamond player with an as-yet undetermined defensive home.” That’s a serious haul. Keeping Peralta for a while would certainly take some of the sting out of losing them.
Peralta throws a four-pitch mix: four-seamer, changeup, curveball, and slider. He leads with the four-seamer, throwing it just over half the time to both righties and lefties. As Lance Brozdowski noted in his write-up of the trade, it’s a weird pitch (complimentary). It comes from a low release point not because of a low arm angle, but because he’s only six feet tall and he has a huge stride that brings him a long way down the mound. That huge stride also means huge extension. So even though Peralta’s 94.8 mph velocity put him in just the 57th percentile (among pitchers who threw at least 100 four-seamers in 2025), his 95.2 mph perceived velocity put him in the 74th percentile. A flat fastball with above-average velocity is a great combination, but it’s worth noting that Peralta really needs every bit of his stuff.
He hit the strike zone just 45% of the time in 2025, the lowest rate among all qualified pitchers. He ran the third-lowest mark in 2024 and the 13th lowest in 2023. Over the past five years, among pitchers who have thrown at least 2,000 pitches, his 46% zone rate puts him in the ninth percentile. That’s great if you can get away with it, as pitches over the plate are the ones that get hit. Peralta gives up too many walks, but he runs average chase rates and superlative whiff rates, allowing him to offset all those walks with tons of strikeouts and lots of weak contact. It’s a cocktail that some advanced ERA estimators, like DRA, absolutely abhor, but he’s got a long track record of success with it.
If and when Peralta’s stuff stops fooling batters, though, this trick could fall apart in a hurry. If he can’t induce chases, he’ll have to come into the zone. Once he’s in the zone, he’s probably going to allow more hard contact, and if he’s not inducing chases, he’s probably not going to induce as many whiffs either. That’s not to say that he couldn’t learn a new approach, and the good news is that this potentially swift decline doesn’t seem imminent. As you know, his four-seamer averaged 94.8 mph in 2025 (and played even faster), but his fastball velocity has actually been trending up over the past few seasons. It performed well even in 2022, when it averaged just 92.9 mph. That’s a reassuringly large margin for error. On the other hand, the inefficiency of his approach means that he throws tons of pitches; 8,991 over the past three years, to be exact. That’s the fifth most in the game, and it’s fair to wonder whether he might one day, you know, get tired.
Peralta halved his slider usage in 2025, throwing it just under 10% of the time. He didn’t really throw it to lefties at all, and against righties, he threw all three of his non-fastballs roughly 16% of the time.
Brozdowski posited that Peralta lost feel for his slider, noting its inconsistent amount of horizontal break. It has shifted so much that in some years, some pitch classifications split it up into a slider and a sweeper. Regardless, Stuff+ and StuffPro both regard the pitch as Peralta’s best, and Brozdowski hypothesized that the Mets will try to help him figure it out and return it to its place of prominence. Even if he doesn’t find another gear, he still slides in as the top pitcher in a Mets rotation that completely fell apart in the second half in 2025, and projects as average in 2026. That’s not to say it’s without upside.
The Mets have several starters whose names any baseball fan will know. It starts with Nolan McLean and Jonah Tong, who made their debuts in 2025. McLean looks ready to contribute right away in 2026. Kodai Senga has a career 3.00 ERA and 3.82 FIP in MLB. After a shoulder capsule strain and a calf strain cost him nearly the entire 2024 season, his velocity dropped and his strikeout rate cratered last year, when he also dealt with a hamstring strain. As a result, the projections peg him for an ERA that’s dangerously close to 4.00. But if he finds his old form, he’s a star.
In his first season as a starter, Clay Holmes posted a solid 3.53 ERA, but his 4.11 FIP told a different tale, and the peripherals were scary. The velocity of his sinker, his most-used pitch, fell by 2.9 mph as he transitioned from high-leverage reliever to starter. His strikeout rate, which had averaged nearly 25% to that point in his career, dropped to 18%. Holmes is entering his age-33 season, and it’s hard to know how much improvement to expect from him with one year of starting experience under his belt.
Despite underperforming his peripherals in a major way in 2024, David Peterson seems solid as ever, and he’ll make $100,000 more than Peralta in his final year of arbitration. An oblique strain blew up Sean Manaea’s 2025 season, limiting him to 12 ugly starts, but he’s just one year removed from a 2024 season in which he earned a Cy Young vote. That’s six names and nearly as many question marks, but this rotation certainly isn’t devoid of talent. It’s not hard to envision this staff being good, and it’s not hard to envision it being quite bad. If nothing else, Peralta adds some much-needed stability.
Tobias Myers is 27, and across his two big league seasons, he has made 31 starts and 18 relief appearances, putting up a 3.55 ERA and 3.92 FIP. An early-season oblique strain cost Myers some time in 2025, and he got sent down after a rough start. However, he came back up in a relief role in July, and over the last three months of the season, he posted a 2.64 ERA and 3.49 FIP. With a 93.5 mph fastball, his stuff grades out as roughly average, and he doesn’t strike out many batters. He also had the odd distinction of tying for the splitter that had the most induced vertical rise in baseball at 10.5 inches.
Myers throws six pitches: a four-seamer, cutter, slider, splitter, changeup, and curveball. When you look at his extremely steep 61-degree arm angle and the huge rise on his four-seamer, you start to wonder why he doesn’t embrace this North-South profile and throw his curveball much more often. He was blocked in Milwaukee, and if all goes to plan, he’s likely to be blocked in New York too, and maybe he’s shown all that he has to offer. Still, though it might not be the smartest thing in the world to assume that some other team is going to do a better job of developing a pitcher than the Brewers, it’s fair to say that Myers doesn’t seem like a finished product.
The Mets spent the beginning of the offseason upgrading their bullpen and replacing Pete Alonso. Over the past several days, they’ve reminded everyone just how much of a juggernaut they really are. What’s $8 million (and the resultant $8.8 million luxury tax hit) to a team that just snatched Bo Bichette away from the Phillies for (in theory) three years and $126 million? It’s entirely possible that the Brewers will turn Sproat into their latest ace, and that in a year or two he’ll start a playoff game against the Mets, just like Peralta did in 2024. But the Mets are trying to win this season, and now that he’s not in Milwaukee, David Stearns has the luxury of leaving tomorrow’s problems for tomorrow.

The baseball industry loves its pitching prospects — and sometimes seems to love dreaming on them by using them as trade chips almost as much as it does actually letting them pitch. Considered to have one of the best curveballs in the game from the outset of his professional career, Gio Gonzalez was traded three times before he’d thrown a major league pitch, and five times during a career that ended just after he turned 35. Along the way, the undersized southpaw made two All-Star teams, received Cy Young votes twice, and helped his teams reach the playoffs five times. While he wasn’t always easy to watch given his high walk rates, his ability to miss bats was a testament to the quality of his stuff.

Giovany Aramis Gonzalez was born on September 19, 1985 in Hialeah, Florida, a city in Miami-Dade County where roughly three-quarters of the population is of Cuban ancestry. He’s the oldest of six children of Max and Yolanda (Yoly) Gonzalez. Max, a first-generation Cuban-American, installed billboards and owned a scooter shop, while Yoly, an immigrant from Cuba, worked at various jobs to help the family make ends meet.
Gio was just four years old when his parents introduced him to baseball. Growing up, he played sandlot baseball with neighborhood kids in a narrow, rocky strip of land behind the family’s townhouse. “We broke so many windows that I found a guy who would replace them for 15 bucks apiece,” Yoly recalled in 2011.
“Max grew up tough, never got to play as much ball as he wanted and, when it rained on too-rare Sundays when he had a game as a child, he broke down in frustration and cried. But he never stopped studying the sport,” wrote the Washington Post’s Thomas Boswell in 2012. When his eldest son showed an aptitude for the game, Max taught him the curveball that would become his signature. Read the rest of this entry »

Along with Prince Fielder, who debuted in mid-2005 and joined the lineup as a regular the following season, Ryan Braun was a transformative figure in the history of the Brewers. Including its one-off season as the Seattle Pilots, the franchise made the playoffs just twice in its first 38 campaigns, back in 1981 and ’82. With Braun — the club’s first-round pick in 2005 — bopping 34 homers in just 113 games en route to NL Rookie of the Year honors in ’07, the Brewers finished above .500 for the first time in 15 years, and the next year, with Braun moving from third base (where he was terrible) to left field and making his first of six All-Star teams, they made the playoffs as the National League Wild Card. They would go on to qualify for the playoffs four more times during Braun’s career, with division titles and trips to the National League Championship Series in 2011 and ’18, though they fell just short of trips to the World Series.
Braun won NL MVP honors in 2011 and went on a memorable October run before the Brewers were eliminated, then led the league in home runs while finishing as runner-up in the voting the following year. He accumulated at least 30 homers and 30 steals in both seasons, but by that point, the legitimacy of those accomplishments was in question. In December 2011, less than a month after he beat out Matt Kemp for MVP, Major League Baseball suspended him for 50 games for testing positive for elevated levels of testosterone, later discovered to be synthetic; the sample had been taken after the Brewers’ first postseason game. With a spokesman citing “highly unusual circumstances,” “Ryan’s complete innocence,” “impeccable character and no previous history” of violations, Braun challenged the suspension. In February 2012, an arbitration panel overturned it due to a technicality involving the delay between when he submitted his sample and when the collector, a man named Dino Laurenzi Jr., sent it to the lab.
Both that reversal and Braun’s following actions — smearing Laurenzi both publicly and privately, even alleging that the collector was anti-Semitic (Braun’s father is Jewish, and Braun publicly embraced his Jewish heritage) — are without parallel in MLB’s long steroid saga. What’s more, Braun’s indignation and proclamations of innocence turned out to be a total sham; in 2013, he was discovered to have received PEDs through the Biogenesis Clinic, and earned a 65-game suspension. Thereafter, he publicly apologized, made amends with Laurenzi, and did his best to rehabilitate his image and demonstrate solid citizenship by continuing his involvement in several charitable organizations; he even earned multiple nominations for the Roberto Clemente Award. While he continued to play a supporting role on some very good Brewers teams (and some not-so-good ones), age and injuries limited his availability and effectiveness. Read the rest of this entry »
