The Brewers’ First Base Possibilities

The Brewers have struggled to find competent first base play for the entirety of this decade. Not since Prince Fielder in the early 2010s has the club had a standout contributor at the position for more than a season. Milwaukee’s regular first baseman (by games played) hasn’t exceeded 1.0 WAR (per Baseball Reference) in a season since Eric Thames in 2019. The team has won the NL Central in four of the last five years, but they’ve shuffled through journeymen and platoon bats at the cold corner during that span.

Andrew Vaughn might be the answer. A mid-June trade from the White Sox seemed to revive the former third overall pick. Vaughn’s underwhelming career hit rock bottom in May, when he was demoted by Chicago after hitting .189 over the first two months of the season. The White Sox dealt him to the Brewers for Aaron Civale, which says a lot about his value at the time.

Rhys Hoskins sprained his thumb in early July, opening the door for a Vaughn promotion. He joined the big-league club and immediately hit the ground running. Vaughn launched a three-run homer off Yoshinobu Yamamoto in his first at-bat with the Brewers. He went on to post a 1.157 OPS in July. After hitting five home runs in 48 games with the White Sox to start the season, Vaughn left the yard five times in his first 15 games with the Brewers.

Vaughn cooled off considerably in August, slashing .250/.320/.375. He managed just six extra-base hits in 29 games. A day off to begin September seemed to do Vaughn some good, as he heated back up to close the season. The 27-year-old hit .368 with a .509 SLG over the last month of the campaign. His performance was enough to bump Hoskins off the NLDS roster. Vaughn had a solid series against the Cubs, popping two homers and driving in four runs. He then went 0-for-12 in a four-game NLCS sweep by the Dodgers.

Despite the hitless series against the L.A., Vaughn heads into 2026 as the top candidate to hold down first base for the Brewers. The club didn’t pick up its end of the mutual option with Hoskins, so Vaughn and Jake Bauers are the only primary first basemen on the roster. Catcher William Contreras and utilityman Andruw Monasterio also have a bit of experience at the position. It seems like Vaughn’s job to lose, but he’s got a lengthy MLB track record of mediocrity. Here’s how first base could play out for Milwaukee in 2026…

Vaughn runs away with the job

The reason behind Vaughn’s takeoff in Milwaukee could be as simple as a change of scenery for a former top pick on a struggling team. However, he did make some clear improvements this past season. He’d always hit the ball hard (46.6% career hard-hit rate), it just hadn’t translated into much production. The guy getting 60 raw power grades as Chicago’s top prospect never hit more than 21 home runs with the club.

Milwaukee was able to get Vaughn to turn his hard contact into better results in multiple ways. The young slugger posted career bests in line drive rate (25.2%), pull rate (37.5%), and pulled air rate (18%) this past season. Those marks are still right around league average, but they’re a solid improvement on Vaughn’s previous work. He also ranked in the 85th percentile in launch angle sweet spot rate and in the 92nd percentile in squared-up rate.

It wasn’t just the batted balls, either. Vaughn took significant steps forward in terms of plate discipline with Milwaukee. After striking out a career-worst 22.3% of the time with Chicago to open the year, he cut that number to 14.6% with the Brewers. He also pushed his walk rate up to 9.4%. Vaughn hasn’t had a walk rate above 7% since his rookie season in 2021.

There’s a chance July and September were the “new” Vaughn, and he’s just going to be a high-.800s OPS bat for the duration of his prime. The pedigree was evident, considering his legendary college career and the draft capital invested in acquiring him. It just took five years and a new home to make good on it.

Vaughn regresses, but the lineup makes up for it

Milwaukee’s offense took a unique shape in 2025. The club didn’t have a regular with an OPS over .800 for the full season, but also had just one everyday player with a mark below .700 (glove-first Joey Ortiz at .593). The result was a team that finished third in scoring behind only the Yankees and Dodgers. Isaac Collins was dealt to Kansas City, but the rest of the group should be back next season. Barring an offseason addition, some combination of Bauers, Garrett Mitchell, and Blake Perkins will fill the void left by Collins in the outfield.

The supportive offensive environment could allow Vaughn to exist in the lineup as a moderately productive piece. That’s basically what he was in Chicago. He never had a truly standout season, but his worst year with the team still resulted in a 93 wRC+. At the very least, he could form a strong platoon with Bauers at first base. Vaughn has always hit lefties, even in his White Sox days. He has a career .787 OPS against southpaws, compared to .702 versus righties.

This outcome hasn’t hindered Milwaukee in the past, as they’ve gotten by with decent contributions from the likes of Hoskins, Rowdy Tellez, and Daniel Vogelbach. Vaughn is set to hit free agency after the 2027 season. Milwaukee could ride this out at a reasonable price and let him walk when the time comes. MLBTR contributor Matt Swartz projects Vaughn to make $7.8MM in arbitration this year.

Tyler Black, come on down

Vaughn was unplayable as recently as May of this past season. Those struggles briefly returned in August with the Brewers. A player getting a jolt after going from the cellar to a competitive club, then reverting to previous form, certainly wouldn’t be an unheard-of outcome.

A Vaughn flameout would likely lead to a renewed opportunity for Black. The 25-year-old has put together solid results in the minors, but has only made 23 appearances in the majors. Black struggled in his brief 2024 debut, then only played a handful of games with the Brewers this past season.

There are questions about Black’s ability to consistently make contact at the highest level. He also might not be a long-term defensive fit at first base (or anywhere else). It just seems like Milwaukee needs to exhaust Black as a possibility before it’s too late. He’s down to one minor league option. He’s already in his mid-20s. MLB.com had Black ranked fourth among the Brewers prospects as recently as 2024. He had a 117 wRC+ at Triple-A that year. He’s shown enough to get an extended look in the big leagues.

If it’s not Black waiting in the wings, maybe it’s Luke Adams? The 21-year-old reached Double-A by the end of last season. He put up a stellar 157 wRC+ across three minor league levels in 2025. Adams kept it rolling in the Arizona Fall League, posting a 1.039 OPS in 16 games. MLB.com has Adams at No. 8 in Milwaukee’s prospect rankings heading into next season. He could be next up if Vaughn falters and Black doesn’t get the nod.
