William Contreras grew up in Puerto Cabello, Venezuela, watching his older brother Willson pursue a career in professional baseball. Years later, both brothers would become Major League All-Stars, establishing themselves among the sport’s most accomplished catchers.
Now William has become one of the biggest names in the 2026 World Series.
The 28-year-old Milwaukee Brewers catcher has enjoyed an extraordinary postseason, combining powerful hitting, impressive defensive work and a remarkable ability to make a difference in the most important moments.
And William Contreras earned his own place in Brewers history with a World Series performance worthy of the MVP award. The Venezuelan catcher, affectionately known as “Wild Bill,” was outstanding at the plate and behind it, delivering clutch hits, expertly guiding Milwaukee’s pitching staff and showing remarkable instincts when challenging ball-and-strike calls. His older brother Willson, himself a World Series champion with the Chicago Cubs in 2016, was in attendance for Game 5 to cheer him on. For a franchise that has celebrated legendary players such as Robin Yount, Paul Molitor and Cecil Cooper, Contreras represents another wonderful chapter in Milwaukee baseball. After years of helping the Brewers chase a championship, he helped bring the trophy home.
Known affectionately as “Wild Bill,” Contreras has become central to Milwaukee’s championship run, giving fans plenty of reasons to celebrate the player behind the catcher’s mask.
And his journey began thousands of miles from Wisconsin.
Born December 24, 1997, Contreras grew up in Venezuela in a family that knew the demands of pursuing professional baseball. His older brother Willson would eventually reach the Major Leagues with the Chicago Cubs, while William began developing his own ambitions.
In February 2015, the Atlanta Braves signed William as an international free agent.
He was just 17.
Contreras began his professional career in the Dominican Summer League, where he immediately demonstrated his offensive potential, batting .314 during his first season. From there, he progressed through Atlanta’s minor-league system, steadily developing the skills required of a Major League catcher.
His big opportunity arrived on July 24, 2020, when he made his Major League debut for the Braves.
The following season, Contreras was part of Atlanta’s 2021 World Series championship team, giving him an early opportunity to experience baseball’s biggest stage.
He continued developing as a hitter and catcher, earning his first All-Star selection in 2022.
That appearance produced a wonderful family milestone.
William and Willson became the 15th pair of brothers in Major League history to be selected as All-Stars, bringing their childhood dreams together on one of baseball’s biggest stages.
For a family from Venezuela, it was an extraordinary achievement.
And the next chapter of William’s career would take him to Milwaukee.
In December 2022, the Braves traded Contreras to the Brewers as part of a three-team deal involving the Oakland Athletics.
The move would prove enormously important for Milwaukee.
Contreras quickly established himself as one of the National League’s most productive catchers, combining reliable offensive performances with improving defensive skills.
In 2023, his first season with the Brewers, he batted .289 across 141 games and won the National League Silver Slugger Award at catcher.
He followed that performance with an even stronger 2024 campaign.
Appearing in 155 games, Contreras batted .281 and finished fifth in National League Most Valuable Player voting. He also earned another Silver Slugger Award, confirming his status as one of baseball’s most dangerous offensive catchers.
The consistency was impressive, especially considering the physical demands of playing behind home plate.
Catchers are responsible for handling pitchers, studying opposing hitters and managing the enormous mental and physical demands of every game.
Contreras has developed into a player capable of contributing in all those areas while remaining a major offensive threat.
And during the 2026 postseason, he’s taken that combination to another level.
Entering the final stages of the World Series, Contreras had produced a .383 postseason batting average with three home runs, eight runs batted in and an outstanding 1.059 OPS.
Those are exceptional numbers at any point in the season.
Doing it under the pressure of October baseball makes the achievement even more impressive.
Contreras has also demonstrated remarkable confidence behind the plate, becoming especially effective at using Major League Baseball’s automated ball-strike challenge system.
The technology allows players to challenge certain ball-and-strike calls, with a computerized system determining whether the original ruling should stand.
For a catcher who already spends every inning studying the strike zone, knowing when to challenge can create an important competitive advantage.
Contreras has drawn attention for his ability to recognize questionable calls and make effective use of the system during Milwaukee’s playoff run.
It’s another example of how his contributions extend beyond hitting.
And his performances have helped make the Brewers’ 2026 season a historic one.
Milwaukee finished the regular season with a franchise-record 103 victories, establishing itself as one of baseball’s strongest teams.
After defeating the San Diego Padres in the National League Division Series, the Brewers swept the Los Angeles Dodgers in four games to reach the World Series for the first time since 1982.
That set up a remarkable championship matchup against the Tampa Bay Rays, with both franchises looking for their first World Series title.
Milwaukee won the opening three games, putting itself on the brink of a championship before Tampa Bay produced a dramatic extra-innings victory in Game 4.
Through it all, Contreras remained one of Milwaukee’s most reliable performers.
His success at the plate and contributions behind it helped establish him among the leading candidates for the Willie Mays World Series Most Valuable Player Award.
That recognition reflects just how important he’s become to the Brewers.
But there’s another aspect of Contreras’ story that makes his rise especially memorable.
His brother Willson has enjoyed a distinguished Major League career of his own, winning the 2016 World Series with the Chicago Cubs and earning multiple All-Star selections.
The brothers have shared the experience of reaching baseball’s highest level while following different paths through the sport.
In 2026, both earned All-Star selections again, demonstrating the extraordinary consistency of a family that has produced two standout Major League players.
Away from the field, William became engaged to Nixzali Adames, the sister of former Brewers teammate Willy Adames, adding another personal connection to Milwaukee’s baseball community.
His career has already taken him from Venezuela to Atlanta and then to Wisconsin, bringing opportunities and experiences that would have seemed extraordinary when he first signed professionally at 17.
And now, Milwaukee fans have embraced him as one of the defining personalities of their championship team.
The nickname “Wild Bill” suits a player whose confidence, intensity and unmistakable presence have become familiar parts of Brewers baseball.
He has grown from a promising young catcher into an All-Star, a two-time Silver Slugger winner and one of the most important performers in the sport’s biggest series.
For William Contreras, the journey has involved years of work, family inspiration and the determination required to succeed at baseball’s highest level.
And for the fans who have watched him become one of Milwaukee’s brightest stars, it’s a remarkable story worth celebrating.
