Andruw Monasterio Bio
Andruw José Monasterio (born May 30, 1997) is a Venezuelan professional baseball infielder. He currently plays in Major League Baseball (MLB) for the Boston Red Sox after beginning his big-league career with the Milwaukee Brewers. Monasterio has spent time across the diamond, primarily at second base and shortstop, and is regarded as a glove-first middle infielder with a steady bat.
Early Life and Background
Monasterio was born on May 30, 1997, and grew up in Venezuela, a country long known for producing skilled baseball players. From a young age, he gravitated toward the middle of the infield, learning the footwork and arm action required to play shortstop at a competitive level. The Venezuelan baseball tradition, rich with academies and winter league opportunities, helped shape his early development.
At age 17, Monasterio tried out for the Chicago Cubs at the organization’s Venezuelan academy. The Cubs were impressed with his hands, range, and baseball instincts, and they signed him to a contract on March 7, 2014. That signing launched his path through professional baseball and set the tone for a career built on defense and contact hitting.
Path to Baseball
Monasterio began his professional journey in the Venezuelan Summer League, the typical first stop for Latin American signees adjusting to a full pro schedule. In 2015, he moved to the rookie-level Arizona League Cubs, where he played 42 games and hit .252/.346/.348 with one home run and 16 runs batted in, showing the on-base skills that would become a hallmark of his game.
Originally a shortstop, Monasterio began seeing regular time at second base in 2016 with the Single-A South Bend Cubs. Across South Bend and the Low-A Eugene Emeralds, he played 65 games, hit .247/.294/.308 with one home run, 23 RBI, and eight stolen bases, and continued to sharpen his defense up the middle. His steady progression positioned him as a reliable, if unspectacular, middle-infield prospect within the Cubs system.
Andruw Monasterio Career
Early Career (2014–2017)
After signing with the Cubs in 2014, Monasterio climbed through the lower levels of the minor leagues. In 2017, he played 84 games split between South Bend and the High-A Myrtle Beach Pelicans, posting a .270/.341/.346 line with one home run, 28 RBI, and eight stolen bases. The season reinforced his identity as a contact-oriented hitter who controls the strike zone.
In 2018, Monasterio opened the year at Myrtle Beach and set career highs with three home runs and 36 RBI across 109 games while batting .263/.359/.336. His blend of on-base ability and dependable glove work made him a useful utility piece, even as questions about his long-term power profile persisted.
Washington Nationals Era (2018)
On August 21, 2018, the Cubs traded Monasterio to the Washington Nationals in a deal that brought Daniel Murphy and cash considerations to Chicago. Assigned to the Potomac Nationals of the High-A Carolina League, Monasterio excelled in a small sample, hitting .308 with five RBI and two stolen bases in 13 games. During that period, Baseball scout Adam McInturff of 2080 Baseball described him as a high-floor prospect with above-average defense but limited offensive power.
Cleveland Indians Era (2018–2021)
Monasterio’s stay in Washington was brief. On November 30, 2018, Jefry Rodríguez, Daniel Johnson, and a player to be named later were sent to the Cleveland Indians in a trade for Yan Gomes. On December 17, Monasterio was officially sent to Cleveland as that unnamed player. He spent 2019 with the Double-A Akron RubberDucks, playing 70 games and batting .217/.279/.253 with one home run and 11 RBI despite a short oblique injury.
The 2020 minor league season was canceled because of the COVID-19 pandemic, leaving Monasterio without a game that year. He elected free agency on November 2, 2020, then re-signed with Cleveland on a minor league deal on November 9. In 2021, he played 107 games between Akron and the Triple-A Columbus Clippers, hitting a combined .287/.371/.442 with eight home runs, 61 RBI, and seven stolen bases, before electing free agency again on November 7, 2021.
Milwaukee Brewers Era (2022–2025)
On November 10, 2021, Monasterio signed a minor league contract with the Milwaukee Brewers organization. In 2022, playing for the Double-A Biloxi Shuckers, he delivered one of the highlights of his minor league career on August 1, hitting a walk-off grand slam to defeat the Montgomery Biscuits in 11 innings. Across Biloxi and the Triple-A Nashville Sounds, he slashed .271/.364/.406 with nine home runs, 44 RBI, and 15 stolen bases in 110 games.
In 2023, Monasterio opened the season at Nashville and was hitting .274/.410/.400 when his path to the majors finally opened. On May 27, 2023, he was added to the 40-man roster and promoted after Willy Adames was placed on the concussion list. He made his MLB debut on May 28, recorded his first career hit on May 30, his 26th birthday, and hit his first major league home run on June 4, a three-run shot off Cincinnati Reds pitcher Ben Lively. Later that summer, on July 16, he delivered his first career go-ahead RBI with a single off Reds All-Star closer Alexis Díaz. He finished the year appearing in 92 games with a .259/.330/.348 line, three home runs, and 27 RBI.
In 2024, Monasterio made the Brewers’ Opening Day roster and started on Opening Day before being optioned to Nashville. After brief returns to the majors, he played 59 games for Milwaukee and slashed .208/.303/.272 with one home run, 16 RBI, and six stolen bases. In 2025, he opened the year back at Nashville before being recalled on May 9, and on July 12 he scored the walk-off run in a 6-5 comeback victory over the Washington Nationals during a seven-game Brewers winning streak. Across 68 regular-season appearances, he batted .270/.319/.437 with four home runs, 16 RBI, and two stolen bases.
Boston Red Sox Era (2026–Present)
On February 9, 2026, the Brewers traded Monasterio, Caleb Durbin, Anthony Seigler, and a compensation round draft pick in the 2026 MLB draft to the Boston Red Sox in exchange for Kyle Harrison, David Hamilton, and Shane Drohan. Through June 17, 2026, he wears No. 32 for Boston and has posted a .248 batting average with 10 home runs and 70 runs batted in, showing more offensive thump than at any previous point in his career.
Driving Style and Strengths
Monasterio is best known for his above-average defense up the middle, smooth actions at second base, and a contact-driven approach at the plate. He walks at a healthy clip, uses the whole field, and provides steady baserunning instincts, though his raw power has always been the most debated part of his profile.
Notable Events and Milestones
His career has been punctuated by signature moments, including his 2022 walk-off grand slam at Double-A Biloxi, his first MLB hit on his birthday in 2023, his first major league home run off Ben Lively, and his walk-off run-scoring play during the Brewers’ 2025 midseason winning streak. Each milestone reinforced his reputation as a clutch, defense-first middle infielder.

Across Double-A Biloxi and Triple-A Nashville in 2022, he combined for a .271/.364/.406 line, and his 2023 stint at Nashville featured a .274/.410/.400 mark before his promotion. In the majors, his .270/.319/.437 line over 68 appearances in 2025 and his .248 average with 10 home runs and 70 RBI early in 2026 represent the strongest offensive stretches of his big-league tenure.

2025 Season Performance
Monasterio opened the 2025 season at Triple-A Nashville before being recalled to the Brewers on May 9.

Used as a flexible piece who could spell starters and play multiple positions, Monasterio gave Milwaukee reliable at-bats and a steady glove. His ability to draw walks and put the ball in play fit the Brewers’ contact-and-defense identity, even as his power remained a work in progress.
Following the season, Monasterio was traded to the Boston Red Sox on February 9, 2026, in a package headlined by Caleb Durbin. The move signaled continued belief in his defensive upside and contact skills, setting the stage for an expanded role at Fenway Park.
