Joey Wiemer Bio

Joseph Daryl Wiemer is an American professional baseball outfielder who currently plays in Major League Baseball (MLB). After beginning his career with the Milwaukee Brewers, he has also appeared for the Cincinnati Reds, Miami Marlins, Kansas City Royals organization, and Washington Nationals. Known for his speed and power potential, Wiemer developed into a top outfield prospect during his time in the Brewers minor league system before reaching the majors in 2023.

A graduate of the University of Cincinnati, Wiemer was selected in the fourth round of the 2020 MLB draft by the Milwaukee Brewers. He has since become a journeyman outfielder, moving between organizations while continuing to provide outfield depth and offensive upside at the highest level.

Early Life and Background

Joseph Daryl Wiemer was born on February 11, 1999, in Temperance, Michigan, United States. He grew up in the same small Michigan community where he attended Bedford Senior High School, playing both baseball and other sports during his formative years. His background in the Midwest shaped his early development as an athlete, and his frame and athleticism helped him attract attention from college baseball programs.

Wiemer continued his baseball career at the University of Cincinnati, where he played college baseball for the Cincinnati Bearcats. During the 2019 collegiate summer, he joined the Harwich Mariners of the Cape Cod Baseball League, one of the most prestigious wooden-bat leagues in the country, and was recognized as a league all-star for his performance. His time with the Bearcats and the Mariners established him as a legitimate professional prospect heading into the 2020 draft.

Path to Baseball

Wiemer’s path to professional baseball gained momentum during his college summers, especially his stint with the Harwich Mariners. The Cape Cod League exposure allowed him to test his skills against top amateur competition and demonstrate the combination of power and speed that scouts valued. His draft stock rose as a result, leading to his selection by the Milwaukee Brewers in the fourth round of the 2020 MLB draft.

Because the 2020 minor league season was canceled due to the COVID-19 pandemic, Wiemer did not appear for the Brewers organization that year. He made his professional debut in 2021 with the Single-A Carolina Mudcats before being promoted to the High-A Wisconsin Timber Rattlers. Over 109 games between the two teams, he slashed .295/.403/.556 with 27 home runs, 77 runs batted in, and 30 stolen bases, proving he could handle advanced competition and setting the stage for a rapid rise through the minors.

Joey Wiemer Career

Early Career (2021-2022)

Wiemer’s first full professional season in 2021 was a breakout year. Splitting the year between the Carolina Mudcats and Wisconsin Timber Rattlers, he produced strong numbers across the board, combining power, patience, and baserunning speed. The performance placed him firmly on the Brewers’ prospect map heading into the next year.

In 2022, Wiemer continued his ascent by playing 127 games split between the Double-A Biloxi Shuckers and Triple-A Nashville Sounds. Over 484 at-bats, he hit .256/.336/.465 with 21 home runs, 77 runs batted in, and 31 stolen bases in 34 attempts. The blend of on-base skills, pop, and stolen-base volume convinced the Brewers that he was ready for an opportunity at the major league level.

Milwaukee Brewers Breakthrough (2023)

After narrowly missing out on the Opening Day roster, Wiemer was promoted to the majors by the Brewers on March 30, 2023. He made an immediate impact, hitting a double in his MLB debut against the Chicago Cubs at Wrigley Field on April 1, doing so on the very first pitch he saw in the big leagues. On April 5, he homered for the first time in a win over the New York Mets at American Family Field.

Wiemer continued to deliver memorable moments during his rookie season. On May 13, he delivered a walk-off sacrifice fly against the Kansas City Royals, and on June 6, he notched his first career walk-off hit, a single against the Baltimore Orioles. In 132 games during his rookie campaign, he batted .204/.283/.362 with 13 home runs, 42 runs batted in, and 11 stolen bases, cementing his status as a regular contributor.

He began 2024 with Triple-A Nashville and appeared in 19 games for Milwaukee, slashing .154/.185/.154 with one stolen base and one walk before the team made a roster decision involving him. On July 30, 2024, the Brewers traded Wiemer, Jakob Junis, and cash to the Cincinnati Reds in exchange for pitcher Frankie Montas. In a brief Reds stint, he appeared in two games, walking in his only plate appearance.

Kansas City Royals and Miami Marlins Era (2024-2025)

On November 22, 2024, the Cincinnati Reds traded Wiemer and Jonathan India to the Kansas City Royals for pitcher Brady Singer. Wiemer was optioned to the Triple-A Omaha Storm Chasers to begin the 2025 season, where he made 72 appearances and batted .182/.291/.312 with nine home runs, 38 runs batted in, and 12 stolen bases.

On August 4, 2025, Wiemer was claimed off waivers by the Miami Marlins. The Marlins recalled him on August 16 after Kyle Stowers was placed on the injured list, and he appeared in 27 games for Miami, batting .236/.279/.436 with three home runs and 12 runs batted in. The Marlins designated him for assignment on November 18, 2025.

Washington Nationals Era (2026-Present)

On November 21, 2025, Wiemer was traded to the San Francisco Giants in exchange for cash considerations. He was designated for assignment by San Francisco on December 17, and on January 5, 2026, Wiemer was claimed off waivers by the Washington Nationals, where he wears jersey No. 21.

Wiemer made an immediate impression in Washington. In his first three games with the Nationals, he tied the MLB record for the most consecutive plate appearances reaching safely to start a season, going 10 in a row. He became only the second player in 106 years to achieve this feat, sharing the record with Carlos Delgado from 2002. The streak, which included two home runs, one triple, five singles, and two walks, ended on a groundout on his 11th plate appearance against the Philadelphia Phillies on March 30.

Notable Events and Milestones

Wiemer’s most memorable major league moments include his first MLB hit, a double on the first pitch he saw at Wrigley Field on April 1, 2023, and his first major league home run against the New York Mets. His opening stretch with the Nationals in 2026 stands as one of the most remarkable early-season feats in modern MLB history, matching a long-standing league record for consecutive safe plate appearances to begin a campaign.
