Born on February 11, 1999, in Temperance, Michigan, Wiemer has built his career around a combination of power hitting and base running since being drafted by the Milwaukee Brewers in 2020. He made his major league debut with the Brewers in 2023 and has since appeared in MLB for the Cincinnati Reds and Miami Marlins, in addition to a brief stretch in the Kansas City Royals system.
Standing out as a multi-tool outfielder, Wiemer is recognized for his athleticism, arm strength in the outfield, and ability to contribute both at the plate and on the base paths. Over the course of his professional career, he has played at every level of the minor leagues and has continued to develop his game as a versatile outfielder capable of handling all three outfield positions.
Early Life and Background
Joseph Daryl Wiemer was born on February 11, 1999, in Temperance, Michigan, a small community in the southeastern part of the state near the Ohio border. He grew up in the same area and attended Bedford Senior High School, where he first gained attention as a baseball prospect. His development during these formative years laid the foundation for a future in professional baseball.
Wiemer continued his baseball career at the University of Cincinnati, where he played college baseball for the Cincinnati Bearcats. During his collegiate journey, he also played summer baseball in 2019 with the Harwich Mariners of the Cape Cod Baseball League, one of the most prestigious summer collegiate leagues in the country. His performance there earned him recognition as a league all-star, further boosting his profile ahead of the 2020 MLB draft.
Path to Baseball
Wiemer’s path to professional baseball took shape during his time with the Cincinnati Bearcats, where he showcased the combination of hitting ability, speed, and defensive instincts that defined his game. His summer stint with the Harwich Mariners in the Cape Cod League further sharpened his skills against high-level competition, and being named an all-star confirmed his status as one of the top amateur players heading into the draft.
In the 2020 Major League Baseball draft, the Milwaukee Brewers selected Wiemer in the fourth round, officially launching his professional career. Although he did not appear in any games that year due to the cancellation of the minor league season caused by the COVID-19 pandemic, the foundation for his development within the Brewers organization had been set. His quick progression through the minors over the following seasons reflected the work he had put in during those early stages.

After being drafted by the Milwaukee Brewers in the fourth round of the 2020 MLB draft, Wiemer was unable to make his professional debut that year because the minor league season was canceled due to the COVID-19 pandemic.

Wiemer’s playing style is built around his combination of power and speed, making him a multi-tool threat in the outfield. He has shown the ability to drive the ball to all fields while also being an aggressive and effective base runner, as evidenced by his 30-plus stolen base seasons in the minors. Defensively, he has the arm strength and range to handle all three outfield positions, giving his teams valuable flexibility in roster construction.
Notable Events and Milestones
