Carson Spiers Bio
William Carson Spiers, known professionally as Carson Spiers, is an American professional baseball pitcher who has competed in Major League Baseball (MLB) for the Cincinnati Reds. Born on November 11, 1997, he made his major league debut in 2023 and has since worked to establish himself within the organization as a versatile arm capable of working in both starting and relief roles. Standing out for his resilience and competitive drive, Spiers has progressed through the Reds’ minor league system while adapting to the demands of professional pitching.
A graduate of Clemson University, Spiers built his reputation as a reliable relief pitcher during his collegiate career before signing with the Reds as an undrafted free agent in 2020. Although his professional journey was delayed by the cancellation of the minor league season during the COVID-19 pandemic, he steadily advanced through the organization’s affiliates. His path reflects a combination of perseverance, family baseball tradition, and consistent on-field production.
Early Life and Background
Carson Spiers was born on November 11, 1997, and raised in Greenville, South Carolina, a community with a deep appreciation for baseball and football. He attended Greenville High School, where he was a dual-sport athlete, playing baseball as a third baseman and competing in American football as a quarterback. His performance in both sports drew attention from college recruiters, illustrating his natural athleticism and competitive instinct from a young age.
Baseball was a central part of Spiers’ family life, and that heritage played a meaningful role in shaping his career path. His uncle, Bill Spiers, played baseball at Clemson and later competed in the major leagues, serving as a direct link to professional baseball. His father, Michael, and his grandfather, Bud, also played baseball for the Clemson Tigers, while his cousin, Will, served as a punter on Clemson’s football team. This multi-generational connection to the Clemson program made the university a natural fit for Spiers when he chose to continue his athletic career.
Path to Professional Baseball
After high school, Spiers enrolled at Clemson University, where he joined the Clemson Tigers baseball program. He made three appearances as a pitcher during his freshman year in 2017 and returned the following season as a middle reliever, posting a 2.08 earned run average (ERA). In the summer of 2018, he played collegiate summer baseball with the Falmouth Commodores of the Cape Cod Baseball League, where he impressed with a 0.84 ERA. By 2019, he had earned the role of closer for Clemson.
Across his collegiate career from 2017 to 2020, Spiers compiled a 7–7 win–loss record, a 2.47 ERA, 19 saves, and 103 strikeouts in 109 and one-third innings pitched, all in relief roles. Following the cancellation of the 2020 MLB Draft’s typical structure due to the pandemic, Spiers went unselected in the shortened draft. The Cincinnati Reds signed him as a free agent, but he did not appear in a game that year after the minor league season was canceled.
