Carson Spiers Bio
William Carson Spiers is an American professional baseball pitcher who currently plays in the Cincinnati Reds organization. Born on November 11, 1997, Spiers made his Major League Baseball debut in September 2023 after being promoted as a COVID-19 substitute. His path to the majors included a solid amateur career at Clemson University and a resilient journey through the minor leagues, where he developed into a versatile relief pitcher capable of both starting and closing roles.
Early Life and Background
Carson Spiers grew up in Greenville, South Carolina, where he attended Greenville High School. During his high school years, he distinguished himself as a two-sport athlete, playing baseball as a third baseman and American football as a quarterback. His athletic abilities attracted college recruitment offers for both sports, demonstrating his versatility and competitive drive from an early age.
Coming from a baseball family, Spiers had strong athletic lineage supporting his development. His uncle, Bill Spiers, played baseball at Clemson University and went on to have a major league career. His father, Michael Spiers, and grandfather, Bud Spiers, also played baseball for the Clemson Tigers, creating a lasting connection to the university program that would shape his future.
Path to Professional Baseball
After graduating from Greenville High School, Spiers chose to continue his baseball career at Clemson University, where he played for the Clemson Tigers from 2017 to 2020. He made just three appearances as a pitcher during his freshman year in 2017 but showed significant improvement the following season, posting a 2.08 earned run average as a middle reliever.
Spiers spent the summer of 2018 playing collegiate summer baseball with the Falmouth Commodores of the Cape Cod Baseball League, one of the premier amateur summer leagues in the country. He excelled in that competition, recording an impressive 0.84 ERA while facing top college talent from across the nation. This performance helped establish him as a legitimate professional prospect.
By 2019, Spiers had earned the role of Clemson’s primary closer, taking on high-pressure situations late in games. Over his four-year collegiate career from 2017 to 2020, he compiled a 7-7 win-loss record with a 2.47 ERA, 19 saves, and 103 strikeouts across 109 and one-third innings pitched, all coming out of the bullpen as a relief specialist.
Carson Spiers Career
Minor League Development (2020–2022)
Despite going unselected in the shortened 2020 Major League Baseball draft due to pandemic-related adjustments, Spiers signed with the Cincinnati Reds as a free agent. Unfortunately, the minor league season was canceled that year because of the COVID-19 pandemic, meaning he did not appear in any professional games during his first year under contract.
Spiers finally began his professional career in 2021, splitting the season between the Single-A Daytona Tortugas and the High-A Dayton Dragons. In 25 total games with 20 starts, he demonstrated his potential by registering an 8-4 win-loss record with a 3.55 ERA and 130 strikeouts across 111 and two-thirds innings pitched.
The following year in 2022, Spiers continued his development by advancing to higher levels of the minor leagues. He split the season between Double-A and Triple-A Louisville Bats, appearing in 27 games with 23 starts. He posted a 4-6 record with a 5.33 ERA and 105 strikeouts across 121 and two-thirds innings, showing he could compete against more experienced hitters.
Breakthrough to the Majors (2023)
After spending his early professional years alternating between starting and relieving roles, Spiers made a significant adjustment in 2023. With the Chattanooga Lookouts of the Double-A Southern League, he transitioned to becoming a full-time relief pitcher, a role that would eventually earn him his major league opportunity.
On September 1, 2023, the Cincinnati Reds promoted Spiers to the major leagues as a COVID-19 substitute. He made his MLB debut on September 3, 2023. In his first two starts with the Reds, he allowed seven runs on ten hits and five walks while recording eight strikeouts across seven innings pitched.
The Reds returned Spiers to the minor leagues on September 10, 2023, but soon selected him to the 40-man roster and promoted him back to the majors on September 14. He finished his rookie campaign with four total appearances, logging a 6.92 ERA with 12 strikeouts across 13 innings of work.
Cincinnati Reds Era (2024–Present)
Spiers began the 2024 season with Triple-A Louisville but received opportunities with the major league club throughout the year. He made 22 appearances with 10 starts for Cincinnati during the regular season, compiling a 5-7 win-loss record and a 5.46 ERA with 80 strikeouts across 90 and two-thirds innings. This full season of major league experience helped him adjust to the level and establish himself as a viable big league option.
The 2025 season presented significant challenges for Spiers. He made three appearances for Cincinnati to begin the campaign but struggled, going 0-2 with a 6.08 ERA and 11 strikeouts across 13 and one-third innings. On April 20, 2025, the Reds placed him on the injured list with a right shoulder impingement syndrome. He was transferred to the 60-day injured list on May 23, interrupting his season.
During his rehabilitation from the shoulder injury, Spiers received difficult news on July 26, 2025, when it was announced he had suffered a UCL injury that required season-ending surgery. Following this setback, the Reds designated him for assignment on November 18, 2025, and non-tendered him on November 21, making him a free agent. However, on November 24, 2025, Spiers re-signed with the Reds organization on a minor league contract, demonstrating his commitment to continuing his baseball career.
Pitching Style and Strengths
Throughout his career, Spiers has demonstrated the ability to pitch effectively in multiple roles. His experience as both a starter and reliever at Clemson and in the minor leagues gave him versatility that translated to the professional level. As a relief pitcher, he showed composure in high-pressure situations, drawing on his experience as Clemson’s primary closer during his college years. His strikeout ability has been a consistent tool throughout his career, averaging more than a strikeout per inning at multiple minor league levels.

Family and Personal Life
Family Baseball Legacy
Carson Spiers comes from a family deeply rooted in baseball tradition, particularly at Clemson University. His uncle, Bill Spiers, carved out a professional career that included time in Major League Baseball, setting an early example for the family. Bill Spiers also played collegiately at Clemson, maintaining the family’s connection to the program.
The Spiers family’s involvement in baseball extends across multiple generations. Carson Spiers’ father, Michael Spiers, played baseball for the Clemson Tigers, continuing the family tradition at the school. Their grandfather, Bud Spiers, also wore the Clemson uniform, making three generations of Spiers men who contributed to the university’s baseball program.
Beyond baseball, the family’s athletic achievements extended to American football. Carson’s cousin, Will Spiers, served as the punter for the Clemson football team, representing yet another sport in which the family excelled at the collegiate level. This multi-sport athletic tradition within the family contributed to Carson’s development as a two-sport athlete at Greenville High School.
Personal Life
Despite the challenges he has faced in his professional career, including injuries and roster transactions, Spiers has demonstrated resilience in pursuing his baseball career. The COVID-19 pandemic disrupted his initial professional plans when the 2020 minor league season was canceled, but he persisted and eventually reached the majors through determination and consistent performance in the minor leagues. His recent re-signing with the Reds organization following surgery reflects his commitment to continuing his career despite significant setbacks.
2025 Season Performance
The 2025 season proved to be the most challenging year of Carson Spiers’ professional career. After beginning the year with the Cincinnati Reds, he struggled through his first three appearances, compiling an 0-2 record with a 6.08 earned run average. The difficulties he experienced early in the season were indicative of larger physical issues that would soon emerge.
In mid-April 2025, Spiers was placed on the injured list with a right shoulder impingement syndrome, a condition that affects the shoulder joint and surrounding tissues. The injury required an extended recovery period, leading to his transfer to the 60-day injured list in late May. This placement meant he would be unavailable to the team for a significant portion of the season.
The setback became season-ending when it was announced in late July that Spiers had suffered a UCL injury during his rehabilitation. The ulnar collateral ligament injury required surgery, ending any hopes of a return to the mound in 2025. Following this injury, the Reds designated him for assignment in November and subsequently non-tendered him, ending his initial tenure on the 40-man roster. However, his quick re-signing with the organization on a minor league contract shortly after becoming a free agent signals his intent to return to competition once he has recovered from surgery and rehabilitation.
