Coby Mayo Bio
Coby Gerald Mayo (born December 10, 2001) is an American professional baseball player who serves as a first baseman and third baseman for the Baltimore Orioles of Major League Baseball (MLB). He made his MLB debut in 2024 after rising through Baltimore’s farm system, and he is widely regarded as one of the top young power hitters in the organization. Mayo gained national attention even before his professional career began because of his connection to a tragedy at his high school. He has continued to develop his game in the major leagues, gradually finding his footing at the highest level.
Early Life and Background
Coby Gerald Mayo was born on December 10, 2001, and grew up in Parkland, Florida. He attended Marjory Stoneman Douglas High School, the same school that became the site of a devastating shooting in 2018. Mayo was a student on campus during the incident, an experience that shaped his early years and added meaningful perspective to his path in baseball. Despite the emotional weight of that period, he continued to perform on the field and develop into a highly regarded prospect.
As a sophomore in 2018, Mayo batted .388 with seven home runs, establishing himself as a player to watch. In his junior year of 2019, he hit .391 with four home runs, and during the summer of 2019, he was named to the Under Armour All-America Baseball Game at Wrigley Field, a respected showcase for top amateur talent. As a senior in 2020, he batted .455 before the season was cancelled due to the COVID-19 pandemic, ending his high school career on a strong note.
Path to Professional Baseball
Mayo entered professional baseball when he was drafted by the Baltimore Orioles in the fourth round, with the 103rd overall selection, of the 2020 Major League Baseball draft. He signed for $1.75 million, choosing to forgo his commitment to play college baseball at the University of Florida. The decision reflected both the Orioles’ belief in his long-term potential and Mayo’s readiness to begin his pro career.
Because the minor league season was cancelled in 2020 due to the pandemic, Mayo did not play in a professional game after signing. He also missed time at the start of the 2021 season with a knee injury, delaying his official debut. In July 2021, he made his professional debut with the Rookie-level Florida Complex League Orioles before being promoted to the Delmarva Shorebirds of the Low-A East in August. Across 53 games between the two clubs, he slashed .319/.426/.555 with nine home runs, 41 RBI, 14 doubles, and 11 stolen bases, providing a strong first full look at his offensive skill set.
Coby Mayo Career
Early Career (2021–2022)
Following his encouraging debut season, Mayo spent the offseason at Ed Smith Stadium taking part in Baltimore’s fall instructional league, an opportunity that allowed him to refine his approach against advanced competition. To begin the 2022 season, he was assigned to the Aberdeen IronBirds of the High-A South Atlantic League, where he continued to build his offensive identity as a power-hitting infielder.
In late June 2022, he earned a promotion to the Bowie Baysox of the Double-A Eastern League, marking his first taste of upper-level minor league baseball. A back spasm in early July sent him to the injured list, but he rehabbed with the Florida Complex League Orioles and was activated in early August. Across 104 games that season between Aberdeen, Bowie, and the Florida Complex League, Mayo slashed .247/.326/.456 with 19 home runs, 69 RBI, and 20 doubles, numbers that underlined his power potential even as he worked to refine his consistency.
Minor League Breakthrough (2023–2024)
To open the 2023 season, Mayo returned to Bowie and quickly proved he was ready for another step. In early July, he was promoted to the Norfolk Tides of the Triple-A International League, completing his climb from Rookie ball to the highest level of the minors. Over 140 games between Bowie and Norfolk, he slashed .290/.410/.563 with 29 home runs, 99 RBI, and 45 doubles, finishing the year as one of the most productive hitters in Baltimore’s system.
His performance was recognized when he won the 2023 Eastern League Most Valuable Player Award, a milestone that confirmed his status as one of the organization’s cornerstone prospects. He entered 2024 as a non-roster invitee to Orioles spring training, where he batted .326 with one home run and 11 RBI, putting himself in position for a midseason call-up. He opened the year at Norfolk, where he hit .301/.375/.586 with 20 home runs and 61 RBI in 77 games, earning the 2024 International League Top MLB Prospect Award.
Major League Debut and Orioles Tenure (2024–Present)
On August 2, 2024, Mayo was promoted to the major leagues for the first time, fulfilling a long-anticipated arrival in Baltimore. His first MLB hit came on August 14, 2024, a fifth-inning leadoff single to left field off DJ Herz that ended an 0-for-16 slump during a 4–1 home win over the Washington Nationals. He was optioned back to the Tides the following day, then recalled on September 1 after Ramón Urías was placed on the injured list. In 17 appearances during his rookie campaign, Mayo batted .098, a difficult start that still represented an important learning experience.
Mayo was optioned to Triple-A Norfolk to begin the 2025 season, where he worked to adjust to major league pitching. He returned to the Orioles and on June 27, 2025, he hit his first career home run off José Caballero of the Tampa Bay Rays, a milestone that signaled his growing comfort at the plate. He played in 85 games for the Orioles in 2025 and batted .217 with 11 home runs, 28 RBIs, and 12 doubles, establishing a more stable foundation for his ongoing major league career.
Notable Events and Milestones
One of the defining early moments of Mayo’s career came on August 14, 2024, when he recorded his first major league hit in front of the Baltimore home crowd. His first career home run, hit off José Caballero on June 27, 2025, marked another long-awaited milestone, and his back-to-back minor league MVP awards in 2023 and 2024 underscore the consistency of his offensive production as he has moved up the organizational ladder.
Coby Mayo Career Wins and Honors
Although Mayo’s major league career is still in its early chapters, he has already collected meaningful individual recognition. His 2023 Eastern League Most Valuable Player Award and 2024 International League Top MLB Prospect Award highlight the respect he has earned throughout the Orioles’ development pipeline, while his first MLB hit and first career home run stand as personal benchmarks in his young major league tenure.
Minor League Honors
Mayo’s 2023 season with Bowie and Norfolk was a showcase of his power and plate discipline, leading to the Eastern League Most Valuable Player Award.

Major League Firsts
Mayo’s first major league hit arrived on August 14, 2024, against the Washington Nationals, ending a brief but demanding adjustment period. His first career home run followed on June 27, 2025, off Tampa Bay’s José Caballero, giving him a long-awaited power milestone at the game’s highest level.
Coby Mayo Family
Family Background and Personal Life
Public details about Coby Gerald Mayo’s immediate family are limited, and he has largely kept his personal life private. His experience as a student at Marjory Stoneman Douglas High School during the Parkland shooting is the most widely discussed chapter of his personal story, and it remains a defining part of how he is viewed off the field. He is known to have focused much of his early adult life on the demands of professional baseball after committing to the Orioles in 2020.
2025 Season Performance
Mayo began the 2025 season back at Triple-A Norfolk, a decision that gave him a chance to reset after his challenging 2024 debut. He returned to Baltimore later in the year and gradually found his rhythm, highlighted by his first career home run on June 27, 2025, off José Caballero of the Tampa Bay Rays. Across 85 games with the Orioles in 2025, he batted .217 with 11 home runs, 28 RBIs, and 12 doubles, showing the kind of power production the organization has long expected from him.
His growth in 2025 reflected a more controlled approach at the plate and a better understanding of major league pitching, and his role within the Baltimore lineup continued to expand as the season progressed. The combination of his power upside, his prior minor league awards, and his accumulating major league experience positioned him as a player the Orioles are counting on for the next phase of their competitive window.
