Mason Black Bio
Mason Peter Black is an American professional baseball pitcher for the Kansas City Royals of Major League Baseball (MLB). He has previously played in MLB for the San Francisco Giants. The right-handed pitcher was born on December 10, 1999, in Archbald, Pennsylvania, and developed his skills locally before advancing through the minor leagues and reaching the majors. Black was selected by the San Francisco Giants in the third round of the 2021 MLB Draft and made his major league debut in May 2024. He was traded to the Kansas City Royals in November 2025 and continues his professional career in the American League Central division.
Early Life and Background
Black grew up in Archbald, Pennsylvania, a small community in Lackawanna County near Scranton. He attended Valley View High School, where he established himself as a dominant high school pitcher. During his varsity career, Black compiled a impressive record that demonstrated his potential at the next level. His standout performances attracted attention from college programs throughout the Northeast.
Path to Professional Baseball
After graduating from Valley View High School, Black continued his baseball career at Lehigh University in Bethlehem, Pennsylvania. He played for the Lehigh Mountain Hawks baseball team for three seasons beginning in 2019. During his freshman year, he spent the summer playing collegiate summer baseball for the Brewster Whitecaps in the Cape Cod Baseball League, one of the premier wooden-bat leagues for college players. Black was named a Cape Cod Baseball League All-Star during his debut summer, which further showcased his abilities against top collegiate competition.
Black’s junior season in 2021 proved to be his breakthrough campaign at Lehigh. He dominated opposing hitters with a 7-3 win-loss record and a 3.11 earned run average across 72 and one-third innings pitched. He recorded 95 strikeouts during that season, demonstrating his ability to miss bats at the collegiate level. His exceptional performance earned him Patriot League Pitcher of the Year honors, the highest individual award in the conference. The 2020 season was cut short due to the coronavirus pandemic, but Black continued developing by playing for the Boca Raton Blazers of the South Florida Collegiate Baseball League during the summer.
Mason Black Career
Minor League Development (2021-2023)
The San Francisco Giants selected Black in the third round of the 2021 MLB Draft with the 85th overall pick. He signed shortly after being selected and began his professional career in 2022 with the San Jose Giants of the Low-A California League. Black was promoted to the High-A Eugene Emeralds during that same season. Across 24 starts totaling 112 innings between both affiliates, he posted a combined 6-4 record with a 3.21 earned run average and 136 strikeouts. His performance earned him recognition as a Minor League Organization All-Star.
Black spent the entire 2023 season at the Double-A and Triple-A levels, splitting time between the Richmond Flying Squirrels and Sacramento River Cats. In 29 starts covering 123 and two-thirds innings, he compiled a combined 4-9 record with a 3.71 earned run average and 155 strikeouts. The extensive experience against advanced minor league hitters prepared him for a potential major league opportunity.
San Francisco Giants (2024-2025)
Black received his first major league call-up on May 6, 2024, when the Giants selected his contract and added him to the 40-man roster. He made his MLB debut that same day as the starting pitcher against the Philadelphia Phillies at home. Black struggled in his debut, allowing eight hits and five earned runs with four strikeouts across four and one-third innings, receiving a loss in the 6-1 defeat.
Black achieved his first major league win on September 20, 2024, in a memorable performance against the Kansas City Royals at Kauffman Stadium. He pitched five and two-thirds innings of scoreless baseball, surrendering no runs on hits while helping the Giants secure a 2-1 victory. That start represented the high point of his rookie campaign. Overall, Black appeared in nine games including eight starts for San Francisco, compiling a 1-5 record with a 6.44 earned run average and 31 strikeouts across 36 and one-third innings.
Black began the 2025 season with Triple-A Sacramento before receiving a mid-season opportunity with the major league club. He made one appearance for San Francisco during the regular season, allowing five runs with five strikeouts over four innings. The Giants designated Black for assignment on November 6, 2025, ending his tenure with the organization.
Kansas City Royals (2026-Present)
On November 11, 2025, the Kansas City Royals acquired Black from the San Francisco Giants in exchange for minor league player Logan Martin. The trade provided Black with a fresh start in a different organization. The Royals assigned him to Triple-A Omaha Storm Chasers to begin the 2026 season, where he continues to work toward securing a permanent spot in the major league rotation.
Driving Style and Strengths
Black features a low-90s fastball that he commands well, complementing it with a sweeping slider that generates whiffs against both left-handed and right-handed hitters. He also incorporates a changeup into his arsenal to keep opposing hitters off balance. His approach centers on pitch sequencing and inducing weak contact rather than overpowering velocity. His collegiate and minor league track record demonstrates his ability to work deep into games and provide quality innings when his command is sharp.
Notable Events and Milestones
The defining moment of Black’s young major league career remains his first MLB win at Kauffman Stadium against the Royals in September 2024. That performance showed his potential to compete at the highest level when executing his pitches effectively. He also achieved the notable milestone of reaching the majors just three years after being drafted, which represents a reasonable developmental timeline for a college pitcher selected in the third round.

2025 Season Performance
The 2025 season presented challenges for Black during his final months with the San Francisco Giants organization. He reported to Spring Training with Sacramento and began the regular season at Triple-A before receiving a brief opportunity with the major league club. The limited exposure at the highest level made it difficult for Black to build momentum or demonstrate significant improvement.
His lone appearance for San Francisco during the season came with the big club in need of pitching support. The performance did not result in a decision and reflected the ongoing adjustment period Black experienced transitioning from minor league competition to major league hitters. The Giants ultimately made a roster decision in early November, designating Black for assignment.
The trade to Kansas City shortly thereafter opened a new chapter in Black’s career. Reporting to the Royals organization provides him with a fresh environment and the opportunity to compete for a spot in their rotation or bullpen. He began the 2026 campaign with Triple-A Omaha and continues working toward consistent major league contributions with his new club.
