Mason Black Bio
Mason Peter Black is an American professional baseball pitcher for the Kansas City Royals of Major League Baseball. He previously played in MLB for the San Francisco Giants. A right-handed starter, Black has moved quickly through the minor leagues since being drafted in 2021.
Born and raised in Pennsylvania, Black developed into a polished college pitcher at Lehigh University before entering professional baseball. He is recognized for his strikeout ability and his rapid climb from Low-A ball to the major leagues in under three full seasons.
Early Life and Background
Early Life and Background
Mason Peter Black was born on December 10, 1999, in Archbald, Pennsylvania. He grew up in the small Lackawanna County community and attended Valley View High School, where he quickly emerged as one of the top pitching prospects in the region.
During his high school career, Black put together a standout statistical line, finishing with a 12-5 win-loss record, a 1.19 earned run average, and 123 strikeouts. His performance drew the attention of college recruiters and helped set the stage for his future in the sport.
Black came from a supportive family environment in northeastern Pennsylvania, and his early exposure to competitive baseball through local leagues and school programs helped shape his work ethic. Those formative years laid the groundwork for the discipline he would later bring to his college and professional careers.
Path to Baseball
Path to Baseball
After high school, Black enrolled at Lehigh University, where he pitched for the Lehigh Mountain Hawks for three seasons. His freshman year in 2019 gave him a taste of college competition, and he followed it up by playing collegiate summer baseball for the Brewster Whitecaps of the Cape Cod Baseball League, where he was named a league all-star.
Black’s sophomore season in 2020 was cut short by the coronavirus pandemic, limiting him to a 1-2 record and a 3.68 ERA in four starts. He stayed sharp that summer by pitching for the Boca Raton Blazers of the South Florida Collegiate Baseball League, gaining valuable innings under challenging circumstances.
As a junior, Black had a breakout year. He was named the Patriot League Pitcher of the Year after going 7-3 with a 3.11 ERA and 95 strikeouts across 72 and one-third innings pitched. That performance cemented his status as one of the top collegiate pitchers in the region and put him firmly on the radar of major league scouts.

The San Francisco Giants selected Black in the third round of the 2021 Major League Baseball draft, using the 85th overall pick on the right-hander out of Lehigh. The pick reflected the organization’s confidence in his strikeout profile and college track record.
Black began his professional career in 2022, splitting the year between the San Jose Giants of the Low-A California League and the High-A Eugene Emeralds. Across 24 starts and 112 innings, he went 6-4 with a 3.21 ERA and 136 strikeouts, earning recognition as a Minor League Organization All Star.

He made 29 starts and posted a 4-9 record with a 3.71 ERA and 155 strikeouts in 123 and two-thirds innings, showing durability against advanced competition.
Black reached the major leagues on May 6, 2024, when the Giants selected his contract and promoted him to the big league club. He made his debut that same day as the starting pitcher against the Philadelphia Phillies, taking a loss after allowing eight hits and five earned runs with four strikeouts in four and one-third innings in a 6-1 defeat.
His first MLB victory came on September 20, 2024, when he pitched five and two-thirds scoreless innings in a 2-1 win over the Kansas City Royals at Kauffman Stadium. Across nine appearances and eight starts with San Francisco in 2024, Black finished with a 1-5 record, a 6.44 ERA, and 31 strikeouts in 36 and one-third innings.
Kansas City Royals Era (2025-Present)

On November 6, 2025, the Giants designated Black for assignment. Five days later, on November 11, 2025, he was traded to the Kansas City Royals in exchange for Logan Martin, opening a new chapter in his major league career.
Notable Events and Milestones

2025 Season Performance
The 2025 season represented a transitional year for Mason Black. He spent most of the year at the Triple-A level with the Sacramento River Cats, working to refine his command and adjust to the upper-minors competition after his first taste of the major leagues in 2024.
Black’s lone major league appearance of the regular season came with San Francisco, where he allowed five runs with five strikeouts over four innings. He was later designated for assignment on November 6, 2025, and traded to the Kansas City Royals five days later as part of a deal for pitcher Logan Martin.
Looking ahead, Black joins a Royals organization looking to add young arms to its pitching depth. His combination of strikeout ability and starting experience gives him a clear opportunity to compete for a spot in Kansas City’s rotation or bullpen as he begins the next phase of his career.
