The Royals Acquire Mason Black From The San Francisco Giants

The Kansas City Royals made a minor trade to add pitching depth, acquiring Mason Black from the San Francisco Giants for minor league prospect Logan Martin. Black, a third-round pick in 2021, was designated for assignment by the Giants. He has yet to live up to his draft hype, but in the minors from 2022 to 2024, he posted a 3.77 ERA with 378 strikeouts in 320 innings, quickly advancing to Triple-A.

Black, once seen as a top prospect, made his MLB debut on May 6, 2024. He pitched 14 1/3 innings before being sent down, then was later recalled to throw a first-season total of 36 1/3 innings, posting a 31:15 strikeout-to-walk ratio but allowing a .309 opponent batting average. This season, he pitched just four innings with a 6.75 ERA.

Added to the Royals' 40-man roster, Black still has one remaining option year. The Royals can keep him in Triple-A Omaha, giving him time to work out his kinks. A new location may help the 25-year-old return to the strong production he showed early in his minor league career. The Royals might also test how Black performs in a relief role. Regardless, they paid a minimal price for a pitcher with MLB experience.
