Royals Add Mason Black From Giants
The Giants designated righthander Mason Black for assignment on Nov. 6. On Tuesday, they dealt him to Kansas City in exchange for righthander Logan Martin, who just completed his season with the Surprise Saguaros in the Arizona Fall League. Black ranked among the Giants’ Top 10 prospects in each of the last three seasons and made his big league debut on May 6, 2024 and made 10 appearances (including eight starts) over the last two seasons. Martin never cracked the Royals’ Top 30. He went 8-4, 3.45 in in 2025 at High-A Quad Cities.
