The Royals announced that they have acquired right-hander Mason Black from the Giants. Minor league righty Logan Martin heads in the other direction. The Giants designated Black for assignment last week. The Royals' 40-man roster count climbs from 36 to 37. Black, 26 next month, joins a new organization for the first time in his career. The Giants took him with a third-round pick in 2021. As he climbed the minor league ladder, he was generally regarded as one of the club's top ten prospects.
Coming into the year, he had actually done well in Double-A at the end of 2024, with a strikeout rate approaching a third of batters faced, and a walk rate just barely above 10 percent. The assumption was probably something like a nice, long look in Spring Training, and then Triple-A to start the year before getting called up after a few months.
Montgomery has returned to form, hitting .276/.382/.586 with a .969 OPS in 16 games since rejoining the Knights, showcasing significant improvement after earlier struggles.
