2025 Fantasy Outlook
Black went from being a top 15 prospect in the San Francisco organization to being designated for assignment and eventually traded to Kansas City in 2025. Black made just one appearance with the Giants big league club in 2025 allowing 5 runs in a start just before the break. He spent the rest of the season in Triple-A where he struck out nearly a batter an inning, but struggled with too many walks and homers in an unforgiving Pacific Coast League. Black might find more success in the Kansas City pen as a long man or working in Omaha in a role similar to the one Noah Cameron had to start 2025. He might be best working in long relief as his overall stuff is fringy for a starter, but Kansas City seems to get the most out of these types year in and year out. After all, that Bubic breakout came out of left field so at least mull that over if Black is available in AL-Only reserves or in the latter rounds of the draft-and-hold leagues. Read Past Outlooks
