The Baltimore Orioles are exploring options to strengthen their rotation as they aim to contend in the American League and make a serious push for a World Series title. While veteran additions have provided consistency and leadership, the team needs a top-tier pitcher to solidify its rotation. Reports indicate that the Orioles have engaged in discussions with the Seattle Mariners about acquiring star right-hander Luis Castillo. If successful, Castillo would join Grayson Rodriguez and Kyle Bradish, the latter returning from Tommy John surgery, to form a formidable rotation. However, securing Castillo is far from guaranteed.
Seattle, looking to remain competitive in 2025, is expected to demand major-league-ready talent rather than a package of prospects. Baltimore is unlikely to part with Jackson Holliday, Colton Cowser, or Jordan Westburg, as they are considered cornerstone players for the team’s future. Holliday, despite a challenging start in the majors, remains a highly valued former top prospect. Cowser was the AL Rookie of the Year runner-up, and Westburg earned his first All-Star nod last season. None of the trio are on the trading block.
Heston Kjerstad and Coby Mayo, however, present a more complex dilemma. Both are projected to play key roles in Baltimore’s plans—Kjerstad as a fourth outfielder and designated hitter, and Mayo as a potential replacement for Ryan Mountcastle at first base. While both have shown promise in the minors, their major-league performances have been less consistent, raising questions about their ability to reach their full potential.
Castillo, with a career ERA+ of 120 and three strong seasons in Seattle, offers proven value. Orioles GM Mike Elias must decide if trading Kjerstad or Mayo for an ace is worth the risk. Without a frontline starter like Castillo, Baltimore could face challenges throughout the season and in the playoffs. It’s a tough call, but one critical for the team’s success.
