The name Luis Castillo has surfaced again in Major League Baseball headlines, but not for the three-time All-Star. Instead, it's the right-hander who made a recent journey from the Seattle Mariners to the Baltimore Orioles. For baseball fans following his career, this move marks another chapter in Castillo’s resilient pursuit of a lasting MLB role.

A Fresh Start in Baltimore

Luis Castillo began the 2025 season with the Mariners, securing a minor league contract before working his way up to the MLB roster. He was given opportunities to start in early April, making two appearances in the rotation. Though his outings featured moments of promise, Castillo posted a 7.71 ERA across those starts. Despite limited success, his performance was enough for teams needing pitching depth to take notice.

After Seattle designated Castillo for assignment to make room for outfielder Leody Taveras, Baltimore saw an opportunity and acquired Luis Castillo in exchange for cash considerations. According to MLB Trade Rumors, Castillo was immediately optioned to Triple-A Norfolk as the Orioles adjusted their pitching staff. This minor move might seem small, but it could help Castillo find his groove in a new environment.

A Path Carved Across Leagues and Continents

Castillo's journey to the Orioles is both unique and inspiring. Originally from the Dominican Republic, he first signed as a minor league free agent with the Detroit Tigers in 2022. Castillo saw some major league innings that year before being outrighted to Triple-A. Undeterred, he broadened his experience by pitching in Japan’s Nippon Professional Baseball league, suiting up for both the Chiba Lotte Marines and Orix Buffaloes.

The international experience paid off. Castillo posted a 2.96 ERA during his time in Japan, proving he could adapt and compete in different baseball cultures. When the Mariners brought him back to the U.S., Castillo again showed resilience by competing for a roster spot and eventually drawing attention from Baltimore.

What Luis Castillo Brings to the Orioles

The Orioles are not new to creative roster moves, especially when it comes to pitching. Now, with Luis Castillo joining their Triple-A roster, they are investing in a depth starter with a diverse background. His track record shows solid command when he's on, sitting around the low-90s with his fastballs. His ability to adapt, with major league and NPB experience, makes him a valuable insurance option.

While Castillo does not have overpowering stuff, he offers flexibility and grit—the traits every team wants in a depth pitcher. Baltimore's decision to option him to Norfolk gives them a chance to evaluate him further before making any additional roster moves.
