Washington Nationals prospect Alejandro Rosario has returned to the mound for the first time in over 600 days following Tommy John surgery, marking a pivotal moment in his recovery. Acquired in last year’s trade that sent MacKenzie Gore to Miami, Rosario was the most intriguing piece of the deal—a high-upside pitcher whose career trajectory had been unpredictable.
Before his injury, he dominated the minors in 2024 with a 2.24 ERA, striking out 129 batters in just 88.1 innings while walking fewer than 4% of hitters, showcasing elite command alongside a fastball averaging 97 mph and a devastating splitter. His stuff and control had earned him top-100 prospect status, though his collegiate struggles at Miami earlier in his career had raised questions about his long-term development.
