He appeared in five games for the Phillies and went 2-for-8 with one RBI before the club designated him for assignment and released him on August 17, 2025. His final Philadelphia stint added to a versatile résumé that included outfield play, disciplined at-bats, and the kind of speed that organizations prize in a fourth-outfielder.
After becoming a free agent, Stevenson announced that he would play winter ball for the Tigres del Licey of the Dominican Professional Baseball League, a respected Caribbean circuit that has long served as a platform for players seeking to stay sharp and attract new contracts.
