The Miami Marlins promoted first baseman Deyvison De Los Santos to the major leagues for his MLB debut.
De Los Santos was acquired from the Arizona Diamondbacks in the A.J. Puk deadline deal in 2024. Miami added him to the 40-man roster that offseason to keep him out of the Rule 5 draft. The Guardians had previously selected De Los Santos from the Arizona system in a prior Rule 5 draft, but he had a difficult spring and was returned to the Diamondbacks at the end of camp.
The 22-year-old got off to a strong start in the 2024 season, connecting on 28 home runs across 87 games before the trade. He finished the 2024 campaign with a .240/.284/.459 slash line over 50 games for Miami's top affiliate. In the 2025 season, De Los Santos posted a .241/.311/.363 slash line with 12 home runs at Triple-A Jacksonville.
