De Los Santos was somewhat surprisingly given no real shot to win a spot on the Marlins this spring, and he started off slowly in Triple-A, but he’s coming along now; he’s 11-for-25 with five extra-base hits in his last six games, putting him up to .311/.374/.432 overall. He’ll likely earn a look at first base or DH sometime this summer.

De Los Santos, 21, was acquired from the D-Backs in the deal for A.J. Puk last summer. The 21-year-old smashed 40 homers during the 2024 campaign, and while his power potential is significant, there’s a good chance his lack of skills pretty much anywhere else prevents him from being a regular MLB player.

De Los Santos was a Rule 5 Draft pick last year by the Guardians, but he didn’t make the team and was returned to Arizona. He went on to have a strong campaign in the minors with 40 homers, and was traded to Miami for AJ Puk. De Los Santos has flaws, but has enough offensive upside to have some fantasy relevance someday. He could make his debut in 2025.

The biggest question for De Los Santos is whether he’ll make enough contact for his prodigious raw power to play at the highest level. The 21-year-old slugging prospect, who came over from the Diamondbacks at the trade deadline, is going to get a shot in Miami at some point in the near future. He’s a name fantasy managers should have on their radar screens heading into 2025 drafts.
