2025 Fantasy Outlook
Few big-league clubs would give De Los Santos a long look as a regular due to his flawed approach and poor defense, but the Marlins only have a few credible candidates to hit 20-plus home runs, so he's in the right place. In the lead up to the trade deadline, Miami dealt A.J. Puk to Arizona for De Los Santos and a lesser prospect (Andrew Pintar), so they accepted him as the headliner for a real player and must like him to some extent. De Los Santos has always had prodigious power relative to most of his peers, and he logged a strong 32.7 percent hard-hit rate and 40 homers in 137 games split between Double-A Amarillo (an extremely hitter-friendly home park) and Arizona and Miami's Triple-A affiliates, including 49 games for Reno in the Pacific Coast League. Bandboxes aside, 40 homers for any minor leaguer is an impressive total. However, De Los Santos is a free swinger (108:22 K:BB at Triple-A), and he slashed .240/.284/.459 with a 28.4 percent strikeout rate and 5.2 percent walk rate after getting dealt out of the PCL and into the still favorable, but less cartoonish, International League. De Los Santos will get to play regularly at first base or designated hitter, and he should provide more power and a worse batting average and on-base percentage than most rookies. Read Past Outlooks

De Los Santos seems likely to begin the season with Triple-A Jacksonville, Barry Jackson of the Miami Herald reports.
ANALYSIS
Acquired from the Diamondbacks in the A.J. Puk trade, the 21-year-old led the minors in home runs last season with 40 over 137 games split between Double-A and Triple-A, and he could provide a power-starved Marlins lineup with a legitimate long-ball threat if he can win a starting job in spring training. De Los Santos also struck out 144 times in those 137 contests while only drawing 33 walks, however, and Miami may want him to prove his plate discipline has taken a step forward before beginning his big-league service clock. Defensively, De Los Santos will likely be limited to DH in the majors, although he did play 108 games at first base in 2024.

Past Fantasy Outlooks
2024
2023
De Los Santos has been mediocre in 123 games at Double-A (.253/.300/.426) while being extremely young for the level. The power-hitting corner infielder generates impressive exit velocities and hit 20 homers in 113 games last season, but his 0.20 BB/K portends significant struggles at the highest level. His readiness will be tested after Cleveland selected him in the Rule 5 draft and stole him from Arizona, at least for now. If he does not look capable in spring training of providing any value at the big-league level, the Guardians would likely return him to Arizona, but they may be able to find a short-side platoon role for De Los Santos in 2024, and if they keep him on the active roster all season they can send him back to the minors in 2025. In addition to an over-aggressive approach, De Los Santos has been a notoriously poor defender to date, which is partly why Arizona didn't protect him from the Rule 5 draft. He doesn't turn 21 until June and would likely be limited to designated hitter and some first base work if he spends the year on Cleveland's active roster.
The pros and cons with De Los Santos are pretty straightforward. Nobody his age can hit the ball harder, and few players his age (doesn't turn 20 until June) have played at Double-A or the Arizona Fall League. On the flip side, he might be on track to be a shorter (6-foot-1) Miguel Sano. Defensively, De Los Santos is limited to being a bad first baseman or a designated hitter. His pitch recognition is poor and ability to make contact is fringe-average. If he is given a pitch to drive, he can hit it a really long way, but pitchers with craft and an ability to command offspeed pitches will eat him up. There's a decent case to be made for cashing him out in dynasty leagues this offseason, as it's very possible he scuffles in a return trip to Double-A and loses most of his value.

Promotion on horizon?
1BArizona Diamondbacks
July 7, 2024
Diamondbacks GM Mike Hazen said Wednesday that he'll be "looking for opportunities" to call up De Los Santos if his "defense comes along," reports Alex Weiner of ArizonaSports.com.
ANALYSIS
The 21-year-old was selected by Cleveland in the Rule 5 Draft during the offseason but was returned to Arizona at the end of spring training. De Los Santos began the campaign with Double-A Amarillo and posted a 1.122 OPS in 38 contests before being promoted to Triple-A Reno. He has continued to hit well for Reno with 12 homers and a .296/.339/.611 slash line in 41 games, but his poor defense remains a point of concern. The Diamondbacks don't have a clear opening at designated hitter with Joc Pederson still hitting well against right-handed pitching, and De Los Santos may have trouble forcing his way onto the big-league roster as a bench piece that's a defensive liability.
