2026 Fantasy Outlook
De Los Santos is still 22 and is on the Marlins' 40-man roster, but it's tough to envision him providing enough offensive value in the big leagues to make up for his lack of defensive value. The righty-hitting corner infielder was expected to compete for big-league at-bats early last season, but he never forced a promotion from Triple-A and was 15 percent worse (85 wRC+) than the average International League hitter. De Los Santos cut his swing rate from 58.2 percent in 2024 to 51.4 percent in 2025 while upping his contact rate from 66.2 percent to 71 percent, so the Marlins are clearly working with him and getting results. Unfortunately, his groundball rate remains an issue (51.3 percent) and De Los Santos makes so much weak contact that his overall hard-hit rate was middling (43.9 percent) despite the fact he had an elite 118.5 mph maxEV. Given his age, raw power and slowly improving swing decisions, the Marlins figure to give De Los Santos another big-league camp to impress, but he enters 2026 with a chance to make his big-league debut and also a chance to lose his 40-man roster spot before the season is over.

Signed a one-year contract with the Marlins in March of 2026.
Officially promoted
The Marlins recalled De Los Santos from Triple-A Jacksonville on Saturday.
Analysis
With Christopher Morel (oblique) headed for the IL, De Los Santos will come up from the minors for his MLB debut and could take over as Miami's primary first baseman, though the Marlins may also continue to start Connor Norby at first. The 22-year-old De Los Santos slashed .240/.309/.356 with 11 homers, 52 RBI and 53 runs scored with Jacksonville last year but started 2026 on the right track, going 2-for-4 with a homer, three RBI and two runs scored in the Triple-A opener.

Past Fantasy Outlooks
2025
2024
2023
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.

Latest Fantasy Rumors
Promotion on horizon?
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.
