Arizona Diamondbacks third base prospect Deyvison De Los Santos was snatched by the Guardians in December's Rule 5 draft but returned to Arizona this spring. He has seen his prospect stock drop lately (he was MLB Pipeline's No. 5 Diamondbacks prospect in 2023; he opens 2024 at No. 14) but still continues to flash significant upside in the field and at the plate. The 20-year-old converts excellent bat speed into plenty of power, and he's done a good job keeping his strikeout rate somewhat in check so far this season. In the field, he has a slightly erratic glove and arm at the hot corner, suggesting he's destined for first base or designated hitter long-term. Last week, De Los Santos did what he does best: turn heads with a big showing at the plate. The Dominican Republic native went 13-for-24 over the six-game span, adding three homers, nine RBI, two walks, and three strikeouts. He's been in Double-A ever since September 2022 but could secure a much-deserved promotion if he continues to hit the ball well.

Arizona Diamondbacks corner infield prospect Deyvison De Los Santos went 4-for-5 with six RBI and a pair of two-run homers for Double-A Amarillo on Sunday. De Los Santos has been on fire to open the season and is now hitting a shiny .395 with seven home runs and 18 RBI in just 81 at-bats. The 20-year-old out of the Dominican Republic is too aggressive at the plate, but he counters that with top of the class exit velocities and raw power. De Los Santos spent all of 2023 in Double-A, so it would seem to reason that a promotion to Triple-A could be coming with his dominance of Double-A pitching now. It would be nice to see more plate discipline, but De Los Santos is worth rostering in dynasty leagues and would be an exciting speculative add if the Diamondbacks call his name in 2024.
