Arizona Diamondbacks third base prospect Deyvison De Los Santos was promoted to Triple-A Reno on Tuesday, May 21. The number 14 prospect in the Arizona pipeline has been off to a scorching start of the season at the plate with Double-A and was rewarded for this by moving up to the final stop in the minor leagues. Through 38 games this season with Double-A Amarillo, the 20-year-old posted an incredible .372/.426/.696 slash line with 14 home runs, 37 RBI, and a 12:36 BB:K ratio. De Los Santos spent all of last season with Double-A but posted a mediocre .254/.297/.431 line with 20 home runs. This recent promotion now opens the door for a late-season major league debut, especially due to his impressive start. The 20-year-old should be rostered in most dynasty leagues and could become a popular stash candidate if he can carry this momentum into his taste of Triple-A.

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.
