On Thursday evening, the Miami Marlins and Arizona Diamondbacks agreed to a trade exchanging left-handed reliever A.J. Puk for corner infielder Deyvison De Los Santos and outfielder Andrew Pintar. De Los Santos would have ranked eighth and Pintar would have ranked 21st on Baseball America's upcoming D-backs Top 30 prospects list. The deal is official.
Puk, 29, began the season as a starting pitcher for the Marlins. When that experiment failed, he went back to being a reliever and has been dominant, posting a 2.08 ERA and a 2.42 FIP. Currently, Puk is riding a streak of 16 ⅔ innings (14 appearances) without allowing an earned run. The Diamondbacks will have him under club control for two additional seasons via arbitration, which played a major role in the quality of the prospects coming to Miami.
The main piece of the package is Deyvison De Los Santos. Between Double-A and Triple-A, De Los Santos has slashed .325/.376/.635/1.011 this season with 28 home runs (most in Minor League Baseball) and 84 RBIs. He has homered 14 times at each level while being among the youngest players in those leagues. De Los Santos just turned 21 in June.
The Cleveland Guardians selected De Los Santos in the Rule 5 Draft last offseason, but returned him to Arizona. He isn't currently on the 40-man roster.
De Los Santos' offensive profile is power over hit, showing a maximum exit velocity of 116.0 mph. Despite his excellent 2024 production, there are concerns about his low walk rate and high groundball rate. He's likely to report to AAA-Jacksonville.
Along with De Los Santos, the Marlins acquired Andrew Pintar. At 23 years old, Pintar has seen action primarily at High-A where he's slashed .304/.403/.516/.919 with nine home runs, 32 RBIs and a 160 wRC+. He recently earned the promotion to AA where he's struggled through ten games (.184/.289/.234/.526). Overall, he has stolen 19 bases in 20 attempts.
Defensively, Pintar has split time between the outfield and middle infield positions during his career. He will likely report to Pensacola, a very pitcher-friendly environment, and will be challenged more than he was with the Diamondbacks.
This trade is the first deadline deal completed between the Marlins and Diamondbacks since 2020 when the Marlins acquired Starling Marte in exchange for Caleb Smith, Humberto Mejía and Julio Frias. The year before that, they famously swapped Jazz Chisholm Jr. for Zac Gallen.
The 2024 deadline is on July 30. Expect the Marlins to swing a couple more deals by then.
Will the Marlins finish with a better record in 2026 than they did in 2025?
