The Arizona Diamondbacks have made a notable addition to their bullpen by acquiring left-handed reliever A.J. Puk from the Miami Marlins. In exchange, the Marlins will receive promising prospects Deyvison De Los Santos and Andrew Pintar.
Puk's Performance and Role
A.J. Puk began the season in the Marlins' rotation but transitioned back to the bullpen after four starts. As a reliever this year, he has been impressive, posting a 2.08 ERA with 33 strikeouts and six walks over 30 1/3 innings. His performance has earned him an ERA+ of 109 across parts of five big-league seasons. Notably, Puk won't be eligible for free agency until after the 2026 season, making him a valuable long-term asset for the Diamondbacks.
Puk is expected to become the Diamondbacks' primary lefty setup man behind closer Paul Sewald. This role will be crucial as the team looks to bolster their bullpen for a playoff push.
Details of the Prospects
The Marlins, on their end, are acquiring two promising prospects. Deyvison De Los Santos and Andrew Pintar offer potential strengths for Miami’s future lineup.
Deyvison De Los Santos, 21, has showcased his power with 28 home runs in a combined 87 games at the Double- and Triple-A levels this season. His career slash line of .293/.343/.508 over four minor-league seasons highlights his consistent ability to get on base and drive in runs. This season, De Los Santos has been versatile in his defensive assignments, spending time at first base, third base, and as a designated hitter (DH).
Andrew Pintar, 23, a former Brigham Young product, has been solid at the plate with a .266/.355/.413 batting line in two minor-league campaigns. Recently promoted to Double-A, Pintar has predominantly played center field as a pro but has also gained experience in left field and at second base. His versatility and ability to get on base make him a valuable addition to the Marlins’ depth chart.
The Diamondbacks' Standing
Currently holding a 53-50 record, the Diamondbacks are in a competitive race for a playoff spot. They are just one game behind the Padres for the third and final wild-card position in the National League. The race is intense, with nine teams in the NL within 5 1/2 games of the final wild-card berth. Acquiring Puk could provide the bullpen reliability that the Diamondbacks need to secure a playoff position.
This trade marks a strategic move by both teams. The Diamondbacks strengthen their bullpen immediately with an experienced and effective reliever, while the Marlins add potential future stars who could impact their lineup in the years to come. As the season progresses, it will be interesting to see how this trade shapes the playoffs and the futures of the teams involved.
