Diamondbacks Should Consider Danny Serretti for Future Roster Spot

In a strategic move during the AAA phase of the Rule 5 draft last December, the Diamondbacks selected three players, including infielder Danny Serretti from the Detroit Tigers. While the two pitchers chosen, Antonio Menendez and Sean Harney, have faced their own challenges—Harney sidelined with an undisclosed injury and Menendez struggling after a promotion—Serretti has emerged as a standout in Arizona’s system, warranting closer examination.

Selected by the Tigers in the 6th round of the 2022 draft, Serretti made an immediate impact, transitioning from A ball to AA in just 27 games. His numbers were impressive, boasting a .315 batting average and a remarkable 177 wRC+. However, his journey has not been without hurdles. The following year, he began in High A, where he hit .284 before struggling in AA and continuing to face challenges in his subsequent seasons.

When the Tigers left Serretti unprotected ahead of the 2025 Rule 5 draft, it was a gamble that the Diamondbacks took on a player who had seen his performance dip. Yet, this decision appears to be paying off. Serretti has thrived in Arizona’s minor league system, posting a .283 average with a .447 on-base percentage and a .553 slugging percentage in 53 games at AA Amarillo. His success has continued in AAA Reno, where he is hitting .352 with an impressive .563 slugging percentage.

One of the notable aspects of Serretti’s performance is his ability to dominate left-handed pitching as a right-handed batter. In 102 plate appearances against lefties, he is hitting an impressive .345, compared to a .285 average against right-handers. While some may attribute his success to the hitter-friendly environments of the Texas League and Pacific Coast League, deeper analysis reveals significant improvements in his approach at the plate.

Serretti has increased his walk rate significantly, jumping from 14% to over 20% in AA and maintaining a strong rate in AAA, while also reducing his strikeouts to a more manageable level. This evolution in his game, alongside a marked decrease in pop-up frequency, indicates a refined approach. Additionally, his ability to pull the ball has improved, suggesting a more effective swing mechanics than in previous seasons.

Defensively, Serretti has shown versatility, playing various infield positions and designated hitter during his time in Detroit’s system. In Arizona, however, he has primarily played second and third base, with only limited time at first base. While questions about his arm strength have persisted, he remains a reliable fielder.

As the season draws to a close, the Diamondbacks face a decision regarding Serretti’s future. If they choose to protect him and add him to the 40-man roster, it will signal their belief in his potential as a valuable utility player capable of contributing in a significant way. The upcoming weeks will be crucial in determining how the front office views Serretti’s role within the organization.
