The Arizona Diamondbacks have recently strengthened their pitching roster by signing Dennis Santana, an experienced right-handed relief pitcher, to a minor league contract. This move addresses the team's need for bullpen depth, particularly after the trade deadline passed without any significant pitching additions. Santana's arrival is anticipated to provide valuable support to the Diamondbacks' relief squad.
Diamondbacks Acquire Dennis Santana to Bolster Bullpen Stability
In a strategic move to fortify their pitching relief, the Arizona Diamondbacks announced the signing of veteran right-handed pitcher Dennis Santana to a minor league contract on Friday, August 7, 2026. This acquisition comes at a crucial time, following the team's inactivity in bolstering their pitching unit during the recent trade deadline. Santana, aged 30, is expected to bring a wealth of experience and an additional option to the Diamondbacks' bullpen.
Santana's professional journey includes stints with both the Pittsburgh Pirates and the New York Yankees. He spent significant time with the Pirates over the past three seasons, having been acquired from the Yankees during the 2024 season. His performance highlights include a 3.89 ERA over 70 innings in 2024 and an impressive career-best 2.18 ERA in 2025. Notably, his 2024 season with Pittsburgh featured a 2.44 ERA and a 29.1% strikeout rate across 39 appearances. The 2025 season also saw him record 16 saves, a personal best. However, his role as closer for the Pirates in 2026 was short-lived, with a 2-for-4 save conversion rate before Gregory Soto took over. Following a challenging May where he posted a 7.45 ERA, Santana moved into lower-leverage situations. He was eventually designated for assignment by the Pirates in late July after the team acquired Ron Marinaccio from the San Diego Padres, leading to Santana's decision to enter free agency.
Despite his past successes, Santana's 2026 season has seen a decline in performance, marked by a 6.05 ERA over 41 2/3 innings, an expected ERA of 5.41, and an FIP of 5.47. His strikeout rate decreased to 19.9%, while his walk rate rose to 11.3%. He also surrendered eight home runs, a notable increase from the five allowed throughout the entire 2025 season. His fastball velocity averaged a career-low 94.1 mph this season, and his slider velocity also decreased to 85.6 mph. Despite these metrics, his slider still maintained a respectable 37.6% whiff rate.
The Diamondbacks' bullpen has faced its share of challenges. Paul Sewald was recently removed from his closer role after blowing three saves in late July, accumulating a 6.23 ERA in 39 innings. Conversely, Brandyn Garcia has emerged as a promising late-inning option, boasting a 2.03 ERA and a 31% strikeout rate across 37 appearances. Meanwhile, Justin Martinez has begun a rehabilitation assignment following elbow surgery, and Ryan Thompson was placed on the 15-day injured list due to a lower back injury, with Philip Abner taking his spot on the roster. The addition of Santana is poised to provide much-needed depth and experience to the team's minor league bullpen, offering him an opportunity to work his way back to the major leagues.
The acquisition of Dennis Santana by the Arizona Diamondbacks highlights the persistent challenges and strategic decisions teams face in maintaining a competitive bullpen. While Santana's recent performance has been inconsistent, his past successes demonstrate a clear potential for impact. This move underscores the importance of depth in professional baseball and provides Santana a valuable chance to revitalize his career. It serves as a reminder that even seasoned players can find new opportunities to contribute and overcome setbacks, ultimately benefiting both the player and the team's long-term aspirations for a more robust pitching staff.
