Zac Gallen, the veteran right-handed pitcher for the Arizona Diamondbacks, is facing yet another setback as he deals with elbow inflammation, forcing him to miss his scheduled start on Sunday. This development comes as a disappointment, especially considering Gallen's recent struggles on the mound. With a 6.34 ERA across 19 starts this season, Gallen is having his worst year as a big leaguer. What's more concerning is that his xERA, xFIP, and SIERA are all near 5.00, indicating a decline in his overall performance. The 30-year-old pitcher, who has been a consistent presence in the Diamondbacks' rotation, has only managed a 13.9% strikeout rate in 98 innings, a stark contrast to his previous seven MLB seasons where he consistently maintained a strikeout rate above 21%.
One of the most intriguing aspects of Gallen's situation is the decline of his top three pitches. Opponents are hitting .331 with a .545 SLG against his fastball, and his curveball and slider both have a -7 Run Value, per Statcast. This suggests that Gallen's once-effective pitches are now being effectively countered by batters, leading to his poor performance. The fact that he's maintained his normal velocity but still struggled is a testament to the complexity of pitching and the delicate balance between physical prowess and pitch selection.
Gallen's recent struggles are particularly notable given his history. Coming off an uninspiring 2025 campaign, he returned to Arizona on a one-year deal after rejecting the qualifying offer. Despite his best efforts, the results reduced his appeal on the market, and he ultimately signed for the same $22.025MM figure with deferrals. However, this season has been a different story, and the elbow inflammation is yet another hurdle in his path to recovery.
The Diamondbacks have responded to Gallen's injury by recalling lefty Mitch Bratt to start on Sunday. Bratt made a respectable debut, tossing three innings of one-run ball against the Cardinals in late June. With a 2.41 ERA and a 25.2% strikeout rate in 13 starts at Triple-A this year, Bratt is certainly a promising prospect. However, the team's decision to recall him highlights the uncertainty surrounding Gallen's future and the need for depth in the rotation.
In my opinion, the Diamondbacks' situation with Gallen and Bratt raises a deeper question about the balance between veteran experience and young talent. While Gallen's struggles are certainly concerning, the team's decision to turn to Bratt suggests a willingness to embrace the future and develop young pitchers. This raises the question of whether the Diamondbacks are willing to invest in Gallen's long-term health and performance, or if they are simply looking to the future.
From my perspective, the Diamondbacks' situation with Gallen and Bratt is a fascinating example of the challenges faced by MLB teams in managing their rotations. While Gallen's struggles are certainly disappointing, the team's decision to turn to Bratt suggests a commitment to developing young talent. However, the question remains whether the Diamondbacks are willing to invest in Gallen's long-term health and performance, or if they are simply looking to the future. Only time will tell whether this is a temporary setback or a more significant shift in the team's approach to pitching.
