Zac Gallen's recent elbow inflammation has once again cast a shadow over his promising career. The 30-year-old right-hander, who has been a consistent presence in the Arizona Diamondbacks' rotation, is now facing a challenging season. With a 6.34 ERA across 19 starts, Gallen is experiencing his worst performance as a big leaguer. This decline is evident in his xERA, xFIP, and SIERA, all of which are near 5.00, a stark contrast to his previous seasons. The once-dominant Gallen, known for his high strikeout rate, is now struggling to maintain his velocity and top pitches, with opponents hitting .331 against his fastball and his curveball and slider both having a -7 Run Value.
Gallen's recent free agency journey adds another layer of complexity to his situation. After rejecting a qualifying offer, he signed a one-year deal with the Diamondbacks, returning to the team he had been with since his MLB debut. This decision, coupled with his current struggles, raises questions about his long-term prospects. The fact that he is dealing with elbow inflammation, which could require an IL stint, further emphasizes the challenges he faces.
The Diamondbacks have responded by recalling left-hander Mitch Bratt, who made a respectable debut in late June. Bratt's performance in Triple-A, with a 2.41 ERA and a 25.2% strikeout rate, suggests he could be a valuable addition to the rotation. However, the team's decision to rely on Bratt instead of Gallen highlights the level of concern surrounding the veteran pitcher's health and performance.
Gallen's situation is a stark reminder of the delicate balance between talent and health in professional sports. While he has avoided significant injuries in the past, the current elbow inflammation could be a sign of underlying issues. As he deals with this setback, the Diamondbacks must carefully consider their options, both for the remainder of the season and beyond. The team's decision-making will be crucial in determining Gallen's future and the overall success of the organization.
