The 2026 MLB season has finally arrived, with all 30 teams set to kick off their campaigns. The Arizona Diamondbacks are one of the teams facing significant questions, particularly regarding their rotation. The team's pitching staff is a major concern, with several key players struggling to find consistency.
Zac Gallen, who signed a one-year deal, had a disappointing 2025 season and will need to bounce back to prove his worth. Merrill Kelly, 37, is dealing with back issues, while Eduardo Rodriguez's ERA has been above 5 in both seasons with the Diamondbacks. Brandon Pfaadt's 5.25 ERA last season raises concerns about his ability to perform at a higher level. Ryne Nelson showed promise in 2025, but it remains to be seen if he can build on that success and become a true ace. Mike Soroka's inconsistent performances since 2019 also cast a shadow over the team's rotation.
The Diamondbacks' chances of success will largely depend on whether they can get the best versions of Gallen and Kelly, while Nelson continues to improve and Rodriguez returns to his 2023 form. However, with several question marks surrounding the rotation, it's uncertain if the team can put it all together.
The Diamondbacks' starting pitching is likely to be a problem, making it an uphill task for the team to achieve success in the 2026 season.
The Diamondbacks' rotation woes are a major concern, but the emergence of Ryne Nelson as a potential star could be the key to their season. If Nelson can build on his 2025 performances and become a reliable starter, it could give the team a much-needed boost. However, with several question marks surrounding the rotation, it's uncertain if the Diamondbacks can overcome their pitching issues and make a deep run in the playoffs.
