Diamondbacks Rely on Rotation Depth Amid Uncertainty Over Kelly's MRI Results

D-backs banking on their deep rotation as they navigate uncertainty with Kelly's back issue, highlighting confidence in their pitching arsenal.

**Scottsdale, Ariz. ** - The Diamondbacks are in a bit of a holding pattern as they await the results of an MRI on Merrill Kelly's back.

The right-hander was slated for a live batting practice session on Saturday but felt discomfort in his left-mid back area, prompting the medical check. As of their 10-9 loss to the Angels on Sunday, the results were still pending.

Kelly, who rejoined the Diamondbacks in December with a two-year, $40 million deal after a stint with the Rangers, was named the Opening Day starter by manager Torey Lovullo. Despite the recent setback, Kelly remains cautiously optimistic.

“I don't have a concern level [yet],” he mentioned. “It didn’t rear its head until today, so I’m taking that as a positive.”

The Diamondbacks hope to have more information by Monday. If Kelly does miss time, Arizona is fortunate to have depth in their starting rotation. The recent re-signing of Zac Gallen bolsters a group that includes Ryne Nelson, Eduardo Rodriguez, Brandon Pfaadt, and Mike Soroka, who joined as a free agent during the Winter Meetings.

General Manager Mike Hazen highlighted the significance of Gallen’s return: “Not only do we have a talent like Zac, but it strengthens our rotation overall. Last year, we used a lot of starters, and I expect the same this year.”

Reflecting on last season, the Diamondbacks faced challenges despite a strong rotation lineup. Injuries to players like Jordan Montgomery and Corbin Burnes tested their depth, emphasizing the importance of having a robust pitching staff.

On another front, the Diamondbacks are navigating the use of the Automated Ball-Strike (ABS) system, currently in play during Spring Training and set for the regular season. Manager Torey Lovullo has set early guidelines, preferring only catchers and batters to challenge calls.

“If you're 100 percent certain and you're the catcher or hitter, you can challenge,” Lovullo explained. He emphasized the strategic importance of conserving challenges for later innings, viewing it as a team effort to win innings rather than individual at-bats.

As the Diamondbacks continue their preparations, the focus remains on maintaining a competitive edge while managing the uncertainties that come with the game.
