The Arizona Diamondbacks are staring down a perfect storm of promise and uncertainty as they prepare for the 2026 MLB season. With ace Adrian Del Castillo sidelined by injury and only one healthy outfielder, the team's rotation and lineup are in flux. Meanwhile, the brutally competitive NL West division poses an additional challenge, leaving the Diamondbacks to navigate a treacherous path to the playoffs.

Why it matters

The Diamondbacks' struggles with injuries and roster holes come at a critical juncture, as the team looks to build on recent progress and compete in the stacked NL West. Their ability to overcome these obstacles will heavily influence their chances of reaching the postseason and potentially making a deep run.

The details

The Diamondbacks' rotation is in disarray after Del Castillo's injury, leaving Merrill Kelly as the lone established starter. Zac Gallen has endorsed Kelly as the Opening Day starter, but the team desperately needs other arms to step up. In the outfield, the loss of Lourdes Gurriel Jr. and Corbin Carroll has left a gaping hole, with Brandon Pfaadt and others vying for playing time. The Diamondbacks also face the daunting task of competing in the NL West, which features several powerhouse teams.

  • Adrian Del Castillo's injury occurred in February 2026, sending ripples through the Diamondbacks' rotation.
  • Lourdes Gurriel Jr. and Corbin Carroll are currently sidelined, leaving the outfield in flux ahead of the 2026 season.
