Report: Diamondbacks Place Corbin Burnes on 15-Day IL

Burnes had an MRI on Monday, but initial results were not conclusive. Gambadoro reports that the righty will get a second opinion, and more information will likely be known Thursday or Friday.

Burnes had been in the midst of an excellent stretch of pitching, delivering four straight Quality Starts in May and pitching through seven innings in three of those four outings, lowering his ERA to 2.66.

Much had been speculated about Nelson's role prior to this news. The talented young right-hander was one of the D-backs' best starting arms in 2024, and has pitched to a sturdy 3.43 ERA and 3.27 FIP in 2025, working as a starter, long reliever and short reliever.

After making two starts in place of the injured Eduardo Rodríguez, Nelson was told he would be going back to the bullpen on May 31. But with the injury to Burnes, he'll go back to serving as a starter.

With Nelson re-entering the rotation, Henry will take his place to fill a long relief role. Henry has been used in a bullpen role with the D-backs before, including one scoreless 2.2-inning appearance on May 5.

Since then, Henry has worked solely as a starter for Triple-A Reno, pitching to an ugly 7.39 ERA and a 2-5 record in 10 starts. His last two starts, however, have been six-inning Quality Starts, each accompanied by six punchouts.
