Get to know the 2021 Diamondbacks’ Opening Day roster

Apr 1, 2021, 9:15 AM

The Arizona Diamondbacks on Thursday pushed through transactions to effectively set the Opening Day roster for the 2021 debut in San Diego against the Padres.

Along with setting a 26-man roster by calling up right-handed pitcher Riley Smith from Triple-A, the team also placed starting pitcher Zac Gallen on the 10-day injured list due to a hairline fracture in his lateral forearm near his right elbow. Gallen was in the running to become the team’s ace, and with his injury, veteran Madison Bumgarner will take the mound Thursday.

The Diamondbacks on Thursday also placed outfielder Kole Calhoun (knee) on the 10-day injured list. Reliever Tyler Clippard (shoulder) had previously been added to the IL.

Clippard could miss a month or more, while Calhoun has begun ramping up activities after undergoing surgery on March 3 for a medial meniscus tear.

Here’s a look at the full 26-man roster by position group:
