The Arizona Diamondbacks will promote right-hander Brandon Pfaadt to make his debut on Wednesday.

Pfaadt isn't currently on the team's 40-man roster, which means they'll have to make a roster move to clear a spot for him.

The 24-year-old was a fifth round pick of the club in the 2020 draft. 

At Triple-A Reno, Pfaadt had a 3.91 ERA and 30 strikeouts over 25 1/3 innings.
