Rest-of-Season Projections
Signed a one-year, $825,000 contract with the Diamondbacks in January of 2025.
Sent down to Reno
The Diamondbacks optioned Nelson to Triple-A Reno on Wednesday.
Analysis
After giving up two runs in two-plus innings and collecting his first big-league save following his call-up from Reno last Friday, Nelson will return to the minors to open up a spot in the bullpen for Casey Kelly, who was called up from Triple-A. Nelson owns a 6.08 ERA through 23.2 innings in the minors, though the amount of injuries in Arizona's bullpen keeps the door open for him to return to the big club before the end of the season.
