2025 Fantasy Outlook
There was no outlook written for Humberto Castellanos in 2025. Check out the latest news below for more on his current fantasy value.
$Signed a one-year contract with the Diamondbacks in June of 2024.
Outrighted to Triple-A
PArizona Diamondbacks  AAA
August 19, 2024
The Diamondbacks outrighted Castellanos to Triple-A Reno on Friday.
ANALYSIS
As expected, Castellanos cleared waivers after Arizona designated him for assignment Aug. 11. Since he had been previously outrighted, Castellanos could have elected free agency, but he'll instead stick around in the organization with the hope of earning a call-up to Arizona later on this season. Castellanos worked out of the bullpen for his seven appearances with the big club earlier in 2024 but has been a regular member of the rotation at Reno, with whom he's compiled a 4.39 ERA and 1.24 WHIP across 67.2 innings over 15 outings (14 starts).
