Kyle Nelson: Everything you need to know

Atlanta released Nelson on Thursday. Nelson signed a minor-league contract with Atlanta in late February but won't end up sticking around in the organization once the season gets underway. The veteran left-hander will likely seek out a minor-league deal elsewhere with the hope of pitching well enough at the Triple-A level to earn another opportunity in the big leagues. Nelson made three appearances in the majors with Arizona in 2025, giving up two earned runs on one hit and four walks over two innings.

Atlanta signed Nelson to a minor-league contract Feb. 25. Nelson struggled in 2025 in his first season back from thoracic outlet surgery, allowing two runs in two innings with the Diamondbacks and posting a 9.09 ERA in 42 appearances with Triple-A Reno. The 29-year-old will give Atlanta some experienced left-handed relief depth at Triple-A Gwinnett.

Nelson cleared waivers Wednesday and was outrighted to Triple-A Reno, Alex Weiner of ArizonaSports.com reports. Nelson appeared in just three games for the D-backs in 2025, giving up two earned runs over two innings. He didn't find much success in the minor leagues either, posting an 8.83 ERA and 1.64 WHIP across 34.2 frames. His poor performance will now cost him his roster spot as the offseason begins, and it's unknown whether he will exercise his right to elect free agency.
