The Mariners signed Dunning to a minor-league contract Thursday, Chris Cotillo of MassLive.com reports.

Jan 22Rotowire

Dunning had to settle for a minor-league deal after posting a 6.97 ERA and 21:7 K:BB over 20.2 innings between Texas and Atlanta in 2025. The 31-year-old could be useful swingman depth for Seattle at Triple-A Tacoma.

Dunning elected to become a free agent Thursday, David O'Brien of The Athletic reports.

Oct 2Rotowire

After being removed from Atlanta's 40-man roster, Dunning has exercised his right to free agency rather than accepting an outright assignment. The 30-year-old swingman has managed just a 5.60 ERA over 15 starts and 23 relief appearances at the big-league level since 2024.

Dunning cleared waivers Wednesday and was outrighted to Triple-A Gwinnett.

Oct 1Rotowire

Dunning pitched 10 innings for Atlanta after joining the organization in July, during which he surrendered 12 earned runs while striking out 11 batters and walking two. The 30-year-old will have the option to elect free agency, though his recent performance may not attract more than a minor-league contract.

Atlanta optioned Dunning to Triple-A Gwinnett on Friday.

9/19/25Rotowire

Dunning has struggled in a mop-up role with Atlanta, posting a 10.80 ERA over seven appearances. His spot on the roster and in the bullpen will be absorbed by Jhancarlos Lara.

Atlanta recalled Dunning from Triple-A Gwinnett on Monday.

9/8/25Rotowire

Atlanta's bullpen saw heavy use over the previous two days, so Dunning will join the big club to provide a fresh relief arm. He's allowed 13 runs over 17.1 innings covering 10 appearances in the majors between Texas and Atlanta in 2025.
