Austin Cox: Everything you need to know

Atlanta outrighted Cox to Triple-A Gwinnett on Thursday. Cox made 13 appearances for Atlanta in 2025, posting an 8.86 ERA and 22:7 K:BB over 21.1 innings. The lefty reliever is no longer on the 40-man roster but remains in the organization.

Atlanta optioned Cox to Triple-A Gwinnett on Friday. Cox was hammered for seven runs in a three-inning relief appearance Thursday in Philadelphia, throwing 68 pitches. He wasn't going to be available to pitch for a few days, so Atlanta is replacing him with a fresh bullpen arm.

Cox allowed one run on three hits while retiring one batter (on a strikeout) Saturday against the Reds before the game was suspended due to inclement weather. Cox was pressed into starting duties after Spencer Strider was scratched due to a weather delay that lasted well over an hour. Cox tossed 17 pitches in the rain in the first frame before the game was halted and ultimately suspended. Atlanta reportedly was set for a bullpen game, so Cox's outing wasn't likely to last much longer even if the contest had continued. The matchup is scheduled to resume Sunday afternoon and Cox is eligible to return to the mound, but it's unlikely Atlanta will send him back out.
