McGough was optioned to Triple-A Reno on Tuesday.
McGough's demotion creates room for Paul Sewald's reinstatement from the 15-day IL. McGough has endured a rocky 2024 campaign, falling to a 6.75 ERA and a 10:10 K:BB ratio over 16 innings (15 appearances) with a 1-3 record and a pair of blown saves. He'll look to get back on track with Reno.
