The Kansas City Royals placed right-handed reliever Josh Staumont on the injured list with a neck strain and made several moves to shuffle their bullpen Sunday.

Staumont, in his fourth season with the Royals, posted a 3.81 ERA over 26 innings and recorded three saves. Staumont's stint on the 15-day injured list is retroactive to June 23.

Kansas City also recalled right-handers Matt Peacock and Jackson Kowar from Triple-A Omaha.

Peacock has thrown five and one third scoreless innings over five big league relief appearances for the Royals. In Omaha, he posted a 4.50 ERA across 10 innings.

Kowar has struggled in his first couple tastes of the big leagues; in his sole outing for the Royals against Cleveland on April 10, he was tagged for seven earned runs and 11 hits in 3.1 relief innings. Kowar made nine appearances for Kansas City in 2021, including eight starts, to the tune of an 11.27 ERA. He has a 6.34 ERA across 12 starts at Triple-A Omaha.

Additionally, the Royals optioned left-hander Foster Griffin to Omaha. Griffin, a former first-round pick, surrendered six earned runs over seven relief innings in the bigs. He recorded two outs in a scoreless appearance vs. the Athletics on Saturday, giving up a walk and striking out one batter. Griffin also pitched in Wednesday's 5-0 loss to the Angels, allowing two earned runs in one inning.
