The Kansas City Royals' pitching staff took a hit Tuesday as two-fifths of its starting rotation was placed on the 10-day injured list.
The Royals placed Danny Duffy and Brady Singer on the IL. They were replaced on the active roster by reliever Tyler Zuber and infielder Ryan McBroom, who were recalled from Triple-A Omaha.
Duffy's move is retroactive to July 17, Singer's to July 18.
Duffy, who has been the Royals' best starter when healthy this season, is dealing with a left flexor strain, the same injury that landed him on the IL for more than a month previously in 2021. The left-hander is 4-3 with a 2.51 ERA, 65 strikeouts and a 1.21 WHIP over 61 innings spanning 13 games (12 starts) this season.
Singer, who has right shoulder fatigue, has struggled for most of his sophomore season. He is 3-7 with a 5.13 ERA, 92 strikeouts and a 1.55 WHIP in 19 games (all starts) and 87.2 innings.
Zuber was optioned June 6 to Omaha, where he is 1-1 with a 2.55 ERA and 22 strikeouts in 16 games (17.2 innings) this season. The right-hander was 0-2 with a 6.35 ERA and 16 strikeouts in 20 games (17 innings) with the Royals before his minor league assignment.
McBroom has appeared in five games for the Royals this season but has spent the rest of his time with the Storm Chasers. He is slashing .271/.341/.538 with 18 home runs and 49 RBIs for Omaha in 2021.
Mike Minor will start on the mound for the Royals when they open a two-game series at Milwaukee on Tuesday afternoon. The game was moved from Tuesday night because the Milwaukee Bucks could capture the NBA championship if they beat the visiting Phoenix Suns in Game 6 on Tuesday night. Royals-Brewers coverage begins at 2:30 p.m. on Bally Sports Kansas City.
