Junis gave up three more home runs and the Brewers rolled to a 5-1 victory. He now has permitted a Major League-leading 22 home runs.
"Yeah, I mean, I'm giving up a lot of runs on home runs," Junis said. "If I can keep it in the yard, I would have a lot better chance at keeping some runs off the board. But just a couple pitches I'm leaving over the plate are getting handled."
The Royals have lost 18 of their last 21 games, and all three of those wins came as the result of shutouts. Kansas City has scored 43 runs in that 21-game stretch.
"It's not frustration," Royals manager Ned Yost said of the club's rough June. "Well, that's a lie. We're all frustrated. I've never seen anything like it. I've never seen an offensive drought like we've had all month long. It's pretty puzzling. There's no answer for it."
Milwaukee 22-year-old starter Freddy Peralta threw seven scoreless innings of one-hit ball while striking out 10 in his home debut. That one hit was a double in the third inning by Adalberto Mondesi, who also hit his first homer of the season in the eighth.
"He was really good," Yost said of Peralta. "He had a lot of deception. It is hard to explain. He's got a high spin rate, and the ball just kind of jumps on you even though it's 92 mph. Really good curveballs. Commanded it better than I thought he would."
Junis lasted five innings and gave up seven hits and five runs while striking out seven. He left a 3-0 fastball up in the first inning and Christian Yelich belted it the opposite way to left field for a two-run jack. Jesus Aguilar hit a towering solo home run to center field in the third on a 0-1 slider, and Ryan Braun added a two-run shot on a first-pitch slider in the fifth.
"My stuff hasn't been consistent, but tonight I felt a lot better and I still gave up five runs," Junis said. "It's just something you've got to work towards and keep getting better, and hopefully next time I have my slider again and a little bit better fastball control, and then we can keep the runs off the board and give our team a chance to win."
MOMENTS THAT MATTERED Mondesi got hits from both sides of the plate on Tuesday. He ripped a double in the third from the left side off Peralta, and then he smoked a 2-1 sinker from left-hander Dan Jennings to right-center field for his first home run this season. Statcast™ projected it to have traveled 383 feet.
"It was a little sinker running away," Mondesi said of the homer. "I was just trying to stay short to the ball."
