PHOENIX (AP) - Wade Miley had been on a nice roll lately, winning four of his previous five starts with two scoreless outings.

It ended with a big thud by the suddenly-big bats of the Kansas City Royals.

The Royals hit two of their three homers off Miley and the Arizona left-hander allowed a career-worst 10 runs in the Diamondbacks’ 12-2 loss to the Kansas City on Tuesday night.

“I really sucked,” Miley said. “Games like that really get out of hand. You can’t have that. That one is on me.”

Kansas City have struggled to score runs all season and have been particularly quiet when Danny Duffy has been on the mound.

The Royals broke out in a big way, battering Miley (7-8) for 10 runs by the fifth inning.

Salvador Perez had the first big blow with a three-run homer in the third inning. Billy Butler, who had four hits, added another three-run shot during Kansas City’s eight-run fifth. Aoki capped the big inning with his first career slam, marking the first time the Royals had a grand slam and three-run homer in the same inning.

Kansas City had 10 of its 15 hits - three by Perez - by the fifth inning and had a season-high in runs, allowing Duffy (6-10) to cruise to his first win since June 30.

Not bad for a team that’s missing its best hitter (Eric Hosmer) and entered the game with 62 homers in 110 games, by far the fewest in the majors.

“You score 10 runs off of three swings of the bat, you’ll take it,” Royals manager Ned Yost said. “I’m not really (used to it), but I’ll take it when I can get it.”

The Royals have mostly struggled when Duffy has pitched this season, producing 2.34 runs of support, lowest in the majors among pitchers with at least 100 innings. The left-hander had allowed a run or less in 11 of 16 starts, yet was 4-5 in those, including four straight losses.

That changed in a big way against the Diamondbacks and Miley.

Arizona’s left-hander had been sharp over his previous six starts, going 4-1 with a 2.45 ERA, including 6 2-3 scoreless innings his last outing.

The Royals hit Miley hard early, starting with Perez’s 13th homer in the third inning. Butler added his own three-run shot in the fifth and, after a pair of wild pitches by Miley, Aoki put the capper on the big inning with his first career grand slam on the first pitch by reliever Bo Schultz.

Miley allowed nine hits and walked three.
