KANSAS CITY, Missouri — There were two things in common with the pitches Johnny Cueto threw to Chris Davis, Manny Machado and Jonathan Schoop: They all began as cutters, and they all ended up as two-run homers.
"It feels a little weird because it doesn't happen to me very often," Cueto said of back-to-back bad starts, which included a loss at Boston in which he allowed a career-high 13 hits.
Cueto (9-9) gave up 10 hits and a walk over five innings against Baltimore.
"I'm not a robot," he said. "Just have to keep working, get ready for the next one."
Steve Pearce made it 7-3 with a solo shot in the eighth for Baltimore. Mike Moustakas kept the Royals close with a two-run homer off Brian Matusz in the bottom half of the inning, but Ryan Flaherty answered with the Orioles' fifth homer leading off the ninth.
Zach Britton got three outs for his 30th save.
Wei-Yin Chen (8-6) allowed three runs for the Orioles while scattering nine hits over six innings. The losing pitcher against the Royals in Game 3 of last year's AL Championship Series, he has now gone seven straight starts without a defeat.
"Every day we come here to the ballpark, all we think about is how to win today's game," Chen said through a translator. "Hopefully we can move up from here."
The Orioles had lost nine straight to the Royals, and appeared to be in trouble again when they failed to score with runners on the corners and nobody out in the second inning.
In the bottom half, Moustakas hit a sacrifice fly and Salvador Perez an RBI double to stake Kansas City to a 2-0 advantage that could have been more substantial. The inning ended when Omar Infante ran past Paulo Orlando on a flyout, resulting in Infante also being called out.
Moments later, the Orioles started to showcase their power.
Baltimore tied the game in the third on Machado's two-run shot, then pulled ahead in the fourth when Schoop clobbered his two-run homer an estimated 427 feet to left field.
Davis, who was in an 0-for-16 slump coming into the game, made it three straight innings with a two-run shot when he went deep in the fifth. The big first baseman's 35th home run of the season sailed into the left-field bullpen and gave Baltimore a 6-2 advantage.
Kansas City clawed back with a run in the sixth when Kendrys Morales hit an RBI single, but Chen calmly retired Moustakas and Perez to prevent more damage.
When the Orioles tacked on a couple more home runs in the final two innings, the Royals were headed to only their third loss in 15 games at Kauffman Stadium.
"You're facing the best team in the American League last year and they've added players to improve on that," Orioles manager Buck Showalter said. "So it's a challenge, but we've got a chance to split against the American League champions tomorrow and move on to Texas."
