In nine straight starts, Miguel Gonzalez had completed six innings, and for the last 11 games, Orioles starters had gone at least six. Both streaks came to an end on Thursday night.
For the second time this season, former Oriole Jeremy Guthrie shut down his old team 7-1 at Kauffman Stadium.
The Orioles lost their third straight after winning five in a row. They enter Friday night’s three-game series with the Boston Red Sox in third place, four games behind the AL East leaders.
Gonzalez (8-4) was touched up by the Royals (47-51) for six runs on eight hits in 4 2/3 innings.
Guthrie (10-7) allowed just one run on six hits in six innings.
Kansas City scored two runs in the first on RBI singles by David Lough and Salvador Perez. Alex Gordon’s sacrifice fly in the second made it 3-0.
The Orioles (57-46) scored their only run off Guthrie in the fifth on a triple by Henry Urrutia, his first extra-base hit, and a double by Brian Roberts.
Nate McLouth followed with a sinking liner to right that was ruled a catch by Gordon, causing a lengthy argument by manager Buck Showalter. That ended the inning.
In the bottom of the fifth, the Royals finished Gonzalez with three runs. Gordon’s RBI triple, Eric Hosmer’s run-scoring single and Lough’s RBI single gave Kansas City a 6-1 lead.
Billy Butler hit his ninth home run of the year in the seventh off Francisco Rodriguez, who was making his Orioles debut.
Aaron Crow, Kelvin Herrera and Louis Coleman each pitched a scoreless inning in relief of Guthrie.
