KANSAS CITY, Mo. — Armando Galarraga carried a perfect game into the seventh inning, Miguel Cabrera drove in three runs and the Detroit Tigers beat the Kansas City Royals 7-1 today to complete a three-game sweep.

Galarraga retired the first 18 batters before David DeJesus led off the seventh with a single to right on a full-count pitch. To that point, the 26-year-old rookie right-hander had allowed just two fly balls to the outfield and struck out six.

He wound up allowing a run in the seventh on three singles and a walk, but left the bases loaded. Galarraga (8-4) was replaced by Casey Fossum in the eighth, after lowering his ERA to 3.27 while striking out a career-high seven against just one walk.

The Tigers outscored the Royals 33-6 in the three-game series.

Cabrera drove in three runs with a pair of singles, raising his RBI total to 10 for the three-game series and 71 for the season. Magglio Ordonez added three hits and a couple RBIs, while Placido Polanco had three hits and scored twice.

The Tigers jumped out to a 5-0 lead after three innings off Zack Greinke.

The Royals right-hander gave up five runs on seven hits, while walking two and striking out eight in six innings. Greinke (7-7) is 0-3 in five starts since a June 24 victory over Colorado.

Ordonez singled home Curtis Granderson with the first run. Polanco scored from third while Ordonez was caught in a run down between first and second for the final out of the inning.

Matt Joyce led off the second with a double, moved to third on a wild pitch and scored on Edgar Renertia's single.

The Tigers made it 5-0 in the third with Cabrera's two-run single, scoring Polanco and Carlos Guillen, and Ordonez and Cabrera had run-producing singles in the seventh off Royals reliever Horacio Ramirez.
