(AP) -- Melky Cabrera homered, doubled and singled while driving in four runs, Bruce Chen allowed one run in seven innings and the Kansas City Royals beat the Baltimore Orioles 9-1 on Thursday.
Cabrera, who also scored three times, hit a solo homer in the eighth off Clay Rapada.
Chen (4-1) gave up his only run in the first and then pitched shutout ball for the next six innings.
The left-hander, who was KC's biggest winner last year, allowed five hits and one run, walking two and striking out five. He has not lost a start in Kauffman Stadium since Aug. 12, 2010, against the Yankees.
Since then, he's 6-0 in nine starts at home.
Chris Tillman (1-3) took the loss, typically getting almost no offensive support. In his last six starts, the Orioles have scored only five runs while he was in the game.
