KANSAS CITY, Mo. (AP) -- Ramon Hernandez hit his fifth career grand slam and Steve Trachsel pitched a five-hitter to win his third straight start, leading the Baltimore Orioles over Kansas City 9-1 Monday night and extending the Royals' losing streak to five.

Hernandez's slam off Scott Elarton (1-1) put the Orioles on top 6-0 in the fourth. Kansas City has been outscored 45-11 during its skid and has allowed six slams this season, including two in its last three games.

Trachsel (4-3) took a two-hit shutout into the seventh but surrendered a leadoff double to Mark Grudzielanek, who scored on Mike Sweeney's groundout. Trachsel escaped a bases-loaded jam in the eighth when Mark Teahen flied out.

Trachsel walked three, struck out none and threw 104 pitches in his first complete game since a rain-shortened, four-inning loss for the New York Mets on May 11 last year at Philadelphia. His previous nine-inning complete game was a two-hitter for the Mets against Colorado on Aug. 18. 2003.

Before the winning streak, Trachsel had been 0-2 in his previous four starts.
