Kansas City, MO (Sports Network) - Mike Moustakas' early RBI double proved to be the difference, and Greg Holland dodged a bullet in the ninth, as Kansas City clipped Baltimore, 3-2, in the second test of a four-game series.
Eric Hosmer collected a pair of hits and Chris Getz also drove in a run for the Royals, who have won three of their last five.
Bruce Chen (4-0) scattered three hits and one run with four strikeouts over six innings to remain unblemished in 2013.
Holland picked up his 25th save, but not without some effort. Nick Markakis singled to start and scored on Adam Jones' triple to the gap in left center, but Chris Davis fanned swinging, J.J. Hardy grounded to third and Henry Urrutia grounded to first to end the game.
Manny Machado hit a solo homer for the Orioles, whose five-game win streak came to a halt. Jason Hammel (7-7) was tagged in the loss for 10 hits and three runs, walking four and fanning four over his six-inning outing.
