KANSAS CITY, Mo. -- Bruce Chen and three Kansas City relievers combined for a five-hitter as the Royals beat Baltimore 3-2 on Tuesday night, ending the Orioles' five-game winning streak.
Chen, who was making his second start since replacing Luis Mendoza in the rotation, retired the final 10 hitters he faced after Manny Machado homered in the third for the only Orioles run. Chen allowed just three hits in six innings.
Closer Greg Holland gave up a single to Nick Markakis and an RBI triple to Adam Jones to start the ninth. Holland, however, retired the next three batters to log his 25th save.
Jason Hammel took the loss and is 0-5 with a 5.47 ERA in his past nine starts.
The Royals loaded the bases with no outs in the first on Alex Gordon and Eric Hosmer singles and a Lorenzo Cain walk, but they converted that into just one run when Billy Butler grounded into a double play.
The Royals added another run in the second when Chris Getz's single scored David Lough, who led off the inning with a single and motored to third on Alcides Escobar's single. With runners at second and third and one out, the Royals wasted an opportunity to pad their lead when Gordon struck out and Hosmer lined out to first.
Machado homered with two outs in the top of the third to cut Kansas City's lead to 2-1. Machado took an 0-1 Chen pitch out to left center for his eighth homer of the season.
Mike Moustakas' double in the third scored Cain, hiking the Royals' lead to 3-1. With runners on second and third and none out, Hammel prevented further damage by retiring the next three Royals on three infield outs.
The Royals went 2-for-11 while stranding six runners in scoring position in the first five innings.
NOTES: The Orioles added bullpen depth by acquiring RHP Francisco Rodriguez from Milwaukee, for whom he was 1-1 with 10 saves and a 1.09 ERA. Rodriguez, 31, has 304 career saves. The Orioles sent minor league INF Nick Delmonico to the Brewers. ... Royals RHP Wade Davis, who is 0-4 with a 10.91 ERA in his past four starts, is scheduled to start Saturday at Chicago against the White Sox. Manager Ned Yost made it clear that Davis needs to pitch better to stay in the rotation. "He needs to get it going," Yost said. ... Orioles OF Nolan Reimold underwent season-ending surgery in Clearwater, Fla., to alleviate nerve inflammation in his cervical spine. He was transferred to the 60-day disabled list. It was Reimold's second back surgery in 13 months.
