BALTIMORE -- Delmon Young drove in five runs, Chris Davis homered and the Baltimore Orioles received a bounce-back pitching performance from Bud Norris in an 18-7 victory over the Boston Red Sox on Sunday.
Baltimore took control with a six-run third inning and led 12-0 in the sixth. Davis, Jimmy Paredes and Steve Pearce each contributed three RBIs to the Orioles' second straight win following a five-game skid.
It was Baltimore's most prolific offensive showing since an 18-9 win over Cleveland on April 19, 2006, and the most runs the Orioles ever scored against Boston.
Baltimore finished with 20 hits, three apiece by Young, Davis, Paredes and Rey Navarro.
Norris (1-2) allowed three runs and seven hits in 6 2/3 innings. The right-hander came in with a 17.42 ERA after allowing 20 earned runs in his first three starts.
In this one, Norris didn't allow a runner past second base until Pablo Sandoval hit a three-run drive in the seventh, his first home run with Boston since signing as a free agent in November.
Boston starter Wade Miley (1-2) gave up six earned runs and five hits in 2 1/3 innings, the second time in four starts this season the left-hander failed to go three innings.
After scoring an unearned run in the second inning, Baltimore sent 10 batters to the plate in the third.
Miley issued two straight four-pitch walks to force in a run, then gave up an RBI single to Young before Davis hit a liner that glanced off the glove of center fielder Mookie Betts for a two-run double. Pearce chased Miley with a run-scoring bloop single and Paredes capped the uprising with an RBI grounder.
Young singled in two runs in the fourth to make it 9-0. Navarro had an RBI single in the fifth and Davis hit a two-run drive in the sixth.
Boston closed to 12-4 in the seventh, but Baltimore answered with six runs in the bottom half, the key hit a two-run double by Young.
Orioles: SS J.J. Hardy (left shoulder strain) will need only three or four rehabilitation games after he's ready to go on assignment, manager Buck Showalter said.
Red Sox: Boston RHP Joe Kelly (1-0, 4.08 ERA) faces his fourth different AL East foe this season, at home against Toronto on Monday night.
