BALTIMORE, Md. -- Delmon Young had three hits and five RBIs, Bud Norris pitched into the seventh inning and Baltimore Orioles battered the Boston Red Sox 18-7 on Sunday.

First baseman Chris Davis added three hits, including his fourth home run of the season and a two-run double, as the Orioles took the deciding tilt of the three-game series.

Designated hitter Jimmy Paredes tripled, doubled and singled to drive in three runs as part of Baltimore's 20-hit attack.

Norris (1-2), who began the day with a 17.42 ERA, allowed three runs on seven hits over 6 2/3 innings.

Designated hitter Hanley Ramirez drove in four runs with his seventh and eighth home runs of the season, and third baseman Pedro Sandoval added a three-run shot for Boston, which has lost four of five.

Home runs accounted for 14 of Boston's 15 runs in the series.

For the second time in his last three starts, Boston's Wade Miley (1-2) failed to make it out of the third inning. He allowed seven runs -- six earned -- on five hits and two walks over 2 1/3 innings.

He's now walked 11 batters in 15 2/3 innings.

Leading 1-0 after two innings, the Orioles sent 10-men to the plate in the third as they chased Miley.

With runners on first and second and one out, Miley issued back-to-back walks to third baseman Manny Machado and center fielder Adam Jones, forcing in a run.

After Young singled home a run, Davis hit a shot to deep center that a leaping center fielder Mookie Betts couldn't haul in, resulting in a two-run double.

Left fielder Steve Pearce made it 6-0 and ended Miley's afternoon with a bloop a single over the drawn-in infield.

Baltimore went up 9-0 in the fourth when Young's single to left scored Machado and second baseman Rey Navarro.

Navarro (career high three hits) made it 10-0 when he picked up his first career RBI with a fifth-inning single.

Davis's fourth home run came in the sixth and Paredes (7-for-10 over his last two games) added an RBI-triple later in the inning.

After Boston scored four in the top of the seventh, the Orioles added six in the bottom half, two on Young's double.
