BALTIMORE — The game was still in the third inning, and Wade Miley was already done pitching after another ineffective start.
On this day, Miley was merely one of several Boston Red Sox hurlers victimized by a seemingly endless barrage of hits by the Orioles.
The Orioles took control with a six-run third inning and led 12-0 in the sixth. Baltimore finished with 20 hits in its most prolific offensive outing since 2006.
Five of Boston's pitchers allowed at least one run, beginning with Miley (1-2), who gave up six earned runs and five hits in 2 1-3 innings. It was the second time in four starts this season the left-hander failed to go three innings.
"It's embarrassing. I know I'm better than this," Miley said. "I'm not even giving us ... a chance at all."
Afterward, manager John Farrell was asked if Miley's spot in the rotation was in jeopardy.
"We just walked off the field," he said. "We haven't discussed that yet."
Farrell said Miley's biggest issue thus far has been allowing a bad situation to get worse.
"He's been the victim of a big inning," the manager said. "Being able to slow it down and minimize the damage in the inning, that's been elusive right now."
Norris (1-2) came in with a 17.42 ERA but 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.
None of that mattered, because the Boston pitching staff had its worst outing since a 20-2 loss at Oakland in August 2012.
"I will say in general, we have to do better in all phases of the game," Farrell said, "and it starts with how the game is controlled from the mound."
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.
Red Sox: Ramirez's next HR will be his 200th ... Miley lost his first April road game in 11 career starts (4-1). ... The Red Sox went 2-4 on a road trip that began in Tampa Bay. They allowed 19 runs in the first five games before surrendering 18 in the finale.
Orioles: Navarro had his first career RBI and his first three-hit game. ... The Orioles have 14 errors in 19 games compared to nine at the same time last year.
Orioles: SS J.J. Hardy (left shoulder strain) will need only three or four rehabilitation games after he's ready to go on assignment, Showalter said.
