OAKLAND, Calif. -- The Baltimore Orioles had lost 16 of their past 19 games at the O.co Coliseum before kicking off a four-game series Thursday night against the Oakland A's.
So much for historical trends.
Jason Hammel pitched six strong innings, Chris Davis blasted his eighth home run, and the Orioles routed the A's 10-2 in an early-season matchup between two of baseball's most surprising teams of 2012.
Coming off a 6-3 homestand, the Orioles ripped 15 hits as they opened an 11-game, three-city, West Coast road trip.
Davis went 2-for-3 with two walks and two RBIs. He launched a solo shot to left off A's starter Jarrod Parker in a two-run sixth inning when Baltimore increased its lead to 6-2.
Davis wasn't Baltimore's only hitting star. Nate McLouth went 2-for-5 with a double, two runs, two RBIs and two stolen bases. Adam Jones went 3-for-5 with a double, two runs and an RBI. Nick Markakis had two hits in four trips, drove in two and scored twice.
Hammel (3-1) held the A's to two runs, both unearned, and three hits over six innings, winning his second straight start. He struck out two and walked two.
Parker (0-4) lasted just 5 1/3 innings and lost his fourth straight game, the longest skid of his young career. He gave up six earned runs on eight hits as his ERA rose from 7.50 to 8.10. Parker, who went 13-8 with a 3.47 ERA as a rookie last year, struck out five and walked three.
Coming off a 1-5 road trip, the A's opened a seven-game homestand with another loss.
NOTES: The A's reinstated 2B Adam Rosales (strained left ribcage muscle) from the 15-day disabled list and optioned INF Andy Parrino to Triple-A Sacramento. Rosales, who had been on the DL since March 26, played three games for Single-A Stockton and three for Triple-A Sacramento on a rehab assignment. He came off the bench and went 1-for-2 Thursday, and he probably will start Friday's game, manager Bob Melvin said. ... CF Yoenis Cespedes (strained left hand muscle) began a rehab assignment Thursday night with Sacramento as the designated hitter, and he went 1-for-4 with an RBI. He's eligible to come off the disabled list Sunday. "If everything goes well the next three days, then we look to activate him Sunday," Melvin said. ... The Orioles recalled LHP Zach Britton from Triple-A Norfolk, where he was 1-0 with a 1.98 ERA in three starts. He'll be available out of the bullpen this series and is a possible option to start Monday at Seattle, manager Buck Showalter said. Britton is 16-14 with a 4.74 ERA in 40 major league games, 39 of them starts. ... Orioles RHP Steve Johnson (strained right lat) gave up six hits and four runs over five innings Wednesday for Norfolk in a rehab start. "He'll make his next start in four days," Showalter said. "So far so good. He feels good physically."
