BALTIMORE — The Oakland Athletics couldn’t get more than one hit in any inning against Baltimore, and many of their hard-hit balls went directly into the glove of one of the Orioles.

The result was a hauntingly familiar 4-0 defeat Tuesday night that extended the A’s losing streak to a season-high eight games.

“It seems like it’s been happening like that all year, especially the last couple of weeks,” Oakland center fielder Ryan Sweeney lamented. “We’re having good at bats but can’t put anything together and hit it right at somebody.”

Chris Jakubauskas pitched five innings of three-hit ball and the Orioles hit three solo homers to move into position to complete a three-game sweep Wednesday. Baltimore had lost eight straight series to Oakland since July 2007.

Jakubauskas (1-0) came into the game with a 6.39 ERA over five appearances, all in relief. He was pressed into duty because the Orioles are carrying only four starters and were playing for a fifth straight day.

Operating against Oakland’s anemic offense, Jakubauskas looked like the ace of the Baltimore staff. The A’s, who have averaged three runs per game while batting .217 during their eight-game skid, absorbed their seventh shutout loss of the season.

“We didn’t hit the ball extremely well, but when we did it was definitely right at somebody,” Oakland manager Bob Geren said. “They had some homers and we couldn’t link any hits together. Made plays defensively, but nothing on the scoreboard.”

The last time Jakubauskas started a game was on April 24, 2010, with the Pittsburgh Pirates. In that game, the right-hander was struck in the head by a liner off the bat of Lance Berkman in the first inning and carted off the field.

Against Oakland, Jakubauskas had a two-hit shutout in the fifth inning when Cliff Pennington smacked a line drive that hit the pitcher above his left ankle.

“There were some choice words that went through my mind after it happened, but I try to keep those as quiet as I could,” Jakubauskas said. “It was more of just, ’I can’t believe this. Really? Again I get hit?”’

After consulting with trainer Richie Bancells and manager Buck Showalter, Jakubauskas took a few warmup tosses and finished his outing by retiring Jemile Weeks for the third out.

It was enough to get him his first win in the majors since 2009 with Seattle.

J.J. Hardy and Luke Scott connected against Guillermo Moscoso (2-2), and Adam Jones made it 3-0 in the sixth with a drive off Michael Wuertz. Mark Reynolds added an RBI double in the seventh against Craig Breslow.

The eight-game slide is Oakland’s longest since an identical skid from Sept. 27, 2009, to April 5, 2010. The A’s are 5-15 since May 17.

Making his major league debut, Weeks went 0 for 4 in the leadoff spot. Weeks, the 12th overall pick in the 2008 draft, had his contract purchased from Triple-A Sacramento before the game. The second baseman is the younger brother of Milwaukee Brewers second baseman Rickie Weeks.

After Jakubauskas left, Clay Rapada retired two batters in the sixth, Jeremy Accardo worked 2 1-3 innings and Koji Uehara got the final three outs to complete the five-hitter.

Batting at the top of the order for the first time this season, Hardy hit his first career leadoff homer, a drive to left that provided Baltimore with a lead it would not relinquish.

Scott hit his seventh homer of the season — the first since May 3 — leading off the fifth. The drive traveled an estimated 418 feet and landed on Eutaw Street beyond the 25-foot wall in right field.

Moscoso allowed two runs and five hits in five innings. Coming into the game, he had not given up a home run this season over 14 innings.

“I missed two pitches and I paid for it,” he said.

“He threw great tonight,” Sweeney said. “We just didn’t score any runs for him.”

Notes: The A’s placed LHP Brett Anderson (sore elbow) and 2B Mark Ellis (strained right hamstring) on the 15-day disabled list. … Actor Ed Harris threw out the ceremonial first pitch. … Eight of Baltimore’s last 10 home runs have been solo shots.

BALTIMORE (AP) — The Oakland Athletics placed left-hander Brett Anderson and second baseman Mark Ellis on the 15-day disabled list Tuesday.

Anderson has a sore left elbow and Ellis strained his right hamstring Monday night against Baltimore. With Ellis out, the A’s selected the contract of former top draft choice Jemile Weeks from Triple-A Sacramento.

Weeks, the 12th overall pick in the 2008 draft, was poised to make his major league debut Tuesday night against the Orioles as Oakland’s leadoff hitter and second baseman.

“I’m not sure what it’s going to be like up here,” Weeks said before batting practice. “Got a little bit of nerves in me right now, but that’s expected. Just hope to be out there and be able to calm down a little bit before the game starts.”

Weeks said he expected his mother, father, sister and agent to be in attendance.

The make room for Weeks on the 40-man roster, Oakland moved pitcher Dallas Braden from the 15-day DL to the 60-day DL.

The A’s also recalled left-hander Bobby Cramer from Sacramento. It’s his third stint with Oakland this season.

“It’s just part of baseball. It’s a long season,” Cramer said.

Anderson is 3-6 with a 4.00 ERA and was coming off successive poor starts against the New York Yankees and Boston Red Sox. He was sent home to Oakland on Monday and is scheduled to see the team orthopedist this week.

Ellis was batting .213 with one homer and 15 RBIs in 58 games. He missed a month last year with an injured left hamstring, but said this injury was not as serious.

“This is not even close to being the same thing,” Ellis said, adding that he expected to return after 15 days.

OAKLAND, Calif. — The Oakland Athletics activated infielder Adam Rosales from the 60-day disabled list Monday and recalled infielder Scott Sizemore from Triple-A Sacramento.Both moves were made before the slumping A’s faced the Baltimore Orioles.To make room for Rosales and Sizemore, the A’s optioned third baseman Kevin Kouzmanoff and right-hander Fautino De Los Santos to Sacramento.Also Monday, the Athletics sent left-hander Brett Anderson (3-6) back to Oakland to have his arm examined by team orthopedist Will Workman.Anderson allowed five runs in five innings against Boston on Sunday. In his previous start, he gave up nine earned runs over 5 1-3 innings against the New York Yankees.Manager Bob Geren wouldn’t discuss specifics about Anderson’s arm, or whether he might miss a start.”It’s just an all-around good idea to have him checked out. Nothing real specific,” Geren said.Rosales, who missed all of spring training with a fractured right foot, batted seventh as Oakland’s starting third baseman on Monday night.”Rosales is a good player, an exciting player,” Geren said. “He brings a lot of energy to the team and plays a lot of different positions.”Sizemore was acquired from the Detroit Tigers on May 27 for left-hander David Purcey. He hit .222 with 10 walks in 17 games with Detroit.In nine games with Sacramento, Sizemore hit .267 with 12 walks and 11 runs scored.Kouzmanoff was hitting .221 with four home runs and 17 RBIs in 46 games. He also had nine errors. “I didn’t see it coming,” Kouzmanoff said. “Obviously, as everybody well knows, I started off slow on both sides of the ball, and I did not play to my potential. All I can do is go down and get my work in and get my reps and try to work my way back.”Geren said, “Kouzmanoff has had a rough start for us both offensively and defensively and he hasn’t played up to what he can do. He will go down to Triple-A and work on his game.”De Los Santos joined Oakland on Friday in Boston and made his big league debut Saturday.
