OAKLAND, Calif. -- The Baltimore Orioles sure know how spoil a 40th anniversary party.
After the Oakland A's honored their 1973 World Series championship team in a pre-game ceremony and Reggie Jackson threw out the first pitch Saturday, the Orioles took center stage and hammered their way to a 7-3 victory, their third straight win in this four-game series.
Nick Markakis launched a two-run home, and Adam Jones ripped a solo shot in a four-run Orioles rally in the fourth inning. Nate McLouth hit his first home run of the season, a solo shot in a two-run eighth.
The Orioles had lost 16 of their past 19 games in Oakland before beating the A's in three straight. On Sunday, they'll go for their first four-game sweep in Oakland since May 22-25, 1987.
"We have struggled here," Markakis said. "If you look at our record here it's not very good, but it's a good way to start the road trip. Win the first three. We won the series. That's our goal from the start. We'll have to come out tomorrow and win another one."
The only bad news for the Orioles was an injury to backup catcher Taylor Teagarden, who got a rare start. He suffered a dislocated left thumb in the bottom of the fifth inning, taking a hard foul tip, and immediately left the game. Manager Buck Showalter said he won't know how long Teagarden will be out until after the swelling in his thumb goes down.
"It will take a couple of days to look at it and make a decision," Showalter said.
Orioles right-hander Chris Tillman held the A's to two runs on seven hits over six innings, earning his first victory while striking out a season-high seven and walking two. He raised his record to 1-1 and lowered his ERA from 5.23 to 4.73. After giving up a run in the first and one in the second, Tillman settled down.
"I was able to get in a rhythm there later in the game," Tillman said. "I think Teagarden did a great job of getting me back on track. I was able to make some big pitches with my offspeed, which I wasn't able to do early in the game. Got me going."
A's right-hander A.J. Griffin lost his second straight start, the longest skid of his young career. He gave up four runs -- all in the fourth -- on five hits over seven innings. He struck out seven and walked two.
The Orioles and A's kept streaking in opposite directions Saturday. The Orioles won their third straight game and eighth in their past 10. The A's lost their fourth straight and eighth in their past nine.
"We're just pressing right now and trying to do a little too much," A's manager Bob Melvin said.
Not every Athletic is pressing. Third baseman Josh Donaldson had four hits, matching his career high set Aug. 17 against Cleveland. Donaldson went 4-for-4 with two doubles and two RBI, raising his average to .318.
"I feel pretty good," Donaldson said. "I was able to get a couple pitches to hit today. When they gave me the pitches, I was able to put them where they weren't.
"It's still early in the season. I believe I have the capability to (hit over .300). It's just about going out there and being consistent every day. So far everything's been on schedule."
Just as they did Friday night in a 10-2 loss to the Orioles, the A's took an early 2-0 lead and quickly blew it.
Brandon Moss singled and Donaldson doubled him home, giving the A's a 1-0 lead in the bottom of the second inning. Then in the third, Seth Smith lined a one-out single and later scored on Donaldson's single, making it 2-0.
The Orioles answered with four runs in the top of the fourth off Griffin. After Manny Machado worked a leadoff walk, Markakis sent Griffin's 1-2 breaking ball over the right-center wall for a two-run blast, as the Orioles pulled even.
"I was looking for a ball to hit hard, and he left one over the plate," Markakis said. "I put a pretty good swing on it and it went over the fence, so it was good."
Jones lined an 0-1 fastball over the left-center wall for his first career home run in Oakland, putting the Orioles ahead 3-2 and giving him at least one homer in every American League city.
Griffin walked Chris Davis on four pitches. Then, with one out and Davis running on the pitch, J.J. Hardy lined an RBI single to center, giving Baltimore a 4-2 lead.
"It was big," Tillman said of the four-run rally. "They came back and picked me up. I had a rough couple first innings. I knew they were going to put up some runs today. It was just a matter of when. I've just got to get back in the dugout as fast as I can and get those guys up there and get momentum back on our side."
Tillman did what A's pitchers haven't been able to do lately: get a shutdown inning after getting a lead.
Melvin said of Griffin: "He pitched well pretty much every inning but one. When you only score two runs and give up four in one inning, it's going to end up costing you. It shouldn't, one bad inning, but we're not putting enough run across the board to overcome a big inning, and a big inning has been our Achilles' heel here recently."
NOTES: The A's had a large turnout of players from their 1973 team for the festivities. Hall of Famers Jackson and Rollie Fingers, Vida Blue, Joe Rudi, Sal Bando, Billy North, Gene Tenace, John "Blue Moon" Odom, Bert Campaneris, Dick Green and Ray Fosse were among those who took part. Fans received a Jackson bobblehead. "It's nice to be here and put my A's shirt on, wear my As' hat," Jackson said. "I wear my A's hat when I play golf. I work for the Yankees and love the Yankees, but the A's are certainly a part of me that goes back forever." ... A's outfielder Yoenis Cespedes (strained muscle, left hand) is expected to be activated from the disabled list Sunday and be in the lineup against Baltimore, manager Bob Melvin said. "Looks good from everything I heard," Melvin said. The A's have gone 4-9 in the 13 games Cespedes has missed. "He takes pressure off everybody. That's what premier players do," Melvin said. "Even when they're not swinging well, the other team knows where he is all the time. They're always aware of him. Everything around him seems to be a little easier. So we look forward to getting him back." ... The Orioles released veteran right-handed reliever Scott Proctor, who had been pitching for Triple-A Norfolk. He allowed seven earned runs and 10 hits over 7 1/3 innings. After pitching last season in Korea, Proctor signed a minor league deal with the San Francisco Giants. The Orioles acquired him in March from the Giants.
