SAN FRANCISCO (AP) All-Star pitcher Scott Kazmir struck out nine in seven scoreless innings to help the Oakland Athletics win the annual Bay Bridge series by beating the San Francisco Giants 6-1 on Thursday.
Josh Donaldson hit a two-run homer and Stephen Vogt drove in three runs for the A's, who won three of four in the two-city series that began Monday night in Oakland. The A's (58-34) have won seven of eight overall and have matched the best start in Oakland history.
Tim Hudson (7-6) was unable to make it out of the sixth inning and lost his fourth straight decision for the floundering Giants.
San Francisco has lost 15 of its past 19 home games and hasn't won consecutive games at AT&T Park in more than a month.
Kazmir (11-3) allowed three hits and one walk. He has yielded one run or fewer in 11 of 19 starts this season for a 2.38 ERA.
ORIOLES 4, NATIONALS 3
BALTIMORE (AP) - Steve Pearce homered and scored twice to help Wei-Yin Chen earn his team-high ninth victory, and Baltimore beat Washington for its eighth win in 10 games.
Adam Jones and Nelson Cruz both drove in a run for the Orioles, who built a 4-0 lead in the third inning and held on. Baltimore took two of three from the Nationals in this rain-shortened, home-and-home interleague showdown between division leaders.
Jayson Werth homered for Washington and Ryan Zimmerman had two hits and an RBI.
Chen (9-3) gave up three runs in 5 2-3 innings, improving to 6-1 in 12 starts since May 3. He was 0-2 with a 7.71 ERA in his previous two starts against the Nationals.

Gio Gonzalez (6-5) allowed three earned runs and six hits in 6 2-3 innings. His streak of 22 consecutive scoreless innings ended when Pearce connected in the first.
CUBS 6, REDS 4, 12 INNINGS
CINCINNATI (AP) - Luis Valbuena hit a tiebreaking, two-run triple in the 12th inning and Chicago avoided a rare five-game sweep in Cincinnati.
Arismendy Alcantara singled with one out and went to second on Starlin Castro's two-out infield single. Valbuena, who was 0 for 4 with three strikeouts, sent a drive to deep right field against J.J. Hoover (1-6).
Skip Schumaker was unable to catch up with the ball, but Valbuena was thrown out at the plate trying for an inside-the-park home run.
Alcantara got his first major league hit - a two-run double - and drove in three runs. Blake Parker (1-0) pitched the last two innings and the Cubs snapped their losing streak at a season-high six games.
Ryan Ludwick homered, but the Reds couldn't overcome a lineup missing more than half its regulars and the loss of starter Homer Bailey to a knee injury after five innings.
Gold Glove second baseman Brandon Phillips is expected to miss six weeks after having surgery Friday to repair torn ligaments in his left thumb.
PHILLIES 9, BREWERS 1
MILWAUKEE (AP) - Jimmy Rollins broke up Matt Garza's no-hit bid with a single in the seventh before sparking a seven-run outburst an inning later, helping Philadelphia complete a four-game sweep of Milwaukee.
Rollins greeted reliever Will Smith in the eighth by singling to left to drive home two runs. Garza (6-6) had just been pulled from the game to a standing ovation but could only watch from the dugout as his shutout evaporated.
The Phillies sent 12 batters to the plate in the eighth and got RBI ground-rule doubles from Ryan Howard and Cody Asche. Philadelphia swept a four-game series for the first time since taking four in Cincinnati in 2011.
Rookie pitcher David Buchanan (5-5) struck out five in seven innings for the win.
Carlos Gomez homered for the Brewers, clinging to its NL Central lead despite five straight losses and nine in 10 games.
RED SOX 4, WHITE SOX 3, 10 INNINGS
BOSTON (AP) - Mike Carp's pinch-hit single in the 10th inning gave Boston its second straight walk-off victory over Chicago.

David Ortiz had a two-run double for the Red Sox, who ended their 3-7 homestand on an upswing.
Pinch-hitter Daniel Nava drew a leadoff walk in the 10th and scored the winning run for the second consecutive game. Ronald Belisario (3-6) took the loss.

BRAVES 3, METS 1
NEW YORK (AP) - Aaron Harang allowed four hits in seven innings, and Atlanta used early offense against Bartolo Colon to avert a four-game sweep by New York.
The Braves snapped a four-game skid and ended the Mets' season-best, four-game winning streak. New York hasn't swept a four-game set from Atlanta since July 1989.
Freddie Freeman had an RBI double in a two-run first. Harang (9-6) won his fourth straight start, beating the Mets for the second time this season.
Craig Kimbrel worked out of an eighth-inning jam and got four outs for his 28th save in 32 opportunities.

Shelby Miller (7-8) allowed four runs in five innings.
The Cardinals played without All-Star catcher Yadier Molina, who tore a ligament in his right thumb Wednesday. Molina will have surgery Friday and is expected to miss 8 to 12 weeks.
