All-Star 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 here in more than a month.
