Oakland right-hander Osvaldo Bido retired the first 14 San Francisco batters in order and carried a no-hit bid into the sixth inning, shutting down the Giants as the Athletics won 2-0 Saturday in the second-to-last game of the Bay Bridge Series. Bido's bid ended when he gave up Grant McCray's one-out infield single in the sixth on which the ball traveled about two feet at 67.3 mph off the bat. The 28-year-old Bido (4-3) did not allow a baserunner until Mike Yastrezemski drew a two-out walk in the fifth inning.
