(AP Photo/Ben Margot)SAN FRANCISCO Stephen Piscotty hit a tying grand slam in the ninth inning, Mark Canha's sacrifice fly put Oakland on top in the 10th, and the Athletics stunned the San Francisco Giants 8-7 on Friday night in the opener of the Bay Bridge Series. Oakland trailed by five in the ninth inning but rallied to win from such a deficit for the first time since July 15, 1952, according to STATS. The Giants hadn't lost after leading by five or more runs in the ninth inning or latter since June 25, 1929. The ball carried on a rare hot evening in San Francisco, where first-pitch temperature reached 85 degrees.
