(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.

The Athletics' ninth straight win was far overshadowed by what erupted in the seventh inning at the Coliseum. Astros catcher Dustin Garneau tackled Laureano before the As outfielder reached Cintron, and a wild scene ensued. A's and Astros players who were sitting in the seats, observing COVID-19 social-distancing protocols, also rushed onto the field. The Astros have won the past three division crowns, a World Series in 2017 and AL pennant last year.

Volquez retired Robbie Grossman on a popup before Piscotty hit a first-pitch drive over the wall in center to match the opening night 10th-inning slam by Matt Olson against the Angels. The 22-year-old lefty was the youngest As pitcher to start a game since Brett Anderson in 2010 and lived up to the hype. He overpowered the Rangers at times, striking out Joey Gallo on a 96 mph to end the first.
