Jonathan Lucroy drove in Matt Chapman with a two-out, walk-off single in the 11th inning Friday night, allowing the Oakland Athletics to overcome a rare blown save by closer Blake Treinen to defeat the San Francisco Giants 4-3 in Oakland, Calif. The win was Oakland's third in five consecutive games against the Giants, clinching no worse than a tie in the annual Bay Bridge Series that concludes Sunday. After having blown a 3-2 lead with two outs in the ninth, the A's strung together three consecutive singles with two outs off the Giants' seventh pitcher, left-hander Will Smith (0-1), in the 11th.
