SAN FRANCISCO — Let's all sing it. "Tomorrow ... tomorrow ... will the Giants' offense wake up tomorrow?" Before the ninth inning, when the San Francisco Giants finally pushed across a run in their 4-1 NLDS Game 3 loss to the Washington Nationals, their offense looked dumbfounded. San Francisco could only muster four hits off starter Doug Fister, all singles. Fister's a tough pitcher who was on a roll Monday, so you can't entirely blame the Giants. But before they scored on Nats closer Drew Storen, the Giants had exactly one run in their previous 17 innings. Doesn't matter how tough the opposing pitching is, that's not how you win postseason games. This, after a Game 2 in which the Giants were one out away from being shutout by Jordan Zimmermann. The Giants won that game, by the force of Brandon Belt's 18th inning homer, but a 2-1 win that took 18 innings is hardly the stamp of an effective offense.
