You'd have thought they won the whole damn thing. That rarest ofsights - a clutch line drive - had fallen safely into right-centerfield for a game-winning single, and the Giants sprinted out of the dugoutlike wild men, jumping all over Jeff Keppinger and forming a pileof humanity on the edge of the infield. It was a 2-1, 10-inning victory over the horrible Houston Astroson Saturday night, and seldom has an evening of futility ended sowell. This had been yet another procession of unwatchable at-batsby the Giants' weakest-hitting team sincethey moved to San Francisco, without the slightest hint that PabloSandoval could hit right-handed or that a couple of much-neededmainstays, Aubrey Huff and Cody Ross, had found the magic.
