Jonathan Sanchez routinely flirts with disaster but just asroutinely finds a way to worm his way out of it. But Sanchez got knocked off his tightrope Saturday night. He notonly had his shortest outing of the year but also absorbed adecisive knockout -- a four-run A's fifth -- as the Giants dropped their second straightat O.co Coliseum, 4-2. To make matters worse, San Francisco's offense was a no-showonce again. The Giants left 10 runners on baseagainst six Oakland pitchers and blew several prime opportunitiesto score. Once they finally did scratch out two runs, Sanchez gaveit right back and then some.
