Remember way back when the A's scored 14 runs against thedivision rival Los Angeles Angels ? OK, so that blowout victory happened just five days ago. It sure seems like ancient history. The A's are generating the wrong kind of momentum right now.They made hardly a whimper Saturday in a 3-0 loss to the Giantsbefore a sold-out crowd at AT&T Park. Granted, two-time Cy Young Award winner Tim Lincecum can createheadaches for any lineup. He limited the A's to three hits intossing his eighth career complete game and third againstOakland.
