It was not the moment for posterity that KNBR had in mind, but it was unforgettable nonetheless.
KNBR broadcaster Dave Flemming was making the call on Barry Bonds' historic 715th home run Sunday when his microphone went dead, leaving the radio audience with crowd noise for more than 10 seconds until fellow broadcaster Greg Papa rushed on the air to pick up the proceedings and describe the achievement.
"If you'd only heard the rest of it, it was an unbelievable call,'' said Flemming, who was initially unaware that he wasn't being heard over the air. "It's too bad we don't have proof. I have to joke about it because it's too painful to think about."
