The Serena Williams traveling tennis clinic rolled into Tokyo on Wednesday and, in this land of sushi, it was doughnuts that Williams had on her mind.

"Up 3-0, I thought maybe I could go for 6-0, 6-0," said Williams, the reigning French Open, Wimbledon and U.S. Open champion. "I've never had one in my career . . . it's eluded me so far."

Well, not really. Back in 1998 Williams pitched a shutout against Larisa Neiland.
