Serena Williams does not enjoy viewing videos of her losses. Not one bit.

She used to engage in that sort of film work, Williams said, but "it was so painful; it was like stabbing myself.''

So even though Williams knew her third-round opponent at the U.S. Open would be the same woman she lost to at the Australian Open, preparing by studying a replay of that January defeat simply was out of the question.

Did not seem to matter at all.

After splitting Saturday's first eight games against 42nd-ranked Ekaterina Makarova of Russia, the fourth-seeded Williams got into high gear and breezed to a 6-4, 6-0 victory, reeling off the last eight games in a row.

"Definitely was motivated. Knowing that I lost; could definitely happen again. Did not want that to happen,'' said Williams, who hit 13 aces to raise her tour-leading total this season to 408.

"I really hate watching matches that I lose, unless I'm punishing myself,'' added the 14-time Grand Slam champion. "I didn't punish myself.''

She hasn't been losing much lately.

Since the only first-round Grand Slam exit of her career, against 111th-ranked Virginie Razzano at the French Open on May 29, Williams is 22-1 in singles, including the title at Wimbledon and gold medal at the London Olympics.

That sort of excellence sure saves money for clothes: Williams said she threw out all of the dresses she brought to Paris to wear during matches there.

No such problems so far in New York, where Williams has dropped only 12 games entering her fourth-round match against 82nd-round Andrea Hlavackova of Czech Republic.
