After struggling in tight first sets in her opening two matches, the defending champion moved quickly to defeat Spanish qualifier Maria Jose Martinez Sanchez 6-1, 7-5 Saturday and advance to the fourth round at Wimbledon.
Williams served out the match at love, finishing with a 127-mph delivery — the fastest recorded by a woman at Wimbledon — for her 11th ace.
“Yeah, 127 is a good way to end it,” said Williams, who holds the WTA Tour record at 129 mph.
The four-time champion was barely tested in the first set by the 101st-ranked player. But Williams was pushed to the limit in the second when Martinez Sanchez switched to an effective serve-and-volley game.
“I was very pleased with the performance,” the seventh-seeded Williams said. “Things got close in the second set. She was really playing well, and I had to come up with something more than she was giving.”
Also advancing to the round of 16 was No. 2-seeded Jelena Jankovic, who rallied after dropping the first set and overcame a knee injury to down 17-year-old Danish player Caroline Wozniacki 2-6, 6-4, 6-2 on Centre Court.
Jankovic appeared to hyperextend her left knee while lunging for a shot in the first set and later took an injury timeout to get her knee heavily wrapped. Jankovic plans to have an MRI before facing Tamarine Tanasugarn in the fourth round on Monday.
“It’s very sore now,” she said. “I hope for the best so that I will be able to play my next match.”
The 25-year-old Martinez Sanchez had never won a Grand Slam singles match until this tournament and looked out of her depth in the first set against the six-time major winner. But the left-hander scored repeatedly with serve-and-volley winners and angled drop shots and drop volleys in the second set.
“It was a great strategy,” Williams said. “In the first set it wasn’t working for her from the baseline. I was impressed with the way she changed strategy and made it really competitive in the second.”
The Spaniard rallied from 3-1 down to go ahead 5-4 on serve. But she double-faulted on break point to give Williams a 6-5 lead. Williams finished with 33 winners, as well as 10 unforced errors and six double-faults.
