MIAMI: American Lindsay Davenport rolled back the years by crushing world number two Ana Ivanovic 6-4 6-2 in the Sony Ericsson Open third round.

Top seed Justine Henin, Svetlana Kuznetsova and the Williams sisters all advanced safely to the fourth round but the experienced Davenport took centre stage with her victory over in-form Ivanovic.

The Serb, who arrived in Miami after winning the Pacific Life Open title, had no answers to the aggressive game brought to the court by world number 33 Davenport.

 "My intensity wasn't up there today," Ivanovic said. "When you play against such a champion, you need to be on the ball for each point."

Ivanovic is the second top-10 player Davenport has beaten since returning to the tour last September after giving birth to her first child.

Davenport won 13 of 14 points at the net and cancelled out her 20 unforced errors with 20 winners.

The former world number one led 6-4 3-0 when it appeared Ivanovic might fight back when she broke serve in the fourth game, but Davenport recovered the break immediately.

Davenport, who skipped the Sony Ericsson Open for many years because she thought playing both the Pacific Life Open and Miami was too difficult, was not surprised that Ivanovic struggled.

"Sometimes you never know what to do expect when you go out for a certain match on a certain day," Davenport said. "Obviously, she's had a great year so far. But it's very tough to play Indian Wells and Miami back-to-back, doing well in Indian Wells."

Meanwhile in the other matches, Russian third seed Kuznetsova, the 2006 champion, saved a match point before beating world number 27 Victoria Azarenka of Belarus 1-6 7-5 6-0.

Henin dispatched Sara Errani of Italy 6-2 6-1 in just 64 minutes, breaking the world number 72 five times.

However, Serena Williams had to overcome 60 unforced errors to beat Flavia Penetta 6-7 6-3 6-2 after trailing the Italian 3-0 in the second set.

But her sister sixth seed Venus Williams had no such worries as she spent only 67 minutes on court, taking care of wildcard Marina Erakovic of New Zealand 6-2 6-1.
