Serena Williams started the defense of her Australian Open title with a dominating 6-2, 6-1 win today against Polish teenager Urszula Radwanska.
Williams also only lost three games in her previous match at Melbourne Park: a 6-0, 6-3 win against now No. 2-ranked Dinara Safina in last year's final.
Despite having her right thigh heavily wrapped with a white bandage, Williams didn't show any signs of restricted movement.
The 28-year-old American hurt her left knee at the Sydney International last Friday and later said she has been bothered by a foot problem.
Williams broke Radwanska in the opening game to set the tone. She broke Radwanska's serve a second time with consecutive backhand winners for a 4-1 lead, then saved break point in the sixth game - the only one she faced during the entire match - in a no-nonsense approach to the match.
Even serving for the set at 5-1 and 40-0, she huffed when her forehand landed too long. On the next point, she clinched the set with an ace.
Radwanska, an 18-year-old who was making her debut in the main draw of the season's first major, saved three match points before dumping a backhand into the net.
Meanwhile, Ana Ivanovic opened with a 6-2, 6-3 win against American Shenay Perry.
Justine Henin advanced with a 6-4, 6-3 win against fellow Belgian Kirsten Flipkens.
On the men's side, sixth-seeded Nikolay Davydenko had a 6-1, 6-0, 6-3 win against Dieter Kindlmann of Germany
No. 21 Tomas Berdych advanced 6-0, 6-3, 6-3 against Robin Haase of the Netherlands.
Fabrice Santoro extended his Grand Slam career into a fourth decade, but he lasted only one match - a 7-5, 7-5, 6-3 loss to 14th-seeded Marin Cilic of Croatia.
