MELBOURNE, Australia — Caroline Wozniacki advanced to the third round of the Australian Open with an emphatic 6-1, 6-0 win over Vania King today as her first major atop the rankings continued to gather momentum.
The 20-year-old Danish player was never troubled in the 58-minute match, reaching the third round for a 13th consecutive Grand Slam tournament. She has yet to win a major but has held the No. 1 ranking since October and can retain it by reaching the semifinals.
To get to the semis, she might have to beat seven-time Grand Slam winner Justine Henin, who earned a 6-1, 6-3 win over Elena Baltacha.
The two could meet in the quarterfinals.
Three women could finish the tournament at No. 1. Kim Clijsters and Vera Zvonareva are the others, and they opened with straight-sets first-round wins Tuesday.
Clijsters had no charity for former No. 1-ranked Dinara Safina in a 6-0, 6-0 victory.
"I expect my opponent to come out and play their best tennis. She obviously didn't do that," Clijsters said. "But my attitude still was there to try to finish it off and not let her get back in the match."
Wimbledon finalist Tomas Berdych needed four match points to beat Philipp Kohlschreiber 4-6, 6-2, 6-3, 6-4.
No. 8 Andy Roddick had no such trouble, firing his 17th ace to finish off a 7-6 (9-7), 6-2, 6-3 second-round win over Igor Kunitsyn.
The former No. 1-ranked Roddick is into the third round at Melbourne Park for the ninth straight time.
Roddick's friend and U.S. Davis Cup teammate Mardy Fish, a Tampa resident, made a second-round exit, the No. 16 seed losing 1-6, 6-3, 6-3, 6-3 to Tommy Robredo.
