Agnieszka Radwanska and Angelique Kerber were both easy second-round winners Wednesday at the Australian Open.

The fourth-seeded Radwanska of Poland converted on 6-of-12 break chances and capitalized on 38 unforced errors by Romania's Irina-Camelia Begu during a 6-3, 6-3 victory at Rod Laver Arena.

Radwanska, who has now won 11 straight matches and 22 consecutive sets, is seeking her third title in as many events this season.

Germany's Kerber, the tournament's fifth seed, overcame three double faults by holding Lucie Hradecka of the Czech Republic to just 2-for-7 on break opportunities en route to a 6-3, 6-1 win in a little over an hour.

Hradecka also recorded three double faults and made 39 unforced errors while failing to advance past the second round at this event for the second straight year.

The lone seeded player to fall so far in the second round is 23rd-seeded Czech Klara Zakopalova, who dropped a 6-1, 6-0 decision to Belgium's Kirsten Flipkens.

Flipkens converted on 6-of-12 break opportunities and took advantage of a pair of double faults by Zakopalova to advance past the second round of the Aussie Open for the first time in five appearances.
