Serena demolishes Radwanska to reach seventh Australian Open final

World number one Serena Williams remained on course for her seventh Australian Open title after overcoming fourth seed Agnieszka Radwanska in the semifinals on Thursday.

The 21-time American Grand Slam champion claimed a thumping 6-0, 6-4 win over Radwanska in a one-sided contest that lasted just 64 minutes on Rod Laver Arena, Sport24 reported.

With the win, Serena remains only one win away from matching Steffi Graf's Open-era Grand Slam record of 22 titles.

Serena will next face German seventh seed Angelique Kerber, who claimed a 7-5, 6-2 win over Britain's Johanna Konta, in the summit clash.
