Angelique Kerber beats Serena Williams to win Australian Open

Kerber had won just one of her previous six matches against Williams

Germany's Angelique Kerber stunned world number one Serena Williams in three sets to win her first Grand Slam title at the Australian Open.

Kerber, seeded seventh, won a thrilling final 6-4 3-6 6-4.

The 28-year-old is the first German to win a major singles title since Steffi Graf at the 1999 French Open.

Williams, 34, was beaten for just the fifth time in 26 Grand Slam finals, and missed out on the chance to tie Graf's open-era record of 22 titles.
