Australian Open 2018: Angelique Kerber thrashes Madison Keys to reach semi-finals

Two-time Grand Slam champion Angelique Kerber thrashed Madison Keys in just 51 minutes to reach the Australian Open semi-finals.

The 30-year-old German was in brilliant form as she beat American Keys 6-1 6-2 on Rod Laver



Arena.

Keys, a 2017 US Open finalist, struggled badly throughout, winning only 18 of 46 points on her own serve.

Kerber, the 2016 champion in Melbourne, will play world number one Simona Halep or Karolina Pliskova in the last four.
