Australian Open: Alexander Zverev reaches semi-final

Alexander Zverev is through to a grand slam semi-final for the first time after defeating Stan Wawrinka in four sets at the Australian open.

The German seventh seed beat the Swiss three-time grand slam champion 1-6 6-3 6-4 6-2, dropping a set for the first time in Melbourne this year.

He lost the first five games in only 16 minutes but bounced back to convert five out of 13 break points.

The 22-year-old will face Rafael Nadal or Dominic Thiem in the last four. Roger Federer will face last year’s Australian open winner Novak Djokovic on Thursday.
