MELBOURNE (Reuters) - German seventh seed Alexander Zverev recovered from a slow start to beat former champion Stan Wawrinka 1-6 6-3 6-4 6-2 in the Australian Open on Wednesday to reach his first career Grand Slam semi-final.

Zverev was once considered one of the leading 'Next Gen' contenders to break the Grand Slam hegemony of Novak Djokovic, Rafa Nadal and Roger Federer who have shared the last 12 majors between them.
