MELBOURNE — Four-time champion Roger Federer continued to roll back the years as he took apart Mischa Zverev, 6-1 7-5 6-2, with a clinical display of all-court tennis to reach his 13th Australian Open semifinal in 92 minutes on Tuesday.
Chasing an 18th grand slam title, and first since 2012, the 35-year-old Federer neutered his left-handed German opponent’s serve-volley game to set up a last-four meeting with fellow Swiss Stan Wawrinka.
