Lexus ATP Head2Head: Taylor Fritz caused a major shock at the Australian Open on Sunday, the American beating last year's runner-up Stefanos Tsitsipas 7-6(7-3), 5-7, 6-3, 6-3 to reach the quarterfinals.

The 12th seed produced brilliant tennis throughout as he wrapped up victory in just over three hours to set up a clash with 10-time champion Novak Djokovic in the last eight.

Fritz struck 50 winners and committed just 19 unforced errors, while Tsitsipas held a 41/33 mark.
