The Quarter-Final line-up has been confirmed at the Swiss Indoors in Basel after Day 6 of action.
Stefanos Tsitsipas was one of the big winners on Thursday with victory over Ricardas Berankis who gave him a mightily tough test. This saw him win 6-7, 6-2, 6-4.
Berankis has not made an ATP Tour Quarter-Final since Dubai but he claimed early momentum against Tsitsipas and took the first set.
Despite that though the Greek ace maintained his composure to ease through that early barren spell and claim the next two sets with relative ease.
Wawrinka outlasted Frances Tiafoe in an absolute classic which went the distance and saw the Swiss ace win 6-3, 3-6, 7-5 but despite that an injury means he will not take part in a potential thriller with felllow Swiss legend, Roger Federer who receives a walk over.
Roberto Bautista Agut kept alive his Race to London hopes with victory over Richard Gasquet; there was a defeat though for David Goffin with Riley Opelka doing for him in a close tussle on the indoor courts.
