Stan Wawrinka reached the quarter-finals of the Rotterdam Open by gaining revenge over Milos Raonic, but Stefanos Tsitsipas surprisingly bowed out in the first round.
Having suffered a third consecutive defeat to Raonic at the Australian Open last month, Wawrinka beat the big-serving Canadian 6-4 7-6 (7-4) on Thursday morning.
The three-time grand slam champion's previous win over Raonic came en route to winning this tournament four years ago and he claimed the only break of the match in the first set before edging a second-set tie-break.

Australian Open semi-finalist Tsitsipas fell at the first hurdle, Damir Dzumhur defeating the third seed 6-4 1-6 7-5.
Gael Monfils reached the quarter-finals by rallying to beat Andreas Seppi 4-6 6-1 6-3, while Daniil Medvedev, Jo-Wilfried Tsonga and Marton Fucsovics all made it through to round two.
