Wawrinka outlasts Lopez to reach Antwerp quarter-finals
Stan Wawrinka has reached the quarter-finals of the European Open in Antwerp as the Swiss veteran outlasted Feliciano Lopez 6-7(4) 6-4 7-6(4).
The 34-year-old Wawrinka, seeking his first ATP trophy since he lifted the title in Geneva two years ago, served 17 aces -- one less than Lopez -- and converted one out of four break-point opportunities to edge the tight match.
Wawrinka has beaten Simon four times in seven meetings but the Frenchman prevailed in straight sets the last time they played each other on the hardcourts of Shanghai in 2016.
Argentina's Guido Pella joined the duo in the last eight after beating South Korea's Kwon Soon-woo 7-5 7-5 to set up a clash with Ugo Humbert or second seed David Goffin.
In first-round action, Pablo Cuevas beat Hugo Dellien 6-4 6-3 and will take on Briton Andy Murray next. American Frances Tiafoe overcame Germany's Yannick Maden 7-6(7) 6-3.
