Zverev in first GS last 8

Paris (AFP): German second seed Alexander Zverev claimed his third successive comeback win at the French Open to reach his first Grand Slam (GS) quarter-final on Sunday, edging Russian Karen Khachanov in five sets. 

The 21-year-old played some stunning tennis in the closing stages of a dramatic 4-6, 7-6 (7/4), 2-6, 6-3, 6-3 fourth-round victory and will next face Dominic Thiem who reached a third successive quarter-final in Paris by seeing off Japan's Kei Nishikori 6-2, 6-0, 5-7, 6-4. 

American tennis player Madison Keys defeated 31st-seed Mihaela Buzarnescu of Romania 6-1, 6-4 to advance into the quarterfinals for the first time in her career. 

The 2017 US Open finalist earned her victory in 65 minutes and has not lost a single set in this year's French Open, reports Efe. 

Keys, 23, gave a dominant performance throughout the match, while Buzarnescu did herself no favors with 11 unforced errors in the first set and 16 in the second.
