Washington: Defending champion Alexander Zverev outlasted Japan’s Kei Nishikori 3-6 6-1 6-4 to reach the ATP Washington Open semifinals while three-time Grand Slam champion Andy Murray withdrew citing fatigue.
Germany’s third-ranked Zverev, seeking his fifth final of the season and third title of the year after Munich and Madrid, on Friday dispatched seventh-seed Nishikori, the 2015 champion, as he did in last year’s Washington semi-finals.
Zverev booked a semi-final against 10th-seeded Greek 19-year-old Stefanos Tsitsipas, who eliminated Belgian third seed David Goffin 6-3 6-4 in just 74 minutes. Australian Alex De Minaur, another 19-year-old, reached the semi-finals by walkover when Murray withdrew, citing the fatigue of three grueling three-set wins that kept him on the court more than eight hours in total.
Murray, who also withdrew from next week’s Toronto Masters event, was in only his third event back and first hardcourt event since March 2017 at Indian Wells after an 11-month layoff.
