He was out of sorts on all manner of shots, accumulating 30 unforced errors and only 12 winners through the first two sets.advertisementHe managed to lead 3-0 and 4-1 in the second set, but that was just about all he had in him.When that set ended, Djokovic had a trainer on for a massage, but soon thereafter, his title defense was over.Djokovic entered the night with a 19-5 head-to-head edge against Wawrinka across their careers. This, though, was their first meeting since the 2016 U.S. Open final, won by Wawrinka.This scuttles the possibility of a semifinal between Djokovic and 20-time major champion Roger Federer, which would have been a rematch of their historic Wimbledon final in July. Djokovic won that one in an unprecedented fifth-set tiebreaker after nearly five hours.Also Read | US Open: Daniil Medvedev urges fans to keep on booing after reaching quarter-finalsAlso Read | Roger Federer trounces David Goffin to make US Open Quarter-finalsAlso See:For sports news, updates, live scores and cricket fixtures, log on to indiatoday.in/sports.
