Milos Raonic advanced to the last eight of the Japan Open in a matter of moments Thursday after Serbian opponent Viktor Troicki retired from their match with an injury in the first set to hand the Canadian a 3-0 win.
Raonic moved into the quarter-finals of the ATP 500 event after losing in the second round in his first two appearances in 2010 and 2011 — both to Rafael Nadal.
The hard-serving 21-year-old from Thornhill, Ont., will face Janko Tipsarevic of Serbia in the next round after the third seed defeated Swiss qualifier Marco Chiudinelli 6-4, 6-2.
