New York - British third seed Andy Murray advanced to the quarter-finals of the US Open on Monday by defeating Canadian 15th seed Milos Raonic 6-4, 6-4, 6-2.
Olympic champion Murray, seeking his first Grand Slam title, will play for a berth in the semi-finals against Croatian 12th seed Marin Cilic.
The 25-year-old Scotsman reached his eighth Grand Slam quarter-final in a row.
Murray broke Raonic with a drop volley winner for a 5-4 lead and held to take the first set after 36 minutes. In the second set, Murray broke for a 3-2 edge when Raonic netted a forehand and held serve from there to seize command.
Raonic, trying to become the first Canadian man in a Grand Slam last eight in the Open era, surrendered breaks in the third and fifth games of the final set and Murray, who never faced a break point, held serve to end matters after two hours with a service winner.
