Raonic books spot in knockout stages

Milos Raonic has joined Novak Djokovic in booking a place in the knock-out stages of the ATP World Tour Finals, in London.

A 7-6, 6-3 straight sets victory over Dominic Thiem saw fourth seed Raonic progress into the semi-finals of the competition, where he will meet the top qualifier in the group containing Andy Murray, Stan Wawrinka and Kei Nishikori.

Raonic began the encounter in imperious fashion with 10 winners in his first three service games, but Thiem stood firm and took the set to a tie-break.

At 4-2 up, Thiem looked favourite to edge in front, but Raonic recovered, with his exemplary serving seeing him take the tie-break 7-5.

Thiem slipped further behind when he dropped his serve in the opening game of the second set and he was never able to recover.

Raonic broke again to seal the match when leading 5-3 after Thiem sent a backhand into the net.
