Andy Murray claimed his 20th win in a row by beating Marin Cilic in straight sets at the ATP World Tour Finals in London on Monday night.
The new world No 1 broke Cilic twice in each set on the way to a 6-3 6-2 victory in front of a packed O2 Arena crowd.
Both players struggled for rhythm in a disjointed opening set and the 6-3 scoreline flattered Murray slightly, but the Scot improved dramatically in the second and was a convincing winner.
Murray started to find his range in the second set and sent this peach of a winner past Cilic in the third game.
Murray made a hesitant start and had to save two break points before finally holding serve in the opening game.
He seemed to have settled when he broke the world No 7 in the second, but Murray struggled on serve once again in the third game and was immediately broken back.
However, Cilic was even more out of sorts and a second break for Murray, in the fourth game, proved enough to take the first set.
Murray then began to relax in the second set and his recent form swiftly came back to him. The first four games were shared, but he then broke twice more to go 3-2 and 5-2 ahead as Cilic’s error-strewn game unravelled.
Murray will now face Kei Nishikori, who beat Stan Wawrinka earlier on Monday, in his second round-robin match, on Wednesday.
