Andy Murray eased into the second round at the Rotterdam World Tennis tournament with a 6-3 6-3 success over Frenchman Edouard Roger-Vasselin.
Murray wasted little time stamping his authority on the contest, taking the first set after securing two breaks of the Roger-Vasselin serve.
The No 2 seed hit nine more winners in the first set than his opponent and two fewer unforced errors, converting two break points from nine chances while Roger-Vasselin had none.
Murray showed his battling qualities in the fifth game of the second set, saving two break points from 15-40 down before moving into a 4-1 lead.
Murray went on to serve out victory at the first attempt and will next play Austrian qualifier Dominic Thiem, who got the better of Finn Jarkko Nieminen 6-4 4-6 6-4.
"I served really well for a set and a half, at the end it's natural that you get a bit nervous, I moved well and made him play the extra ball," said Murray.
"It got tough at the end and I'm glad I pulled this one off in two sets. I hope to have another good run here this week."
The winner between Murray and Thiem will play Marin Cilic in the quarter-finals after the Croat upset No 5 seed Jo-Wilfried Tsonga 6-4 6-4 in the evening match.
Also on Wednesday, top seed Juan Martin Del Potro saw off Frenchman Gael Monfils 7-6 (8/6) 6-3.
Richard Gasquet needed three sets to overcome Dutchman Thiemo de Bakker. The Frenchman lost the opening set in a tie-break, but fought back to triumph 6-7 (7/5) 7-6 (7/2) 6-3.
German No 6 seed Tommy Haas eventually triumphed 6-7 (7/4) 7-6 (7/1) 7-5 over Fernando Verdasco, while Nicolas Mahut beat Daniel Brands 7-5 6-3.
