Third-seed Andy Murray opened his title defence in the Aegon Championships with a straight set win, while top seed Stanislas Wawrinka also moved into the next round at The Queen's Club on Wednesday.
Murray, who was playing his first match under newly-appointed coach Amelie Mauresmo, overpowered Paul-Henri Mathieu 6-4, 6-4 in just 84 minutes. The Scot converted two break points and won 75 percent points on his first serve.
Murray displayed his trademark backhand winners towards the end of the match and played with his usual style. The two-time Grand Slam champion said he received few inputs from his new coach Mauresmo, but he is not going to make any major changes in his playing style before Wimbledon.
"We spoke a bit about the match and the tactics and then chatted a little bit afterwards," Murray said. "But this week there's not going to be any big changes in my game. I also wouldn't expect any before Wimbledon.
"We'll definitely work on some things after the tournament is finished here. We will chat about the stuff that I will be working on over the next few days, and then when I get the chance to after the tournament is finished here, I'll get four or five days of practice where I can work on some things."
In the third round, world number five Murray will face No. 15 seed Radek Stepanek, who defeated Australian Bernard Tomic 7-6 (7-4), 7-6 (7-5) in a closely-contested match.
Meanwhile, Marcus Baghdatis of Cyprus was forced to retire with a shoulder injury, which allowed Australian Open champion Wawrinka to reach the third round in just 16 minutes. Wawrinka was leading the match 3-2 when Baghdatis pulled out of the contest.
The Cypriot, who was handed a wildcard for Wimbledon, is confident of recovering before the Grand Slam.
"Hopefully it will be three or four days, but I should be fine for Wimbledon," Baghdatis said. "There shouldn't be any problems with that. It's disappointing to miss out but you can't do anything about injuries, all I have to do now is work hard to get ready for Wimbledon."
In another second round encounter, Feliciano Lopez stunned former champion Lleyton Hewitt of Australia 6-3, 6-4. The 10th seeded Lopez will now face Kenny De Schepper, who defeated Ernests Gulbis, in the next round.
"It was just frustrating," said Hewitt. "I played a bit of a loose game the second game of the match. Then he served really well the whole match.
"He had a lot better rhythm today [Wednesday] than he did yesterday in his first round match. I just couldn't quite get enough pressure on his service games and he hit his spots really well."
