( CNN ) -- Andy Murray has spent much of the past few weeks watching the action unfold on the television -- but the World No.2 says his injury-enforced absence has rekindled his passion for tennis . The Briton , who reached the final at Wimbledon last year , returned to Queen 's Club Thursday to finish off his rain delayed game with Nicolas Mahut before sweeping aside Australia 's Marinko Matosevic 6-2 6-2 in 56 minutes . And after shrugging off a recurrence of the back injury which he suffered at the Rome Masters in May , Murray is far more grateful for the time he spends on court after being forced to withdraw from the French Open . `` I think it can be easy to take things for granted sometimes , '' Murray told reporters . `` You know , I played pretty much every Slam for about seven years and I missed it . It was difficult watching and not being there . `` You realize how much you love competing and you love being around the tournaments . `` When everything is good and you 're healthy and you 're playing every week you do n't often think about it that much . `` And when you 're away from it and you miss one of the biggest tournaments , one of the tournaments you prepare extremely hard for and put the hard work in for , then it 's tough . `` I was really looking forward to getting back on the court again and hopefully I can have a good week . '' Murray was beaten by Roger Federer in the final at Wimbledon just over 12 months ago but got revenge on the Swiss by taking Olympic gold in fine fashion . And after coming through the best part of two games in a single day , the 26-year-old is confident he 's well on the way to regaining full fitness . `` I feel good . That was what was most pleasing about the matches , '' Murray said . `` There was a lot of stops and starts on Wednesday , having to warm up and cool down and stuff . `` But everything felt good and I woke up this morning with no real stiffness , which is good . `` I thought I moved pretty well . Normally the first couple of matches here the court is quite slippery , and that 's something I have struggled with the last few years . `` This time I have n't slipped down once . That has been a good sign . '' Murray , who will be back on court Friday to face Germany 's Benjamin Becker in the quarterfinals , added : `` I probably feel a bit more confident coming into this grass court season because of how I played on it last year . `` I think because I managed to win some big matches and play well on the grass last year , I know what I did well and what I need to keep doing . '' Elsewhere , Lleyton Hewitt continued his impressive run of form with a 5-7 6-3 6-4 win over American Sam Querrey . Hewitt , 32 , will face former U.S. Open winner Juan Martin del Potro , who needed less than an hour to see off British wildcard Dan Evans . Second seed Tomas Berdych eased through to the last eight with a 6-3 6-4 win over Slovenia 's Grega Zemlja and will now face defending champion Marin Cilic . Jo-Wilfried Tsonga was forced to play two three set matches in one day to book his place in the quarterfinals and a meeting with America 's Denis Kudla . Tsonga , seeded fourth , defeated fellow Frenchman , Edouard Roger-Vasselin 6-3 6-7 6-3 early Thursday before seeing off Dutchman Igor Sijsling 7-5 5-7 6-3 . Elsewhere , Tommy Haas continued the defense of his title at the Halle Open by reaching the last eight with a straight sets win over Ernests Gulbis . Haas will play Gael Monfils for a place in the last eight . There were also wins for 2011 champion Philipp Kohlschreiber and France 's Richard Gasquet .
