ROGER Federer has worked hard to make Swiss efficiency his trademark.

In the early stages of Grand Slams he conserves his energies by practising that old mantra of minimum effort for maximum reward.

And nowhere was that more evident than in his 6-2 6-2 6-4 second round win over Guillermo Garcia-Lopez.

The second seed and fivetime champion was on and off court in just one hour and 29 minutes and barely broke sweat in the process.

If Andy Murray was watching – which he would have been – this display should have sent him scurrying to the nearest practice court.

Garcia-Lopez – a clay court loving Spaniard from the “grass is for cows” school of tennis – never really stood a chance and could only shrug as a succession of unstoppable winners sailed past.

And when Federer is winning a near flawless 94 per cent of his first serves, he simply doesn’t lose.

“I was quite surprised I won so easily,” admitted Federer.

“I expected a hard match because he’d been playing well but it felt really good.

“I definitely didn’t have to play my very best but it was solid and that’s exactly what I needed.

“There are many rounds to go for guys to have a crack at me, with nothing to lose, but if I can keep up my level I’ll get through.

“I’m feeling confident and I hope it’s going to last for a while now.”

Fourth seed Novak Djokovic also progressed in straight sets, 7-5, 6-1, 6-4, against Germany’s Simon Greul.

But perhaps he’d caught a glimpse of Federer’s performance, his downbeat postmatch analysis was the opposite of fighting talk.

“I have no expectations for Wimbledon – I don’t need to create any additional pressure on myself because it is hard to deal with,” said Djokovic, right.

“I’m aware of my qualities but I’m happy that people are not talking about me at the moment.

“Grass courts are not as suitable for my tennis as hard or clay courts but I still think I have an allaround game that can be competitive on any surface.”

Meanwhile, Alex Bogdanovic has hinted he might focus his attention on doubles tennis – the day after recording yet another Wimbledon defeat.

The British number three lost his eighth consecutive men’s singles match on Tuesday but rebounded to beat David Martin and Jean- Claude Scherrer, along with British teammate James Ward, in the first round of the men’s doubles.

Only Murray and Elena Baltacha have progressed beyond the first round at the All England Club.

And Murray has questioned the lack in depth after nine home players were skittled over in the first two days of the championship.

“I know I’m a talented guy.

I work hard and I put in the hours but I’ve still lost eight times at Wimbledon,” said Bogdanovic.

“Andy is right, there is a gap but we are working hard to close it.

“I’m an easy guy to criticise but it doesn’t bother me. As long as I keep improving and I keep working then I will be back to give it another shot.”

Elsewhere, British pair Jamie Delgado and Jonny Marray advanced after their opponents retired but there was disappointment for British doubles number one Ross Hutchins, who suffered a surprise defeat.

Hutchins and Australian Stephen Huss, seeded 16, were beaten in five sets by qualifiers Prakash Amritraj and Aisam Ul Haq Qureshi, going down 6-4, 6-7, 6-4, 3-6, 6-3.
