Roger Federer happy with Australian Open performances

Former world number one Roger Federer has revealed that he has been pleased with his performances at the Australian Open so far.

The Swiss player booked his place in the fourth round of the Grand Slam in Melbourne earlier today courtesy of a 6-2 6-2 6-3 victory over Teymuraz Gabashvili, meaning that he is yet to drop a set.

Speaking after that match, Federer said: "I'm happy that from my side I'm winning my matches in straight sets. It's been different conditions every match. The heat first and the indoor match and now normal conditions today with a bit of wind.

"So it's just good to get through and get a good feel out there and make sure if you've got a chance to win your matches easier to do so. That's what I was able to do today, so I'm pleased."

Federer will now take on Jo-Wilfried Tsonga for a place in round five.
