Federer into last eight of Swiss tournament

Roger Federer rolled into the quarter-finals of the 1.2 million Swiss Indoors tournament Thursday with a 6-1 6-4 victory over unseeded Argentinian Juan Martin Del Potro.

Switzerland’s world number one has 12 grand slam championships and 51 singles titles, but it wasn’t until 2006 that he finally broke through here in his home country.
