(Reuters) - Roger Federer began his pursuit for a sixth Swiss Indoors Basel title with an explosive 47-minute 6-2 6-1 victory over Gilles Muller on Wednesday after Rafael Nadal reached the quarter-final with a 6-1 6-1 win against Pierre-Hugues Herbert.
Top seed Federer hit 12 winners in a 24-minute first set and the Swiss 17-time grand slam champion continued his domination in the second set without losing a single point on his serve.
