World number one Roger Federer stepped up his bid for a sixth Indian Wells Masters title with a 6-2, 6-1 demolition of Filip Krajinovic on Monday. The 36-year-old marvel continues to defy the ageing process as he needed just 58 minutes to overpower the Serb with a brilliant display of Swiss timing. "I was feeling like he was not loving my slice and I was also mixing in dropshots," said Federer who extended his perfect record this season to 14-0. "I really I was able to mix up my game nicely, make it difficult for him. "At the same time, have fun with my game, play a variation, but for the most part try to stay on the offensive."
