Watch highlights from Day 4 at the Miami Open presented by Itau, as Roger Federer and David Ferrer both produced impressive comebacks from a set down to reach the third round. The Swiss, following his win over Radu Albot, said: "It's always going to feel very different in a massive place like this.
Yeah, it was definitely different, especially very different to Key Biscayne last year. I'm happy I got it out of the way. I'm happy I was able to find a way tonight. It was a good atmosphere at the end. I thought it was quite electric, how it usually is in Miami."
