Miami: Roger Federer began his campaign at the WTA and ATP Miami Masters on Friday with a 6-4, 7-6 (7/4) defeat of Ivo Karlovic. The fifth-seeded Swiss, now 11-1 all-time against the Croatian, was impeccable in the opening set, losing his only point on serve as he stood 5-4, 40-0 moments before serving out the opener.
A winning tie-break in the second finally made the difference for Federer, now 42-12 in Miami with titles in 2005 and 2006. "I made sure I had a lot of first serves in, made sure I stayed aggressive from the baseline," Federer said. "I think it worked really well, hardly any unforced errors.
"I was able to move Ivo around and I was able to maintain that throughout the match, which was key. I could focus a bit on returning while then holding serve, which is important against Ivo."
