Federer beats Karlovic in Miami opener
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.
Federer missed the tournament a year ago as he rested with back pain but has turned his 2014 season around after a low-key 2013.
Last weekend`s finalist at Indian Wells withstood 13 aces from the big-hitting Croatian in the 74-minute win.
Spanish fourth seed David Ferrer made a winning comeback after missing Indian Wells with injury, defeating Teimuraz Gabashvili 6-4, 6-0
French ninth seed Richard Gasquet reached the third round over Alejandro Gonzalez of Colombia 7-6 (9/7), 6-4.
China`s Li Na reached the third round on the women`s side as intended opponent Alisa Kleybanova withdrew with viral illness before their match.
The result sends the second seed into a contest against the winner from Daniele Hantuchova and American Madison Keys.
Two seeds lost in upsets as American Varvara Lepchenko put out seventh seeded Jelena Jankovic 6-3, 2-6, 7-6 (7/2).
Czech Barbora Zahlavova Strycova beat number 13 Italian Roberta Vinci Italy, 6-4, 2-6, 7-5 while Australian open finalist and 10th seed Dominika Cibulkova defeated Yvonne Meusburger 6-1, 6-2.
