World No 2 Roger Federer and number three Novak Djokovic eased into the third round of the Miami ATP Masters 1000 tournament Friday with victories over qualifiers. Federer, playing just his second tournament since losing to Rafael Nadal in the final of the Australian Open, beat American Kevin Kim 6-3, 6-2.
Federer said it was always tricky taking on an unfamiliar opponent, even one ranked well below him.
The 13-time Grand Slam champion next faces Germany's Nicolas Kiefer, a 5-7, 7-6 (7/5), 6-2 over France's Fabrice Santoro.
Djokovic booked his third-round berth with a 6-3, 6-2 victory over Canadian Frank Dancevic 6-3, 6-2.
