MIAMI (Reuters) – World number one Roger Federer became the latest upset victim at the Sony Ericsson Open after going down 6-4 6-7 7-6 to sixteenth seeded Czech Tomas Berdych in the fourth round on Tuesday.

The 16-times grand slam champion had beaten Berdych in eight of their previous nine encounters but paid the penalty for an error-strewn display in which the Swiss top seed could only convert two of 12 break point opportunities.

Federer's defeat means the top three men's seeds have all been knocked out after Serbia's Novak Djokovic and Britain's Andy Murray both suffered shock defeats earlier in the tournament.

Earlier, world number eight Andy Roddick needed to overcome a sluggish start to book his ticket to the quarter-finals while Rafa Nadal also advanced after being tested early in his match.

Roddick, fresh from finishing runner-up at Indian Wells, beat Germany's Benjamin Becker 7-6 6-3 while Nadal brushed past Spanish compatriot and Davis Cup team mate David Ferrer 7-6 6-4.

The big-serving American fell behind 4-1, 0-40 in the first set but rallied back against Becker. After breaking to get to 4-3, Roddick served a 134 mph (214kph) ace as he tied it 5-5.

It was downhill from there for the unseeded Becker as Roddick won the tiebreaker 7-4 before easing through the second set.
