Tennis: Federer bites the dust in Miami

ROGER FEDERER crashed out at the fourth round of the Sony Ericsson Open in Miami as Tomas Berdych triumphed 6-4, 6-7(3/7), 7-6(8/6) in a gruelling battle.

The world No.1 committed 62 unforced errors and was broken three times as Berdych of the Czech Republic fought through in just under three hours, ending an eight-match losing streak against the Swiss star.

The 16th seed saved eight of ten break points – with seven of those coming in a tense second set – on his way to the quarter-finals and a clash with Fernando Verdasco.

Rafael Nadal was made to suffer before triumphing 7-6(7/5), 6-4 over compatriot David Ferrer in a gritty affair full of unforced errors.

The Spaniard will face eighth seed Jo-Wilfried Tsonga after he dismantled former world No.1 Juan Carlos Ferrero 6-2, 6-2.

Andy Roddick will face Spain's Nicolas Almagro in the last eight after recovering from an awful start to beat Germany's Benjamin Becker.
