Big-serving Czech Tomas Berdych caused the first major upset of the Rome Masters yesterday when he ousted World No 1 and top seed Novak Djokovic of Serbia.

Berdych, who had beaten Djokovic only once in their last 14 meetings, prevailed 6-2, 7-5, 6-4 to book himself an unlikely place in the semi-finals and boost his chances ahead of the French Open.
