Sharapova into Miami semi-finals

Mario Sharapova came from a set down to beat her fellow former world number one Caroline Wozniacki and book her place in the final of the Sony Ericsson Open in Miami this morning.

The second-seeded Russian claimed a 4-6 6-2 6-4 victory in just more than two and a half hours in a match which featured 10 breaks of serve.

Fourth-seed Wozniacki started the stronger, punishing her opponent's second serve as she broke three times to take the first set.

However, the Dane barely got a look in in the second as Sharapova raised her game, making 92% of first serves as two breaks handed her the set in convincing fashion.

The former Wimbledon champion broke twice more in the decider to take victory.

In the quarter-finals of the men's draw, Argentina's Juan Monaco made short work of home favourite Mardy Fish with a 6-1 6-3 win.

The 21st seed upset his eighth-seeded opponent, breaking five times as he claimed victory in one hour 22 minutes.
