Sharapova moves into semis

Maria Sharapova moved a step closer to a fourth consecutive final appearance at the Sony Open as she overcame Petra Kvitova in straight sets.

The Russian has never won at Crandon Park in Miami, but has made the final five times, including the last three years.

She is now just one match away from another final after advancing to the semis with a 7-5 6-1 win over her fellow former Wimbledon champion.

Sharapova broke her Czech opponent four times en route to victory with Kvitova winning just 28 per cent of points on her second serve.

She did not have things all her own way in the first set but, having got her nose in front, the Russian began to dominate her rival and wrapped up victory in just over an hour and a half.
