Script:

Maria Sharapova booked her place in the last four of the Madrid Open after edging a tight quarter-final against second seed Li Na.

The Russian eighth seed looked to be heading out as she blasted this wild backhand wide to hand Li Na the first set.

However, Sharapova didn't make the same mistake twice. She broke back immediately with a backhand winner and eventually won the tie break to level the match.

Sharapova prevailed in the deciding set to win 2-6, 7-6, 6-3 at Caja Mágica, which means The Magic Box in English. The 27-year-old will be hoping for a spell-binding performance against Poland's Agnieszka Radwanska in Saturday's semi-final.
