Preview: The Sony Ericsson Open 2012 has reached the crunch stage of the tournament with the women's semi-finals taking place on Thursday.

First up is another battle of former-world No. 1s as Caroline Wozniacki takes on Maria Sharapova. Wozniacki produced her best win in some time in defeating Serena Williams in the quarter-finals and will look to take the momentum from that win into today's matchup.

Having faced all manner of criticism during her time at the top of the rankings for not winning a major, the Dane has now dropped to No. 6 and it may be that the pressure on her no longer being so intense will aid her game.

Sharapova, meanwhile, will be desperate to take advantage of the fact that her recent adversary Victoria Azarenka has been taken out. Azarenka crushed the Russian in the finals of both the Auatralian Open and indian Wells and Sharapova will be looking to claim her first title of the season in the new world No. 1's absence.

The other WTA semi-final sees Azarenka's conqueror, Marion Bartoli, take on the player who has been tormented more than any other by the Belarusian's unbeaten start to the season, Agnieszka Radwanska. The Polish No. 5 seed has tasted defeat to Azarenka four times this season, representing her only losses in 2012.

Radwanska continued her good start to the year by claiming the scalp of Venus Williams in the quarter-finals and must surely be relieved to have discovered that it would be Bartoli and not Azarenka who stood between her and the place in the Miami final.

But it would be wrong to take Bartoli lightly. The French No. 7 seed played superbly to end Azarenka's streak yesterday and must surely take a massive amount of confidence from the win.

History does not bode well for Bartoli, however. Radwanska has won six out of six of the pair's meetings, with all but the first victory coming in straight sets.

Sandwiched between the women's semi-finals on Thursday will be the last of the two men's quarter-finals. Not before 3 p.m. ET, Mardy Fish takes to the court to take on Argentinian Juan Moncao.

Following a break-out year in 2011, Fish has had a massively disappointing start to this season. Indeed, before Miami, the American had not won more than a single match at any of the four tournaments in which he competed.

And the 30-year-old will be looking to take advantage of a relatively kind draw to reach the semi-finals in Miami for the second-straight year.

Following that the world No. 1, Novak Djokovic, will be in action against tough Spaniard David Ferrer. Although Ferrer went down in straight sets at the Australian Open back in January, the No. 5 seed has given the Serbian problems in the past and got the win over an admittedly jaded Djokovic in the Barclays ATP World Tour Finals at the end of last year.

If Djokovic is not at his best then Ferrer is the ideal player to capitalize.
