( CNN ) -- Russia 's Maria Sharapova has admitted she is desperate to win the Miami Masters , a tournament where she has been beaten in the final on four different occasions . The third seed , who fell at the final hurdle in both 2011 and 2012 , made it through to the semifinals for the third year in a row after beating Sara Errani of Italy 7-5 , 7-5 . Sharapova 's semifinal opponent will be Serbia 's Jelena Jankovic after the former world No . 1 beat Errani 's compatriot Roberta Vinci 6-4 6-7 ( 6-8 ) 6-3 . Sharapova may have won four grand slams but following defeats in 2005 , 2006 , 2011 and 2012 , she would love to add a success in Key Biscayne to those triumphs . Poland 's Radwanska is the defending champion , furthering the Russian 's Miami misery last year to add to previous final failures against Victoria Azarenka ( 2011 ) , Svetlana Kuznetsova ( 2006 ) and Kim Clijsters ( 2005 ) . `` I 've been so close to winning . I would love to win it , '' Sharapova told reporters after seeing off the eighth seed . `` I 've been coming to this tournament since I was a little kid . It would mean a lot to win it . '' The world No . 2 had to work hard for victory against Errani , who she defeated in last year 's French Open to achieve her career grand slam , having previously won Wimbledon ( 2004 ) , the U.S. Open ( 2006 ) and the Australian Open ( 2008 ) . She may have won their previous three meetings but Sharapova was still forced to save three set points on her own serve in the second set before eventually prevailing . `` I had a really difficult opponent , '' added the Russian , who has won all four of her previous semifinals at the event . `` She really made me work for this match . A few ups and downs in the match but I 'm really happy to get through . '' The victory , which took two hours and 29 minutes to complete , was the second in successive tournaments for the Russian over Errani . The previous success came en route to winning the Indian Wells title earlier this month , a tournament which pushed Sharapova one place up the world rankings . In the men 's draw , Novak Djokovic 's conqueror Tommy Haas moved into the last four with a convincing win against 11th seed Gilles Simon . Germany 's Haas did not concede a break point to the Frenchman en route to a 6-3 6-1 victory . `` I played some good points when it came down to it , which I am proud of , and then served out the first set . I felt pretty comfortable after that , '' the 34-year-old former world No . 2 told the tournament 's official website . `` I used my chances right away in the second set and took that momentum . Again , I played the way I wanted to , using my all-around game and variety . I think I did that pretty well tonight . '' Next up for Haas is third seed David Ferrer , who came from one set down to defeat Austria 's Jurgen Melzer 4-6 6-3 6-0 . Spain 's Ferrer will be hoping to reach the final of this event for the first time in his career , having been a semifinalist in 2005 and 2006 . He also has more match wins than any other player on the ATP Tour this year , with Wednesday 's win over Melzer his 24th of 2013 . `` I was a little bit nervous in the first set and part of the second , '' said the 30-year-old Ferrer . `` But I tried to fight every point , to be focused and I had a good feeling in the final of the second set and of course in the third one .
