( CNN ) -- Agnieszka Radwanska has only lost to one player this season . It 's just that she has now been beaten by Victoria Azarenka an incredible six times . World No . 1 Azarenka maintained her complete dominance over her Polish rival with a 6-2 , 6-4 win at the Madrid Masters on Saturday . Azarenka will play former No . 1 Serena Williams in Sunday 's final after the American beat Czech qualifier Lucie Hradecka 7-6 ( 5 ) , 6-0 . Azarenka had already ended Radwanska 's title hopes this year in Sydney , Melbourne , Doha , Indian Wells and Stuttgart . Radwanska has won her other two tournaments and withdrew injured in Kuala Lumpur . Asked if she was looking forward to another chance to go up against Azarenka , the No . 3-ranked Radwanska replied : `` Yeah sure , maybe in a couple of months ! '' Australian Open champion Azarenka hammered 29 winners on the infamous blue clay in Madrid as she looks for her fifth title of the year , but she faces a very different task against Williams . Azarenka has a 6-1 losing record against the 13-time Grand Slam champion , although they have n't met since the Belarussian rose to the top of the world rankings by winning the Australian Open in January . `` I have always been competitive against her and she is one of the toughest opponents to play against , '' Azarenka said . `` It 's going to be a different story this time . '' Their last meeting ended in a 6-1 , 7-6 ( 5 ) win for Williams in the U.S. Open third round last year . Williams did n't face a break point in her semifinal against the big-hitting Hradecka and came through a tight opening set before sweeping through the second in 24 minutes . `` She served amazing in the first set , '' Williams said . `` I came through in tiebreak , and after that I was able to relax , make less errors and make some shots . I was more aware in the second set . I think that helped me . '' The 30-year-old Williams has n't lost a clay-court match this season after winning the title in Charleston last month . She will move up to at least No . 6 in the world rankings on Monday . `` I have been working really hard but I do n't want to stop at No . 6 and I want to continue to do better , '' Williams said . `` Victoria obviously has been playing this whole year so consistent , so amazing and just nearly perfect so I am going into the final with nothing to lose . `` She 's the top-ranked player and she 's going in there with everything to win . ''

Williams beats Czech qualifier Lucie Hradecka in straight sets for her 12th clay - court win of the season . The winner will move up to at least No . 6 in the rankings on Monday .
