( CNN ) -- Top seed Gael Monfils saved a match point before edging past American John Isner to reach the final of the Legg Mason Classic in Washington on Saturday . The 24-year-old Frenchman , who has won three career ATP Tour titles but only one outside his native country , now has an opportunity to double that statistic after winning 6-4 3-6 7-6 in a match that finished at 01:15am local time following two rain delays . `` It was really tough to deal with -- to go on court then come back again . The weather was just like Wimbledon , '' Monfils told the official ATP Tour website . The greatest match in tennis history . He added : `` I have had a tough year . I had an injury and a new coach , so to come up strong again feels good . '' Monfils will face Czech Radek Stepanek , the oldest player in the world 's top 100 , in the final . The 32-year-old Stepanek , world-ranked 54 , sealed his place with a comfortable 6-3 6-3 success over American Donald Young . `` It has been a year and a half since I was in a final , so definitely I 'm very pleased about that , '' said Stepanek , who has won four career titles but has not reached a final since losing to Andy Roddick in Brisbane last year . Meanwhile , top seed Vera Zvonareva will face third seed Agnieszka Radwanska in the final of the WTA Carlsbad event in San Diego , California , but both players had to come back from dropping their opening sets to progress . Russian Zvonareva was pushed all the way by former world number one Ana Ivanovic of Serbia , taking two-and-a-half hours to claim a 5-7 6-4 6-4 success . Meanwhile , Pole Radwanska looked to be heading out against second seed Andrea Petkovic . However , the German was then hampered by a stomach virus , and Radwanska fought back to progress 4-6 6-0 6-4 . `` I ate something wrong for lunch . I originally thought it was just a lack of energy , so I had a banana and thought it was going to get better , but actually it felt much worse , '' Petkovic told the official WTA Tour website . Radwanska , who has been suffering from a shoulder injury , last reached a final when losing to Svetlana Kuznetsova here last year . Meanwhile , Petkovic will move into the world 's top 10 for the first time in her career on Monday , replacing Australian Samantha Stosur , despite her defeat .
