Maria Sharapova has played only four Fed Cup ties, but her presence on the court could make all the difference as Russia takes on holder the Czech Republic in the 2015 final at the weekend. The 28-year-old world No. 4 will likely face sixth-ranked Petra Kvitova and ninth-ranked Lucie Safarova, the left-handed duo who have led the Czechs to three Fed Cup titles from the last four editions. "It's a great way to finish off the year playing with two of the best players," said Sharapova, a five-time Grand Slam winner, who was sidelined with leg and arm problems from July to October. "It's definitely a very new experience, I've been part of the team on different occasions but never in the final." Sharapova returned to action at the WTA Tour Finals last month, where she lost to Kvitova in the semifinals — after losing to Safarova at the French Open in June. "I know how difficult an opponent they are and it will be a great challenge for me," said Sharapova, called up alongside 23rd-ranked Ekaterina Makarova, Anastasia Pavlyuchenkova (28) and Elena Vesnina (111). "We are coming into these finals as the underdogs," she added. Russian captain Anastasia Myskina said she was pleased to have Sharapova on the team, waving aside a decade-old rift between them over Sharapova's father. Equally high-spirited, the Czech team denied being the odds-on favorite. The two nations have met five times in the Fed Cup before but three of those meetings were between Czechoslovakia and the Soviet Union. The Czech team leads their head-to-head record with Russia 3-2, including a victory in the most recent encounter in the 2011 final in Moscow.
