Maria Sharapova has played only four Fed Cup ties, but her presence on the court could make all the difference as Russia take on holders 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.
