Q: (CNN) -- Maria Sharapova beat Li Na in three sets to defend her Italian Open title in Rome on Sunday in a bizarre match played in sometimes heavy rain and amid the distraction of football fans gathering nearby. Sharapova was 6-4 4-0 down but fought back to take the match into a deciding tiebreak -- after saving a match point at 6-5 in the third set. By the time the tiebreak came around, the rain was falling heavily, making conditions unplayable, and it even started to rain again when the players returned two hours later to complete the match. Sharapova eventually won it 4-6, 6-4, 7-6 (5) and the two players burst out laughing when they shook hands at the net.Maria Sharapova beats Li Na 4-6, 6-4, 7-6 (5) to win Italian OpenDeciding tiebreak delayed by 2 hours because of rain in RomeMen's final between Nadal and Djokovic postponed until MondaySharapova heads to French Open with two clay-court titles this year
