Sharapova was up 5-2 at Ariake Colosseum when the seventh-seeded Serb took a timeout to have her right arm examined by the trainer. Jankovic returned to the court and lost the first two points of the eighth game before retiring.
“It’s disappointing,” said Sharapova, who had arthroscopic surgery to repair a rotator cuff in her right shoulder nearly a year ago. “It’s toward the end of the year and there are a lot of injuries so I wish Jelena a speedy recovery.”
It was Sharapova’s first win since Amelia Island in April 2008.
Sharapova won her first tournament as a professional at the Japan Open in 2003 and won this tournament in 2005, defeating Lindsay Davenport in the final.
Jankovic got off to a strong start, breaking Sharapova’s serve in the first game and taking a 2-0 lead. But Sharapova fought back and took control of the first set when she broke Jankovic to go up 4-2.
“She started off so strong,” Sharapova said. “But it’s my second final of the year so I wanted to play strong. I played well all week so I felt I could give her a good match.”
Sharapova also reached the final in Toronto in August, losing to Elena Dementieva.
“It’s exciting,” Sharapova said. “We put in so much work and to be able to go out and compete in front of thousands of fans is great. You realize what a gift it is to hit a tennis ball.”
