Maria Sharapova made progress in her comeback Saturday even though her first title after a 10-month layoff was cut short by injury to her opponent.

Former No. 1-ranked Sharapova won her first tournament since undergoing surgery on her right shoulder a year ago when Jelena Jankovic was forced to retire in the first set of the Toray Pan Pacific final.

Sharapova was leading 5-2 when the seventh-seeded Jankovic took a timeout to have her right arm examined by the trainer.
