Former world number one Saina Nehwal lifted the Indonesia Masters title as her Spanish opponent Carolina Marin retired-hurt during the first game of the summit showdown in Jakarta on Sunday.
Marin, the reigning Olympic champion and three-time world champion, twisted her right knee after landing awkwardly following a smash in the first game itself.
The Spanish shuttler was leading 10-4 before her discomfort and pain forced her retirement.
Saina was the runner-up in the 2018 edition of the Indonesia Masters and this is the first big success on the international stage after she tied the knot with fellow shuttler P Kashyap in December last year.
Carolina injured her right foot after a hard landing and, despite trying hard, she could not continue playing. Eventually, she decided to pull out of the match.
Saina did not make the best of the starts in the final match as her three-time world champion opponent raced ahead with a four-point lead in the first game. Carolina further consolidated her lead over the Indian shuttler as she was now leading the game 9-2.
With the first game scoreline reading 4-10 in Carolina's favour, the match was brought to a forced end.
With Carolina pulling out of the match, Saina clinched her first-ever Indonesia masters title.
In men's singles event, Danish badminton player Anders Antonsen defeated Kento Momota of Japan 21-16, 14-21, 21-16 in the final match to win the Indonesia Masters trophy.
