SINGAPORE - Martina Hingis has hung up her racquets and retired after reaching the semifinals of the BNP Paribas WTA Finals Singapore presented by SC Global.

Hingis officially made her announcement on social media on Friday, after advancing to the last four with partner Chan Yung-Jan at the WTA Finals.

"Now that the cat is out of the bag, here we are for the third, and final time," Hingis wrote on Facebook, referring to previous two retirements. "Looking back now, it's hard to believe that almost exactly 23 years ago I made my professional debut. The years that followed have been some of the most rewarding years of my life, both personally and professionally, but I believe the time has come for me to retire, which I will be doing after my last match here in Singapore.

"This isn't goodbye. As history shows, I haven't been able to stay away from tennis for long in the past, and I am looking forward to seeing what new opportunities lie ahead of me. I believe the best is yet to come and will continue to share my experiences with you!"
