It's semi-final time at the WTA Finals in Singapore and we're chatting with veteran tennis journalist Ros Satar of Britwatch Sports.

Ros joins the Lucky Letcord from Singapore, where she is covering the 5th and final Singapore edition of the WTA Finals.

We break down the week that was in Singapore, and chat about what went wrong for those who didn't reach the semis.

Other topics discussed:

Caroline Wozniacki's rheumatoid arthritis diagnosis and how the Dane could be a big inspiration in 2019.

Naomi Osaka's wild ride, how it ended and what she might do next.
