Lertcheewakarn's game transitioned really badly to the main tour. :-( She was never a clean striker of the ball, but she took it extremely early, almost like a half volley from the baseline, it worked for her as a junior but on the main tour she did not have the consistency, and her technique looked quite bad. I hope she is living a good life now, she still had an amazing experience and was able to play two grand slam main draws.Are you thinking of Noppawan Lertcheewakarn? Because she's now a police officer.
But Luksika Kumkhum played a full schedule (albeit lost most everything) for the first half of 2019, and seemingly picked up an injury.
Luksika has an exciting and fun game to watch. I hope she can get into the groove again and bring her flashy tennis back to the top 100. However her fitness and motivation are always suspect. As I recall, she turned down an opportunity to enter the main draw of the US Open one year for no particular reason. She seemed to get burnt out by tennis and never really put together an ambitious schedule.
