legit question: is Lily Z considered over the hill?
you need to ask Lily that
isn't there talks about her retirement within her circle? Even her family is talking about it if I recall.
I think life for USA based players is a tough one. If it wasn't for private resources, she would never be able to still live in the USA and be a Pro player. So many good players have left, because one can't even cover the basics living expenses as a player and with MLTT salary, it has helped, but she isn't getting any younger and can't live off others for ever. Making income (saving money) would probably be a major concern, as she is near 30.
She is probably still good enough to make the LA singles and teams spot.
Amy and a couple of others can be a threat to the spot.
If Lily stays on, and don't really make good income out of TT, it requires something like an Olympic dream or a home ground Olympic dream to put everything else aside.
I think for Lily to continue Pro, have high level table tennis and make an income, she should appear for her Pro A French club Saint Pierraise more, she currently has 0 outings this season, with Singapore's Zeng Jian taking up the international players role.
