Has anything happened to Whitney in her personal life since May 2019, or was it just a case progressing a bit too much too soon? No shame in losing today to a top 100 clay courter like SST (on clay), although 6-1 6-2 isn't ideal, but her record since RG 2019 is pretty almarming for a current top 100-150 player - she's now literally 1-16 against top 250 players since then, the only (top 250) player she beat in that period was Ellen Perez, and even that was 7-6 in the third, and that's also not including other defeats in that time to Loeb and Min (who were both outside the top 250). Most were in straight sets as well.
She's not even 18 and a half yet, so plenty of time to get back on track, but a bit concerning that the COVID break hasn't seemed to make any difference, and her results are like night and day compared to the player who beat Bencic and Haddad Maia en route to the Tyler W80 title 2 years ago, and obviously that great green clay run just prior to RG 2019.
