Well, that shouldn't be too much of a problem for her, cause she plays many of these Central Asian tournaments where there are similar playing conditions. Not to mention that she played many junior events in places like India as well as pro events in Africa, whose conditions are not easily comparable to those in most other places that host tennis tournaments. Donna is definately not a player that gets tired easily.
Great to see Donna so confidently through to QR2, especially considering she faced an opponent that she's already beaten before - put a bit of unnecessary pressure on oneself into the equation and trouble is a heartbeat away. I'm guessing she'll face Lertcheewakarn next. Don't know much about her, but sensing she's a pusher, and that could be a tricky task for Donna. Hope I'm wrong
If Donna qualifies in MD, she can play against: Alexandra Cadantu (ROM,68), Magdalena Rybarikova(SVK,66), Galina Voskoboeva(KAZ,80) and Lesia Tsurenko(UKR,111)
I hope that she will qualifies and get Tsurenko than Voskoboeva in second round.
Good luck !!!
