Tereza Valentova vs Sofia Costoulas prediction
Tereza Valentova will have designs on cracking the top 40 before the year is out.
The 19-year-old Czech is just inside the top 50 and was as high as 42 back in May.
Valentova will be aiming for a solid run in Athens and holds a 1-0 head-to-head advantage over world number 157 Sofia Costoulas.
The Bulgarian is two years older than her opponent, but has played just six tour-level matches so far and there’s little in the details to suggest she will provide the upset.
