Well, this match could go either way. As a qualifier, Tereza will have the advantage of more match play this week, better knowledge of the on-court conditions and lots of self confidence.
Gavrilova is the last direct acceptance. She hasn't played a tournament in over a month but so far this year she has some good wins (Doi, M. Garrigues, Davis) and her worst loss was to Duque-Marino (#144).
Gavrilova, of course, was world junior #1 in 2010 and, at #143, is almost certainly under-ranked. Still, this is quite doable for a WTA-level opening round. Let's hope that Tereza takes advantage of it. Good luck!
