Well, they both (Mona and Petra) have something in common, both floundering beyond belief. The pairing in doubles is most apt., for they lost in the lst round in doubles, as well. At least they are consistent in losing early.
Doubles are the only thing keeping her afloat these days.
Speaking of which, she's playing her R16 match today, teamed with Barthel against Hrdinova/Pliskova. Stream will be available around 18:00 CET.
Good luck Petra, God knows you need all the match practice you can get.
