6-0 5-2 - brilliant from Dart! Really aggressive play with intent. Fruhvirtova definitely hasn't shown her best, and going down 6-0 3-0 is a massive hole to climb out of but she has shown some good points, so I wouldn't call this over. Dart has a few good wins lately over Svitolina, Konjuh and Kanepi, but she's still not a big match player - maybe those matches will at least have helped with this one. She doesn't have great clay prowess, so even playing the youngest Czech on the team, I think she's probably felt little pressure in this match so far. Now will be the real pressure - I wonder if she can keep it together, or if her form will dip and Fruhvirtova will play freely. You must feel huge pressure as a home player down such a score though, with the crowd wanting you to come back. She's also so young that she's not used to these tour type scenarios...
Edit: 6-0 5-3... Fruhvirtova serving to stay in the match after breaking Dart's serve to keep the rubber alive.
Edit 2: 6-0 5-4... Dart serving for the match again. It seems she isn't so good at closing a match on serve, and then with 2 MP hits a flurry of UEs and a poor drop shot (she did hit 1 thunderous backhand winner, too). At 6-0 3-0 this exact momentum shift happened which you could just feel watching the match. Any tightness from Dart and she will hit an error, even a marginal one. If she can close this out now it would be ideal as I think Fruhvirtova will be in the driving seat if this goes to a 3rd with a home crowd behind her and the damage of the 6-0 first set erradicated.
Edit 3: 5-5... You could tell this was coming I think I'm going to take a break. Typical swing of momentum at this point in the match. From 5-2 up you'd expect to win a service game and if servicing is an issue then break the opponent as you're not having to deal with your nerves on serve. Not the case unfortunately and somehow this could be going to a 3rd unless Dart can shake off her nerves immediately.
