Konta through to quarter-finals
Briton won 5-7 6-4 6-0 against Kvitova
Faces Andrea Petkovic or Ekaterina Makarova next
Monica Puig beat Caroline Wozniacki 4-6 6-3 6-4
Agnieszka Radwanska beat Eugenie Bouchard 6-3 6-3
Another big scalp to add to a collection that already includes Garbine Muguruza, Simona Halep, Venus Williams and Roberta Vinci for Johanna Konta.
Many apologies for the loss of pictures from Eastbourne for some time during that third set. I hope you managed to catch the last couple of games when they returned and will join us tomorrow to see if Konta can make the semi-finals.
Bye for now.
Johanna Konta speaking to BBC Sport: "There are not words big enough to describe the support you the crowd have shown me, I really appreciate it from the bottom of my heart.
"Both of us were playing at a really good level in parts and struggling to keep that up in others and I think I just managed to string a few points together today.
"I am really happy that I was able to maintain my level as well as i could.
"Both Makarova and Petkovic are world-class players. I'm going to work on recovering now and getting ready for whoever I play."
