Halep, whose match began on Wednesday but was halted because of rain with Pavlyuchenkova ahead 4-3, returned to close out a three-hour battle during which she required treatment for what appeared to be blisters on the bottom of her right foot.
The Romanian world number one will have a quick turnaround as she is set to cap the evening session with a battle against seven-time Grand Slam winner Venus Williams, who will also not be fully rested after beating Sorana Cirstea 7-6(4) 6-4 in a match that was postponed from Wednesday.

"I'm little bit dead, to be honest. It's a long time since I played my last match at Wimbledon. I will try to do my best to recover and fight next match," Halep said in her on-court interview.
"She's a champion and it's always difficult to play against her. On hard courts, it's more difficult. I will try to enjoy it and to have a nice atmosphere again."
