Fourth seed Halep’s 6-2, 7-6 victory over the German sets up a repeat of the Madrid Masters final last month, in which Sharapova came out on top.
The Romanian knows she will have to be at her best to pick up her first Grand Slam title but is determined to avenge her disappointment in Spain.
It’s a story that it’s not the end but the beginning of something really, really beautiful, hopefully
“I feel amazing, it’s incredible that I will be in the final. She played a very good game but I think I was just a little bit stronger,” Halep said.
“I know Maria will be very tough. We played in Madrid so maybe it will be revenge but I will do everything I can on the court and who knows.
“I have to play my game, be aggressive, open up the court, play the angles and do my best and hopefully it will be a good match.”
Meanwhile, Petkovic insisted that she could take a lot of positives from her run to the French Open last four.
Asked how she would report on her Roland Garros campaign if she were a journalist, Petkovic replied: “If it was my story, I would definitely tell it as a positive story, but also a story that showed me what I need to work on.
“It’s a story that it’s not the end but the beginning of something really, really beautiful, hopefully.”
The German added: “I gained a lot of belief in myself as a player again and the stages where I can get to. Because I’m here, I’m in the semi-finals, I was in the semi-finals, and I didn’t play my best tennis and I’m in the semifinals.
“I have still so many things to improve on and I was here at the semi-finals. So there is a long way for me to go. I have a good five or six years that I can keep improving.
“So I’m very positive with my career now.”
