Caroline Wozniacki plans to join her boyfriend, golf star Rory McIlroy, in Augusta next week for The Masters.

Sadly for sport’s glamor couple, she won’t be bringing a Family Circle Cup trophy with her.

Wozniacki, the No. 2 seed, bowed out in the quarterfinals Friday night, dropping a 3-6, 6-4, 6-3 decision to 63rd-ranked Stefanie Voegele of Switzerland.

Voegele will face 2007 Family Circle Cup champ Jelena Jankovic in today’s semifinals, the undercard to the 1 p.m. showdown between Venus and Serena Williams.

Wozniacki, who won here in 2011, seemed in control early in the match, but got flustered as Voegele found the range on Billie Jean King Court and won the last five games to complete the upset.

“I thought I was very much in control at the start,” said Wozniacki, who was ranked No. 1 in 2011 and is currently No. 10. “I was taking the ball early and making her run. But she stepped it up in the second and third set. I definitely had my chances that I should have taken.

“Everything she went for went in, and when you play someone like that, you have to take the chances you get.”

Said Voegele: “My plan was to push her around.”

Wozniacki’s plan now is to practice on Daniel Island today and Sunday before heading to Augusta.

“I’ll watch (The Masters), do a lot of gym and fitness, and head home,” she said.

For the 23-year-old Voegele, today’s semifinal with former No. 1 Jankovic represents one of the biggest moments of her young career.

Jankovic, 28, won her 500th WTA Tour match Friday and has more than $13 million in career earnings. Voegele has won $684,457 in her career.

“I’m looking forward to the moment,” said Voegele, who upset 30th-ranked Julia Goerges in the third round. “I think I have to play the same aggressive style again.”

Jankovic made her second straight semifinal with a 6-2, 6-1 whipping of qualifier Eugene Bouchard of Canada and is eager to reclaim the form that made her No. 1 in 2008.

“I’m pretty happy with the way I played,” Jankovic said. “I played a young opponent with big potential. I was in control of the match and controlling the points.”

“Right now, I feel very motivated,” she said. “I have the hunger.”
