MIAMI, FL, USA – Everyone needs a little bit of luck sometimes. For No.20 Timea Bacsinszky, she’s had one of the best athletes in the world cheering her on in Miami and it’s paid dividends.

Bacsinszky backed up her big win over No.2 Agnieszka Radwanska with another stunner just 24 hours later, beating No.5 Simona Halep, 4-6, 6-3, 6-2, to advance to the semifinals of the Miami Open on Tuesday. In the stands supporting her all week was Switzerland’s Lara Gut, the No.1 Alpine skier in the world, who just two weeks ago won the Alpine Skiing World Cup. The 24-year-old became the first Swiss woman since 1995 to win.

“She wrote me the Friday before, so it wasn’t official that she was going to be in Miami,” Bacsinszky told WTA Insider. “But she finished her competition on Sunday for the Crystal Globes, and she wrote me on Friday like, ‘Hey, it would be fun if I could come watch you in Miami,’ so I knew she was coming to Miami anyway. It was actually a big thing in Switzerland; no one knew where she was, and I was reading Swiss news headlines that were asking, ‘Where Has Lara Gone For Holidays?'”

“I finished my season last Sunday and it was important for me to have a break,” Gut told WTA Insider after Bacsinszky’s quarterfinal win. “I decided to come to Miami and I found out there was a tennis tournament. So I contacted Timea and she got me a badge. I started coming the first day and I got interested and she was playing so well that I came the second day and she was still winning. I was supposed to fly home yesterday but since she won I tried to stay here for one more day. She’s playing awesome and it’s really fun to watch.”

Bacsinszky and Gut first met in 2009 but have become closer recently after Gut began working with Bacsinszky’s manager. Gut was scheduled to leave for Switzerland after Bacsinszky’s win over Radwanska but she knew she couldn’t leave her friend out in the cold.

“Yesterday after Timea’s win I had to call Swiss Air to see if they could change my flight,” Gut said. “I could stay here one day longer because I’m supposed to leave tomorrow for training. So it’s going to be a bit stressful when I come home but it was more important to stay here and cheer on Timea than have more time to pack.”

“In Switzerland it’s a small country. We have a chance to meet other athletes. We have such strong athletes like Timea, Roger, Stan, and Belinda. We were still kids when we first met. It’s cool to see what she has done all these years and that she’s still improving.”

Getting the credential for Gut proved slightly more difficult than Bacsinszky expected. Switzerland may be a skiing-mad country, but trying to explain the situation in Miami proved a little tricky.

“In Switzerland, she can’t walk around, everyone knows her,” Bacsinszky said. “Here too, she didn’t want to attract attention. I know Lindsey Vonn is well-known, but the No.1 [skier] is at your tournament and no one knows it.

“When I asked for a badge for her at accreditation I said, ‘You know Lindsey Vonn?’ and they said, ‘Yeah, yeah,’ and I said, ‘Well, the girl who’s just in front of her in the rankings and just won the Crystal Globe is coming, so provide it now,” she said laughing. “Just Google her name.”

Bacsinszky will play Svetlana Kuznetsova on Thursday for a spot in the Miami Open final. After a slow start to the season after rehabbing from a bad knee injury, Bacsinszky has played herself into form, reaching her best result since the China Open final last fall. A title in Miami would boost her back in the Top 10. It’s all clicking for Bacsinszky and having a great champion in her box this week certainly hasn’t hurt.

“It’s funny to talk about sport and to like exchange what you feel during a race, what do I feel during a match,” Bacsinszky said. “We have so many things to talk about. It gives many, many new [perspectives], views on sports. It was really, really interesting for me. Yeah, lucky charm for sure.”
