LONDON, Great Britain – Not bad for your Grand Slam debut. At 24-years-old, No.225 Julia Boserup qualified for her first major at Wimbledon and is into the third round after beating Tatjana Maria and advancing after Belinda Bencic retired in the second round. It’s been a heady week and a half for the American, who has already had to change and extend her accommodations multiple times as she prolongs her unexpected stay in London.

And she’s doing it all while trying to balance the best week of her career – and an Excel spreadsheet or two.

“I go to Penn State Online and I graduate in December,” Boserup said. “I’m studying psychology with a minor in finance. I have homework due in two days.

“I’m taking an accounting class and I have spreadsheets due on Sunday. I have a day off tomorrow. I already told my coach that I’m going to be sitting down and working on school. Me and Excel.”

The California native shares dual citizenship with Denmark – much to the delight of Danish reporters at Wimbledon who are still smarting from Caroline Wozniacki’s early exit. Her parents are Danish and she has family in Copenhagen, which operates as a convenient training base for her when she’s in Europe.

“My dad emigrated to the US when he was eight years old because his dad wanted the American dream, so he moved to the US,” Boserup said. “My mom was on vacation in California when she was 25 and she met my dad and they got married and she moved to California.

“But my older sister went to business school and met the only Danish guy there and married him and moved there. We’re all like, ‘Wrong direction!'”

Boserup started playing tennis when she was six years old and her first coach was the legendary Robert Lansdorp, who also taught the likes of Lindsay Davenport and Maria Sharapova how to hit their big, powerful shots. You see the same style of game from Boserup, who says grass is her favorite surface. At 13 years old she moved to Florida to work with the USTA and moved back to California when she turned 18. A year after winning the Orange Bowl in 2008 – she beat Christina McHale in the final – she opted to turn pro.

But injuries derailed her development. In 2012 she suffered stress fractures in both her feet and nursed a back injury on and off for two years. She has never been ranked higher than No.174. So why did it take so long for her to make the main draw of a Slam?

“It’s a good question and it’s a question I ask myself sometimes,” she said. “I think I’ve put a lot of work into it and sometimes you just have to be patient. I was injured a lot and it’s been a lot of stops and starts. In the big moments it has served me well. Going through those challenges has helped me.”

So could this be the spark that gets her on a path towards the Top 100? This is where Boserup’s maturity is most evident.

“It’s great that I’m in the third round of a Grand Slam, but for me what I’m most excited about is developing my tennis,” she said. “I’ve worked with my coach for three-four months now and everyday we try and get better at little things. That’s really made me get more excited to play. After this I’m still going to play a $50k. One week doesn’t change everything.”
