Boserup retires, heads to grad school

American Julia Boserup, the 2008 Orange Bowl champion, might not quite have had the pro career she dreamed of.

Injuries were a mainstay. And she has officially called it a day, at 27.

But the next chapter is already beginning.

Boserup heads to grad school at the University of Chicago in September, after earning a psychology degree from Penn State in Dec. 2016 while she was posting her best results on court.

Boserupreached her career high of No. 80 in June 2017, at age 25.

Eight months later (although she didn’t know it then), she played her final match.

Little Alex meets Stuttgart

A new young tennis fan made an appearance at the Stuttgart tournament this week.

He is Alex, the baby son of longtime tour player Alla Kudryavtseva.

As it happens, Kudryavtseva lives in Stuttgart.

Alex won’t remember it, but he was at Wimbledon when he was barely more than a gleam. He got on the court, too.

Born Dec. 10, he’s already 4 1/2 months old.

This is a very cute kid.

And, interestingly, Kudryavtseva posted a photo of the 2008 Fed Cup team that came to Stowe, Vt. to play the U.S. All four are recent moms.

No Prague finale for Team Bucie

When Bethanie Mattek-Sands had another surgery on her knee earlier this year, her goal was to be ready for the end of April – and to partner bestie Lucie Safarova one last time at the clay-court event in Prague.

The American has just begun her on-court buildup, But Prague is only two weeks away.

After making a trip to Miami to meet with the Mladenovic clan last month, Kristina Mladenovic confirmed Monday that “Big Sascha” is officially on board.

Bajin joins a team that, let’s be clear, includes the entire family.

Younger Thiem hits the Futures circuit

Big brother Dominic Thiem is seeded No. 4 in Monte Carlo.

But younger brother Moritz is on his way. The 19-year-old is in the qualifying at a $25K ITF event in Santa Margherita di Pula, Italy this week.

He earned his first ATP points last September, only to have them erased by the new points system.

In this offseason interview, Thiem talks about how the kid progressed without him even realizing it.

“It was a big surprise. When I saw him playing, he was a completely different player,” Thiem said. “A year ago, he looked like a 10-year-old.”

And her daughter Olympia, 19 months, has made her commercial debut.

It was only a matter of time.

Mother and daughter star in a new Pampers commercial, which Williams showed on her Instagram account Wednesday.

They wear matching, Easter-hued ensembles (with Olympia wearing a “Cruisers 360 Fit” model).

“(It’s) the only diaper I’ve found that can keep up with @OlympiaOhanian and her wild moves,” Williams writes. “I never know what she’ll do next but I love it because that’s how babies learn and grow! “

Svetlana Kuznetsova ready to return?

Svetlana Kuznetsova, out of action since last September nursing wrist and knee issues, has been in Barcelona training on clay for a week.

Russian journalist Ilya Ryvlin reports she hopes to play Lugano next week. Not entered, she would need a wild card.

Currently ranked No. 111, a protected ranking would only be slightly higher than that as she’s lost little ground in the rankings during her time away.

Here’s a recent interview that has … a lot of interesting insight.

Kuznetsova is officially entered in Madrid (main draw only), the Rome qualifying and … the French Open.
