Birthday buddies finally meet in London

If you ever need a reminder of just how long Roger Federer’s been around, he practiced with one of his “birthday twins” in London Tuesday.

Chun-Hsin (Jason) Tseng, the 17-year-old No. 1 junior and French Open and Wimbledon junior champion was born Aug. 8 … 2001. That’s 20 years after Federer.

Tseng, who mixed in Futures events with juniors this year, is one of the youngsters invited to London every year to get a taste of the big time. 

He also has practiced with Marin Cilic.

And Wednesday, he got to hit with his idol, Kei Nishikori.

Comeback hipsters join forces in Fla.

A couple of aging hipsters (pardon the pun) got together in Florida.

Longtime rivals Bob Bryan, 40 and Nenad Zimonjic, 42 practiced together – and probably swapped stories.

Bryan had a hip surface replacement with an artificial joint Aug. 2 (don’t read the description on an empty stomach).

Zimonjic doubled him – pardon the pun. He had total bilateral hip surgery June 8.

The two have met … 57 times on the ATP Tour.

The Bryans went 1-8 during one stretch against Zimonjic and Daniel Nestor in 2008-09. To change something up in the 2010 Australian Open final, they changed sides – and won.

After break, del Potro offers an update

Juan Martin del Potro has been off the radar since the knee injury in Shanghai.

He reappeared on an Instagram video Wednesday.

And he seems to have emerged from a dark place, where he seriously debated whether he had yet another injury comeback in him.

“I felt like the world fell apart (Full translation here). “It’s a battle against doubts but without any doubt I will do whatever I can to be ready, to enjoy playing again and to leave these bad moments behind.”

No announcement about a return, but he promises to be in better touch.

Stosur already prepping for 2019

Samantha Stosur turns 35 in March. And her 2018 year-end ranking of No. 72 is her lowest in 15 years.

But if anyone thought she was winding it down, the Aussie is already back preparing for 2019 on the outside courts at Melbourne Park.

(As a side note, it’s ridiculous how little real vacation tennis players take. A week a year? Maybe two? Most average workers get more than that, and they don’t depend on their bodies for a living).

Stosur and countryman Joshua Eagle ended their two-year coaching relationship at season’s end.

But she hasn’t announced a new coach.

Tennis off-season means Maldives

Even if the tours are still going, it’s still the start of the tennis off-season.

You know what that means: selfies from the Maldives.

The remote chain of atolls, located southwest of the tip of Sri Lanka, has become a popular player destination over the years.

Last year’s highlight was Marin Cilic and Roger Federer randomly running into each other, and having a hit.

Caroline Wozniacki, Stan Wawrinka and Donna Vekic kicked it off this week.

Only one issue with this pic: how come the boys have frothy beverages, but the ladies are empty-handed?

Bertens caps off year with engagement

If a fellow is so in love he thinks your hands are this delicate, you should probably marry him.

And so Kiki Bertens, capping off a huge season, accepted boyfriend Remko de Rijke’s proposal in Bali.

“Ring too small, but that doesn’t matter at all!!” Bertens wrote on Instagram.

De Rijke, who turns 32 Nov. 6, is a former top junior whose career didn’t pan out. He pivoted into to a versatile one-stop shop; he is physio, fitness coach and hitting partner to Bertens.

Starting next year, de Rijke will split that job with Elise Tamaela.

Sania Mirza has a baby boy

Bucking the recent trend of tennis baby girls, Indian star Sania Mirza gave birth to a baby boy, Izhaan.

Her husband, cricketer Shoaib Malik, announced it on social media Tuesday morning, India time. He had to dash off to Dubai 24 hours later to play the first of a series of matches against New Zealand that run through December.

Mirza announced the pregnancy in April.

She said in May her priority after the birth would be to return to the court.

Because of a knee injury, Mirza hadn’t played since Sept. 2017. She turns 32 in April.

Peya tries his hand at TV commentary

Austrian doubles specialist Alexander Peya’s playing career is still going strong.

He’s the reigning Wimbledon mixed doubles champion with American Nicole Melichar.

And his doubles ranking sits at No. 17, as he and Nikola Mektic of Croatia qualified for the ATP Tour Finals last week.

But Peya has been out since Cincinnati with an elbow injury.  So last week in Vienna, Peya kicked back as Mektic played with Rajeev Ram, and tried his hand at TV commentary with ORF Sport.

He did get some practice in with Mektic, so it appears they plan to play London.

Kudryavtseva to add to tennis family

Add Russian Alla Kudryavtseva to the tennis baby watch.

The Instagram photo of Kudryavtseva and husband Dan indicates the arrival will be in December.

The marriage proposal came last November. The civil ceremony occurred in late July.

The formal wedding took place Sept. 19 in Lake Como, Italy.

By the official photos – strategically placed bouquets and all – it seems things had already progressed nicely by then.

Now 30, playing mostly doubles, Kudryavtseva last played at Wimbledon when she would have been a few months along.

She joins Elena Vesnina, Martina Hingis and Nadia Petrova in recent baby news. 

Halep to test back in Moscow

Hampered by a herniated disc, Simona Halep will test out the effects of a week of intensive treatment in Moscow next week.

Via Twitter, Halep posted photos of her workouts in the gym. She wrote she was leaving for Moscow Friday.

Halep obviously will be the top seed. But while the only other top-10 player entered is Karolina Pliskova, the field also includes Kasatkina, Bertens, Sevastova, Sabalenka, Kontaveit and other players who did well in Asia.

The Romanian hopes the extra prep will serve her well in Singapore. Coach Darren Cahill won’t be on hand.
