Ekaterina Makarova retires at age 31

Ekaterina Makarova, who reached No. 8 in singles and No. 1 in doubles (just over 18 months ago), has announced her retirement. It was not unexpected; the 31-year-old Russian played just three singles matches in 2019, the last in Dubai nearly a year ago. She entered, and withdrew from, numerous tournaments in 2019. She is officially on the ITF's anti-doping retired list, dated Jan. 28, 2020. In all, Makarova won 14 doubles titles and three singles titles. Of those 14 doubles titles, three were majors; she was denied twice in the Australian Open final in a quest to own a "career Slam".

Former top-10 Bonder hits seniors circuit

American Lisa Bonder, a 1984 French Open quarterfinalist and a former top 10 player, debuted on the seniors circuit last week in Florida. Bonder, now 54, lost just four games in winning the singles title – in the 40s category. She went 2-1 in the 30s round-robin and teamed up with former pro, Jenny Klitch, to win the doubles title in the 50s. Bonder – listed as "Bonder-Kreiss" as a pro, and "Bonder-Kerkorian" in this seniors debut, has quite the history off-court. But clearly, once you have the skills, they never leave you.

No fine for Djokovic after umpire flap

According to tennis journalist Simon Cambers, no fine was issued in the wake Novak Djokovic's confrontation with chair umpire Damien Dumusois in the Australian Open men's final. Verbal and physical abuse violations both are subject to fines up to $20,000 Per the Grand Slam rulebook, verbal abuse is "a statement about an official ... that implies dishonesty or is derogatory, insulting or otherwise abusive." Physical abuse is" the unauthorized touching of an official, opponent, spectator or other person." Seems clear. Djokovic said he "didn't know" it was forbidden and said, smiling, that it was a "nice, friendly touch".

Venezuela home tie now a road trip

Next month's Group I Davis Cup playoff between home Venezuela and New Zealand has been relocated to ... New Zealand . The last three "home" Venezuela ties were held at the Miami-area Doral Park Country Club. A home tie in 2016 was moved to Peru. The ITF cited safety concerns. Their last true home tie was in 2016, in Caracas. This is the second move for the upcoming tie – the original location was the same "neutral" Miami venue. It seems the "Davis Cup hosting requirements" now are not met there, either. It's short notice, so New Zealand must find a venue.

Radwanska expecting to join the mom club

There are probably betting odds out there on a lot of the WTA's players, once they get married and retire from the sport. When will they make "the" happy announcement? The odds will get shorter soon enough on Caroline Wozniacki, who ended her career in Melbourne. But the latest is Wozniacki's pal Agnieszka Radwanska, who announced via Instagram that her little family is about to expand. Radwanska, who is still just 30 – younger than a lot of players out on the Tour – married Dawid Celt in July, 2017. He'll captain the Polish Fed Cup team this week.

Baby Sofia Kenin aimed for No. 1

One of the great bonuses of the new generation of tennis players is that there's so much video of them from a very young age. There's not much cuter than a baby Barty or a young Zverev hitting tennis balls. And, growing up in the tennis hotbed of south Florida, the precocious Sofia Kenin  – who won the Australian Open Saturday – got ample time to hang out with the stars - and have it documented. So when you're putting together a little documentary about her young self, there's plenty of great material to choose from. Here's one.
