Just 29, Ana Ivanovic is done with tennis.

“I got off to a fast start, because I knew she was a really tough opponent,” Serena said of the former world No. 8 and Rio Olympics gold medal winner in doubles. “I didn’t want to start off slow, and so I tried to get some momentum. That’s all I could do today.”

Jelena Ostapenko won a wild one Monday in Cincinnati.

Ana Ivanovic is married!

Strong field with four Top 10 seeds, and all seeds are ranked in Top 20…Potential tough starts for (1) Radwanska vs. Vandeweghe, (3) Halep vs. Safarova, and (2) Kerber vs. Peng…Wildcards went to Radwanska, Kvitova and Brits Naomi Broady and Tara Moore…

Translation: “The other non-divas on tour would love to have my year. Because they’re weak tea. But as Ricky Bobby said, ‘If you ain’t first, you’re last.'”

Venus Williams went 1-1 Monday at the Rome Masters, winning in singles but losing in doubles with her sister Serena.

As Ray Moore might say, ‘There are a lot of attractive ladies out there — umm, competitively attractive…oh crap, I’ve done it again.

What, too early for Maria jokes?

History has already been made in Dubai this week as for the first time ever at a WTA event no seeds won a match.

Let’s play “Guess Who Got the Appearance Cash?” with Venus as the top seed, and the No. 62-ranked Doi seeded second…No Top 10 seeds in the field…Remove Venus, and this would essentially be an ITF-level field…Potentially tricky starts for (8) Riske vs. the Croat riser Vekic, and (2) Doi vs. the lesser Pliskova…Wildcards stayed in-country to Chinese-Taipei’s Hsu Ching-Wen, Lee Pei-Chi and Lee Ya-Hsuan…

Nigel Sears, coach of Ana Ivanovic, collapsed during her match Saturday night.

Former champions Victoria Azarenka and Stan Wawrinka headline action Saturday at the Australian Open.

“Just heard she has some big — a big serve and big shots, yeah,” said Azarenka, who admitted she knew little about her opponent.

“She had confidence,” said Halep, who was not brimming with such. “She had three matches here already in the quallies. Yeah, she didn’t have fear…But I think I let her play her best tennis. I didn’t hit very strong and I didn’t hit with good strength…I had many problems in this period before coming here, so I can say that I am a little bit down mentally because I was very sick home. Then I came here with Achilles again. So it’s tough to be positive, 100%, and try everything.”
