Agnieszka Radwanska's poor sportsmanship following her semifinal Wimbledon loss to Sabine Lisicki, is the latest case of WTA women behaving badly.
Lisicki came back from an 0-3 deficit in the third set to win at 6-4, 2-6, 9-7. She then approached the net for the customary handshake.
But instead of offering the traditional eye-to-eye congratulations, Radwanska zipped past Lisicki, turned her back and barely shook her hand.
So jarring was this gesture that it became a hot topic on Twitter. Howard Bryant, a tennis columnist for ESPN, tweeted his disbelief.
Matt Cronin, who writes for Tennis.com, immediately tweeted about the "cold handshake."
Of course Radwanska was disappointed about blowing perhaps her best chance to win a Wimbledon title. But that's no excuse for turning your back on an opponent after a hard-fought match.
Reeked of sour grapes.
The highest seed left in the tournament, Radwanska perhaps believed she was entitled to the win.
Whatever she felt, that was no way to treat a worthy adversary.
Serena Williams, winner of 16 Grand Slams and huge favorite, gave Lisicki a proper handshake and words of encouragement.
Kirsten Flipkens hugged Marion Bartoli after their semifinal match.
So what's up with Radwanska?
When asked about the slight in her post-match press conference, Radwanska responded via Fox Sports: "What should I do? Dance?''
No Aggie, you don't have to dance. Perhaps you could behave like Li Na did when she lost to you in the quarterfinals. Remember that nice congratulatory handshake and kiss?
Yet she disses Lisicki like that?
It's another example of catty behavior on the women's tour.
Seems silly considering this is 2013. This is 41 years after the establishment of Title IX. The WTA is celebrating its 40th anniversary. This week ESPN aired a documentary about Venus Williams' role in fighting for equal prize money for female tennis players.
Yet Wimbledon kicks off with two female icons publicly squabbling over who is dating who.
At the French Open we saw Spain's Anabel Medina Garrigues openly scuff new balls to gain an advantage against Williams. Girlfriend was cheating, on camera.
Who can forget Sloane Stephens and her brat rant about Williams to ESPN magazine?
Then we had Serena Williams weighing in on an Ohio rape case in Rolling Stone.
Last year, the dislike between Sharapova and Azarenka spilled over into the post-match trophy ceremony. Sharapova, apparently upset about another long Azarenka injury timeout, spoke sarcastically to the crowd. Sharapova said it was "unfortunate that Vika was extremely injured today and just couldn't really perform her best game."
John McEnroe recently complained about the love-fest happening atop the men's tour. McEnroe said via Sports Illustrated that he wished for a return to old-fashioned rivalries. He thought the men could go at it "a little more viciously."
Of course McEnroe meant going at it on the court, not in press conferences, at trophy ceremonies or via magazine interviews.
He certainly wasn't asking for a "talk to the hand" moment on Center Court.
Enough ladies. It's time to grow up; man up. Stop behaving badly.
