- Either Lena has a chronic internal ailment (i.e., colitis, enteritis, Crohn's, or some type of lower abdomen issue) -- or she is once again dealing with 'Vukovitis'. Mental stress can indeed cause lower body pains. No matter... whatever is truly going on sucks. "Virus" excuse is getting a bit old -- and often -- at this point.
mandoist09-11-2026 - Ironically, Martina became a U.S. Citizen about the same time as the Orange Convicted Felon & Abuser was just beginning on his road to losing all Daddy's Millions!!mandoist09-11-2026
- "Another fresh start is in the cards." Thanks for the Humor!! I'm guessing this is the minimum one can do to keep all your sponsors hanging-on in perpetuity?mandoist09-11-2026
- Vukov is doing this to Lena... AGAIN!!!!! WTA's autonomous collective should be dismantled for allowing Vukov to re-emerge from his hand-slapping suspension. Just ask WTA employees how that's been going lately as they witness his continued verbal abuses. Women's Pro Tennis should start over.mandoist08-11-2026
- Can't help but suspect Vukov is back to his old self again. Thank you, WTA. Perhaps you can give them a "Battling Couple of the Year Award 2026" ??mandoist08-11-2026
- Wtf? Why is there no reason? And what about the men's?Bel08-11-2026
- One step by another step -- WTA continues to 'lose the plot'. Too many hi-tech microphones being installed at most venues!!! Remove them (especially those along the hallways, sidewalks, and pathways throughout the venues. Not to mention (most of all) remove the mic's from the Players/Coaches Box.mandoist06-11-2026
- Enough of her bullshit. Go marry someone.mandoist06-11-2026
- Don't you just love this young lady!? We fans often expect athletes to be supermen and superwomen, often forgetting that they WILL GET TIRED! I love Alex's perspective. Tiredness for an athlete should never be viewed as a negative, especially if you are healthy, taking care of your body and mental health and putting in the work. What a mature perspective. Good for you, Alex!Rapunzel05-11-2026
- Jess is absolutely correct! But the disrespect is a trait I have noticed in most of the Russian players. Mirra is good but very immature and lacks humility. Conceivable needs to get a handle on that!Rapunzel05-11-2026
