At some point during Maria Sharapova's second-round match, I searched for "Sharapova" on Twitter for a reason I've since forgotten and was astounded at how many of the comments were about her grunting. It's not as if tennis fans don't notice the grunting, they're just so accustomed to it that there's no need to tweet about it. (And even then, we still do.) But there's a whole population that doesn't watch tennis and is only vaguely familiar with the grunting of Maria Sharapova, so when they flip on ESPN2 looking for Skip Bayless, they're stunned by the noise and feel compelled to share their feelings via social media.

All of that is a long way of saying that I searched for "Azarenka" on Twitter today to see what people were saying about her grunting. These were the first 11 results.

Eleven comments during a blockbuster women's semifinal involving Serena Williams and each were about the noise being emitted, not the beautiful play on the court.

Some stray thoughts before Friday's semifinal between Novak Djokovic and Roger Federer ...

• Only in England would a semifinal matchup between Djokovic and Federer be considered an undercard. But because hometown hero Andy Murray is seeking to become the first British man to win Wimbledon since 1938, the blockbuster semi between the rivals with a combined 21 Grand Slam titles will be played before a semi that features two men with none.

• This will be the sixth time in the last eight Grand Slams that the two players have faced off in a semifinal. Federer and Djokovic had defied statistical probability by appearing on the same side of the draw in 13 of the last 15 Slams. It was an especially harsh stroke of luck at this tournament given Rafael Nadal's second-round upset. Djokovic has won four of those five semifinal meetings, including at last year's U.S. Open when he saved two match points and came back from two sets down.

(AP)An international charity stands to make more than $150,000 if Roger Federer wins Wimbledon thanks to a bet made nine years ago by a now-deceased British man.

After a 21-year-old Federer won Wimbledon for the first time in 2003, Nick Newlife of Oxfordshire, England, bet approximately $2,000 on the Swiss youngster setting the all-time record for most victories at the tournament. He received 66/1 odds on Federer winning seven titles by 2019.

Newlife died in 2009 at age 59 and left the betting slip in his will to Oxfam, an international charity collective devoted to fighting poverty. The organization stands to make $158,056 if Federer defeats Novak Djokovic in Friday's semifinal and hoists the trophy after beating Andy Murray or Jo-Wilfried Tsonga on Sunday.

Graham Sharpe, who works for the British bookmaker William Hill, took the "unique" specialty bet in 2003. He said it's drawn a lot of attention, including from its prime subject.

Serena Williams advanced to her seventh Wimbledon final on Thursday, using a historic serving performance to defeat No. 2 seed Victoria Azarenka 6-3, 7-6 (6). She'll face Agnieszka Radwanska in Saturday's final.

The four-time tournament champion hit a tournament record 24 aces, the final one hitting chalk in the middle of the court on match point. That total also ties an all-time WTA record. That she was able to set it in a two-set match against a reigning Grand Slam champion is even more staggering.

The win comes five weeks after Serena suffered the worst defeat of her career -- a first-round loss at the French Open to lightly regarded Virginie Razzano. The loss brought upon the requisite "is Serena done?" stories. She quieted those fairly quickly with her six wins on grass.

Serena was once again dominant on her serve in the match, continuing the run she's been on at the All England Club. She won 94 percent of first-serve points in the first set, 76 percent in the second set and 73

Wimbledon's "predominantly white" clothing rule applies to the practice court too, as semifinalist Victoria Azarenka found out before her match against Serena Williams. The world No. 2 was wearing a yellow T-shirt while warming up for the semifinal battle. That's a no-no at the All England Club.

An official at the All England Club quickly reminded Azarenka of the rule and provided her a white shirt to wear over the offending yellow one. I wonder if they pulled that off a merchandise shelf or whether it's a loaner they give out to underdressed patrons, like when you go to The Palm and the maître d "suggests" you put on a sport coat.

Azarenka didn't look pleased to be making the court change. And she certainly wasn't feeling the tight arm holes on the shirt.

She issued no further complaint and wore the shirt for the rest of practice.

Azarenka shouldn't get rid of the T-shirt just yet. When the Olympics start at the All England Club in two weeks, players will be allowed to wear

Twice during his third-round match against Marcos Baghdatis, Andy Murray had tennis balls fall out of his pocket in the middle of a point. Those incidents led to two point penalties and forced Murray to ditch the shorts for a longer pair before he played in the second week of Wimbledon.

What was to blame? Poor ball placement in the pocket? Too much thigh-to-pocket friction? A lack of McEnroe-like short tightness?

According to Murray's outfitter, adidas, it was a combination of the three. [We work] closely with Andy on the design of all his kit and we believe the issues were the result of an individual technical error in the handmade pockets of those shorts," adidas wrote in a statement.

I appreciate how adidas conspicuously threw in the "handmade" part, as if that's going to make their screwup acceptable.

Murray switched to the company's longer Barricade Bermuda shorts and had no stray ball problems en route to Friday's semifinal matchup with No. 5 seed Jo-Wilfried Tsonga.

Last month, Mikhail Youzhny scrawled "sorri" in the red clay of Roland Garros to apologize to fans for his poor effort against David Ferrer. On Wednesday at Wimbledon, Youzhny was just as animated in his blowout loss -- this time to Roger Federer. He jokingly asked for help from royal box spectators Andre Agassi and Steffi Graf, mock celebrated when he won a point and, in his most memorable Centre Court moment of the day, let out a Pavarotti-like scream after netting a forehand return on a third-set break point.

The yell lasted more than five seconds and sounded more like an operatic crescendo rather than the Russian profanity it surely was. It was uncomfortable enough to draw camera reaction shots of both tennis and actual royalty. Only the Duchess of Cambridge seemed to be amused.

Who says chivalry is dead?

After Mardy Fish hit a line judge in the face with a 118 mph serve, his opponent, Jo-Wilfried Tsonga, immediately ran over to her to check on her condition.

The woman received some medical attention and had to be replaced but was reportedly fine after the beaning.

All in all, we're amazed this doesn't happen more but not at all surprised at the classiness of Tsonga.
