Our contributing blogger Omair dug into the world of Olympic stats and brought us the previews of the semifinals. Let's see the numbers behind the 2012 Olympic performances of our semifinalists for an insight into who has a greater chance to win. First up on the menu: Victoria Azarenka vs. Serena Williams.

Victoria Azarenka and Serena Williams will meet for the 10th time in their careers, most recent meeting coming on the very same lawns of Wimbledon just a few weeks ago, at the same stage of the tournament (in that match, Serena hit 24 aces, thus winning an entire set only with aces!). It was Serena who walked off victorious. Will it be different this time?

Azarenka fought hard to fend off the Angelique Kerber challenge in the quarterfinals, 6-4 7-5. Serena joined Azarenka shortly afterwards, thumping Caroline Wozniacki in straight sets, 6-0 6-3. This will be a rematch of their Wimbledon semifinal, where Azarenka put up a brave show, but lost in straight sets.

Williams has yet to lose a set in the 2012 London Olympics, while Azarenka has already lost a set in her first-round victory.

Let's have a look at Azarenka's and Serena's performance so far in the tournament.

Visiting Victoria Azarenka's official Facebook page for her hot InStyle magazine photoshoot pics, I came across this wonderful childhood photo of the world number one WTA player. A comment from Facebook user Hilal Abdullah perfectly titles this picture: "From holding a chimp to being a champ".

This is not the first photo of the little Belarusian that we've seen. Remember the one we shared last November, with the mini Vika holding tight to her racquet and looking upwards to her aspiring future? So sweet!

Do browse through our complete collection of childhood photos of women's tennis players. You will see many cute treasures!

On her official Facebook page, Victoria Azarenka shared these stunning photos taken for the August 2012 issue of the InStyle Russia magazine. The long-legged Belarusian is gracing the cover, while the inside feature contains even more beautiful photos. My favorite is the above picture with the 22-year-old in the peach pleated skirt.

Omair is known for his statistical contributions to Women's Tennis Blog, but as of Roland Garros he started doing post-Grand Slam awards, giving WTA players awards they deserved on the account of their performance. You will see how the tables are turning all the time – within just a month Serena improved from the Biggest Disappointment to Grass Empress, while Maria Sharapova downgraded from the Clay Queen to the Biggest Disappointment.

Serena Williams – GRASS EMPRESS

Serena Williams was coming off a first-round defeat at Roland Garros, her first ever first-round exit at Grand Slam, but she rebounded beautifully, reminding us that she still is the player to beat on grass. The American defeated three of the Top 4 players on her way to the Wimbledon 2012 title - Petra Kvitova in the quarterfinals (world No.4 and defending champion), Victoria Azarenka in the semis (world No.2 and reigning Australian Open champion) and Agnieszka Radwanska in the final (world No.3). To top that off, Serena went on to win the doubles title as well, with sister Venus Williams.

Agnieszka Radwanska – FINESSE QUEEN

In today's game of power and big hitters, in making the Wimbledon final Radwanska showed us with her crafty play and her court sense that there still is room for finesse players. She did what neither Petra Kvitova, nor Victoria Azarenka managed to do, i.e. take a set off Serena Williams. Before Wimbledon, Radwanska was the only member of the Top 15 never to have made a Grand Slam semifinal, but she went one step better at Wimbledon making the final and falling in three sets to one of the best grass-court players ever.

Acerena, that's how we can call Serena Williams from now on. In today's Wimbledon semifinal victory, the American fired 24 aces, the 24th in style, on the match point, that is actually 4×6 one whole set, bettering her personal best of 23 achieved only three rounds ago against Zheng Jie. Serena's total number of aces at Wimbledon 2012 up to the final is 85, while second-ranked in that department is quarterfinalist Sabine Lisicki with 35. Can Williams' serving impress you more? You bet she can! Today against world No.2 Victoria Azarenka, Williams hit those 24 aces without making a single double fault! I don't like using multiple exclamation marks, but I feel like using five at this point.

You remember that in our preview we mentioned that Azarenka's pre-semifinal stats were 9% better than Serena's on the net and 13% better on the receiving points won, but today the sixth-seeded Serena lifted up her level there as well, winning 71% to Azarenka's 73% on the net and 36% to Azarenka's 27% of the receiving points won. In winners to unforced errors differential Serena was brutally dominant, hitting 45 winners to Azarenka's 14, and 14 unforced errors to Azarenka's just 5 less. Final score: 6-3 7-6(6). Williams has now won her last eight matches against Top 2 players, in straight sets!

Moreover, the day before the semifinal, Acerena played two doubles matches alongside sister Venus, won them both to reach the quarterfinal, and today shortly after her win in singles, Acerena got back to the court and celebrated yet another victory with Venus, reaching the Wimbledon doubles semifinal where they will face top seeds Liezer Huber and Lisa Raymond. Every time the Williams sisters play doubles at Wimbledon, one of them wins the singles title. That tradition can very well be continued as Serena takes on first-time Grand Slam finalist Agnieszka Radwanska in the title match.

Actually, the third-seeded Radwanska was the only Top 15 player never to have been in a Grand Slam semifinal, but she cast that spell away at this Wimbledon and even reached the last match of the tournament in singles by eliminating Angelique Kerber 6-3 6-4. Hitting just six unforced errors in the entire match, Radwanska recovered from a 3-1 deficit in the first set to take five games in a row and win the set, while in the second set a sole break in the fifth game allowed Radwanska to establish herself as a victor over Kerber.

If Radwanska wins the final she will climb to No.1 in the WTA rankings for the first time. Given Serena's serving and experience, few of us believe that can happen, but who knows. Moreover, Radwanska was already the first Pole in the Open Era, male or female, to reach a Grand Slam semifinal, and now she is the first one in the final. (photos: © Neal Trousdale)
