For the second year in a row, Roger Federer is on course to equalize Pete Sampras’ record of seven Wimbledon titles. Defending champion Rafael Nadal is also through to the second week as he goes for his third French Open-Wimbledon duo. While Novak Djokovic, the hottest player this season, is in great form through three matches.

The world’s top three players are still the ones to beat heading into the round of 16 while world number four and hometown pick Andy Murray is also alive with an outside chance. Here’s a review of the past few days and a look at the rest of the tournament.

Federer has looked superb through the first three rounds of play. The Swiss dominated his third round match against a less than 100% David Nalbandian who’s had his number previously.

In the fourth round, Federer takes on Mikhail Youzhny. Federer has won all ten of their prior meetings and the Russian has never been beyond the round of 16 at this event.

David Ferrer tied his best showing at the All England Club by reaching the round of 16 and will face Jo-Wilfried Tsonga who was a quarterfinalist last year. The winner of that contest will probably battle Federer in the quarterfinals.

After straight sets triumphs his initial two matches, Djokovic had to bear down against Marcos Baghdatis to move on in four in the third round. On Monday, Djokovic meets Michael Llodra in the fourth round. Although Llodra is sensational on grass, he should be no match for Djokovic.

Eighteen year old Australian qualifier Bernard Tomic is the unforeseen name in the second week. In the first round, Tomic took down veteran Nikolay Davydenko. Next, he erased a 2 set to love deficit to topple another veteran Igor Andreev.

In the third round, Tomic stunned an ailing Robin Soderling in straight sets. The teenager clashes with veteran Xavier Malisse in the round of 16. The one left standing will probably see Djokovic in the quarterfinals. Consequently, a Djokovic-Federer semifinal seems a done deal.

Although Nadal was pushed his first three rounds, the Spaniard still dispatched his opponents in three sets. Juan Martin Del Potro was also tested in his second and third round matches by Olivier Rochus and Gilles Simon respectively but came through. As a result, the anticipated duel between Nadal and Del Potro will occur in the round of 16.

Since Del Potro’s return from wrist surgery, the two only tussled once at Indian Wells. Del Potro has improved considerably since that meeting. Yet, with his previous success on this surface, Nadal will squeak by.

With three time Wimbledon finalist Andy Roddick’s shocking exit in the third round to Feliciano Lopez, Mardy Fish is the sole surviving American. In his maiden fourth round showing at the All England Club, Fish collides with 2010 runner up Tomas Berdych.

Berdych and Fish have never played. Considering his 2010 breakthrough, Berdych has underachieved this year. Therefore, Fish has a tremendous opportunity to cinch his primary quarterfinal at Wimbledon where he will stare at either Nadal or Del Potro.

Twice a quarterfinalist at Wimbledon, Lopez encounters Lukasz Kubot in the round of 16. The 29 year old qualifier in his second main draw at this tournament ousted Arnaud Clement, then Ivo Karlovic and subsequently upended Gael Monfils in the third round.

With Murray’s erratic performance so far, his fourth round rival Richard Gasquet should be able to capitalize. However, twice, Roland Garros in 2010 and Wimbledon in 2008, Gasquet blew a 2 set to 0 lead against the Brit. That is a gargantuan psychological hurdle for Gasquet to overcome. As such, Murray should make it to the quarterfinals.

Murray prevailed in all four meetings against Lopez and appears to have a comfortable road to the semifinals. The question is whether Nadal or Del Potro will be his adversary.

Similar to the French Open, the top four players have a good chance of colliding in the semifinals. With Federer ending Djokovic’s perfect season, the latter will be looking for revenge. Djokovic is hungry for this distinctive prize which can work in his favor or his detriment.

On the other hand, Federer has the pressure of wanting to make history. The same applies to Murray with his nation hoping to claim its home trophy for the first time since 1936. Nadal is playing with fewer expectations which sets up the perfect scenario for him walking away with the championship for the second straight year.

After one week of play, the cream of the ATP has risen to the top at the Australian Open.   Although some had a tougher road than others, eight of the top seeds are still in the hunt.  Here’s a look back at the tournament’s key moments to date.

In the first round, Igor Andreev’s forehand gave world number one Roger Federer all sorts of headache.  After stealing the first set, Andreev was just one forehand winner away from serving for a two set to one lead.  When Andreev’s shot sailed long, so did his opportunity at an upset.  Thereafter, Federer cruised through his matches.

Another difficult challenge lays ahead for Federer in the fourth round in Aussie Lleyton Hewitt who will have the support of the crowd.  Still, Federer is favored in that match.  Should Federer advance, his tasks gets more complicated since he could face Nikolay Davydenko in the quarters, a man who has beaten him their last two meetings.

While Fernando Verdasco, a semifinalist last year, struggled through his first round match then benefited from a retirement his last round;  Davydenko, his fourth round opponent, has been in peak form through three rounds.  If Davydenko moves on to the quarterfinals, Federer’s streak of 22 consecutive majors semifinal will be in serious jeopardy.

An astounding fatality in the first round was French Open finalist, Robin Soderling. Playing Marcel Granollers ranked 113, Soderling let a two set to none advantage evaporate.  Current U.S. Open champ Juan Martin Del Potro who has been dealing with a wrist injury also made an early exit. After defeating James Blake in a thrilling second round match, in the fourth round, Del Potro fought hard but came up short against Marin Cilic in another five setter.  Cilic who has now gotten to the quarterfinals in the last two majors will battle Andy Roddick.

Although Roddick has been pushed with each passing round, he’s had the answers.  After straight sets wins in rounds one and two, Roddick required four sets against Feliciano Lopez, then five versus Fernando Gonzalez, the Australian Open 2007 finalist and his coach’s former pupil. If Roddick aces the Cilic exam, it will be either Rafael Nadal or Andy Murray his next nemesis.

Despite minor blips, Nadal, the defending champion, has been in his best shape since the French Open loss.  After routine victories the first two rounds, Nadal needed four sets against Phillip Kohlschreiber and Ivo Karlovic who are higher caliber players.  Nadal will clash in the quarterfinals with Andy Murray. Thus far, Murray has come through without dropping a set. If their 2008 U.S. Open meeting is any indication, this quarterfinal duel will be a great one.

When Mikhail Youzhny retired in the third round, for Lukasz Kubot it became a good news and bad news scenario. For the first time, 27 year old Kubot made it to the fourth round at a major. To his chagrin, Novak Djokovic will be his subsequent adversary. It is unlikely that Kubot has any weapon which will trouble Djokovic.  However, the same does not apply to Jo-Wilfried Tsonga who could be Djokovic’s counterpart in the quarterfinals.  Tsonga leads their head to head 4-2.

For Tsonga, the 2008 Australian Open runner-up, the primary order of business will be taking care of Nicolas Almagro in the fourth round.  In the third round, Tsonga put down Tommy Haas.  With Almagro’s five titles all on clay, Tsonga is an overwhelming favorite in that match.  So a repeat of the 2008 Australian Open final may be one match away.

So who will be the eventual champion?  With their take no prisoners performance so far, Davydenko and Murray have the edge. However, of the guys remaining with a legitimate shot at the title, Davydenko is the only one who has yet to make it to the final of a major. Therefore, the riddle is whether Davydenko can defeat both Djokovic and Federer in a best of five match to reach the final.

For his part, Murray will have to knock out Nadal and possibly Roddick to get to the final.  The Scot has the talent, so Murray is hoping with the off season he exorcised last year’s majors demons.

Ultimately, it may be another case of those who’ve been there before hoisting the trophy again.  Thus, Federer obtaining his 16th major or Nadal his second straight Australian would not be unexpected.

In the men’s doubles in Melbourne, the second seed, Mike and Bob Bryan, beat Mark Knowles and Mahesh Bhupathi, the third seed, 2-6, 7-5, 6-0 to win their third Australian Open title.

Knowles and Bhupathi dominated the first set, breaking at love to take a double break lead. Throughout the second set, Mark and Mahesh had multiple break chances, but failed to seize any, as the Bryans held firm. As Knowles served to send the set into a tiebreak, he double faulted and missed an easy volley to give the Bryans double set point. When Bhupathi tracked down a spectacular lob from his opponent and dumped the next stroke into the net, the Bryans equalized the match.

In the third set, the Bryans shifted to a higher gear. After holding serve, Mike and Bob had double break point and converted with a lob for a winner. On cruise control, the Bryans broke at love to secure the ultimate set and the championship. World number one, Daniel Nestor and Nenad Zimonjic were upset in the second round by Oliver Marach and Lukasz Kubot. That team then fell in the quarterfinals, ousted by Bhupathi and Knowles.

A day earlier, Venus and Serena Williams took the women’s doubles title by defeating Ai Sugiyama and Daniela Hantuchova 6-3, 6-3. After trailing in the first set 3-0, the Williams’ won six consecutive games to seal the first set. The second set was very competitive with the teams trading breaks back and forth. Finally, in the eight game, the Williams’ captured the lead and never relinquished it. A holder of the other three major titles in doubles, Sugiyama was denied the completion of the career doubles slam. Sugiyama and Hantuchova, seeded ninth, knocked out the number one seed, Liezel Huber and Cara Black, in the quarterfinals. In a reversal of last year’s Wimbledon, the siblings took both titles. However, this time, it was Serena holding up the singles trophy. Moreover, Venus deserves a great deal of praise for sticking around and playing so well after losing in the second round in singles.

The mixed doubles winner has yet to be decided as Sania Mirza and Bhupathi will play against Nathalie Dechy and Andy Ram.
