1. Rafa Nadal- Last Four Tournaments Played: Roland Garros [Fourth Round], Madrid [Runner-Up], Rome [Winner] and Barcelona [Winner].
The World No. 1 continues to lead the Power Rankings pile in spite of his recent brush with injury and failure to get past beyond the first week at Roland Garros 2009 due to his back-to-back victories at Monte Carlo, Barcelona and Rome.
With Wimbledon just round the corner and the point gap between him and his nemesis Roger Federer visibly narrowing down, Rafa has a lot at stake in the coming two weeks, squaring off not only against his professional rivals but also against his own physical self.
2. Roger Federer- Last Four Tournaments Played: Roland Garros [Winner], Madrid [Winner], Rome [Semifinalist] and Monte Carlo [Third Round].
The former World No. 1 has silenced almost every critic with his record equalling victory at the French Open completely satiating the raging GOAT debate.
The grass court season has always been one of Federer's forte and Wimbledon remains his favourite part of the tennis season; and now after losing last year's nerve biting drama in the final, Federer looks dauntingly determined to reclaim the Silver Cup like never before.
3. Andy Murray-Last Four Tournaments Played: Queens [Winner], Roland Garros [Quarterfinals], Madrid [Quarterfinals] and Rome [Second Round].
The British World No. 3 captured the Aegon Championship this week proving that his form has grown exponentially on grass, unlike a mediocre improvement on clay.
Last year seeded 12th at Wimbledon, Murray was a quarter-finalist before falling to the eventual champion Rafael Nadal; this year he will however be seeded third and considering his superiority in the green turf, will prove an altogether difficult opponent to square against.
4. Novak Djokovic-Last Four Tournaments Played: Halle [Runner-Up], Roland Garros [Third Round], Madrid [Semifinalist] and Belgrade [Winner].
The excellent run of form that Djokovic enjoyed prior to the French Open was hastily cut short at the Parisian clay by Phillip Kohlscrieber in the third round.
Playing well at Halle, Nole was pitted to be the favourite post Federer's withdrawal citing exhaustion and fatigue and winning it would have bolstered his chances playing at the All England Lawn Tennis and Croquet Club.
However, his unexpected loss in the finals to German Tommy Haas makes it obvious that Nole needs to put in more effort to get back to the scintillating showmanship he was previously displaying.
5. Juan Martin Del Potro-Last Four Tournaments Played: Roland Garros [Semifinalist], Madrid [Semifinalist], Rome [ Quarter-finalist] and Monte Carlo [Second Round].
The young Argentinian has done well in these past months, especially in the French Open where he gave a tough fight to the champion Roger Federer in the semifinals.
However, the clay season has ended and playing in the grass is totally unlike playing at clay, therefore Del P needs to fight hard against rivals whose playing strength might be greater in the greenery than in the slow red dirt.
6. Andy Roddick-Last Four Tournaments Played: Queens [Semifinalist w/o], Roland Garros [ Quarter-finalist], Madrid [ Quarter-finalist] and Miami [ Quarter-finalist].
The former US Open champion has improved a lot under the guidance of his coach Larry Stefanki and offering a solid proof of this fact was his performance at Roland Garros, an event which has always troubled him in the past.
A semifinalist at Queens last week, he was forced to retire in his semifinal against fellow American James Blake due to an ankle injury, which could act as a barrier preventing him from playing Wimbledon.
But, if his injury isn't by any chance serious, then Roddick with his new improved version and spectrum will hope to give a more than satisfactory performance at London.
7. Fernando Verdasco-Last Four Tournaments Played: Halle [First Round], Roland Garros [Fourth Round], Madrid [Quarterfinals] and Rome [Quarterfinals].
The Spaniard did not do well at the recently concluded Halle tournament falling prey to a lesser known Phillip Petzsner in the first round itself.
Whether or not, he has improved on grass will be tested in the course of the next few days, making Verdasco walk on the fire like he has never done so far into the season.
8. Nikolay Davydenko-Last Four Tournaments Played: Roland Garros [ Quarter-finalist], Madrid [Third Round], Rome [Second Round] and Barcelona [Semifinals].
The Russian made a good comeback from injury reaching the quarterfinals of the French slam and overall enjoyed a decent success in the clay season.
Grass, however is not his favoured turf and he has never performed well at Wimbledon; but so far, like always Davydenko remains a dark horse entering the fray.
9. Robin Soderling-Last Four Tournaments Played: Roland Garros [Runner-Up], Dusseldorf, Madrid [Third Round] and Rome [Second Round].
The Swede was a surprise package at the French Open when he caused the upset of the century by defeating the four time champion Rafa Nadal in the fourth round before finally ending the event as a runner-up to Federer.
Under the tutelage of Magnus Norman, Soderling has gained confidence ih his game and it's this confidence that will aid the 25 year old in addition to his game prowess at SW-19.
10. Fernando Gonzalez-Last Four Tournaments Played: Roland Garros [Semifinalist], Rome [Semifinalist], Barcelona [Semifinals] and Miami [Third Round].
The Chilean too found favouritism with the dirt as he reached the semifinals of all the three clay court events he played.
Will grass be a different story than clay or will Gonzo do equally well at Wimbledon; it's something that the next two weeks should elaborate.
Outside Looking In:
1. Jo-Wilfred Tsonga-Last Four Tournaments Played: Halle [Second Round], Roland Garros [Fourth Round], Dusseldorf and Madrid [Second Round].
The Frenchman hasn't displayed any solid tennis at any point in this season and Wimbledon looks like a perfect place to start anew.
2. Tommy Haas-Last Four Tournaments Played: Halle [Winner], Roland Garros [Fourth Round], Madrid [Second Round] and Houston [Quarterfinals].
The former World No. 2 captured Halle thereby giving one more demonstration of his comfort level in grass which should accentuate more over the course of the next two weeks.
