After his comprehensive third-round defeat to Feliciano Lopez at Wimbledon, it seems Andy Roddick's hopes of winning that elusive second Grand Slam are over.
Roddick, ranked No. 10, was crushed in straights sets by Lopez, the experienced Spaniard who is ranked 34 places below him on the ATP Tour.
And it was painfully clear on Centre Court that the Roddick of old, the 2003 U.S Open champion, will probably never return.
Here are four reasons why.
When Roger Federer's career started to blossom the same time as Andy Roddick's, it was clear the American would have to wait a while before he'd add to his 2003 Grand Slam triumph at Flushing Meadows.
So long as the above four are still on the ATP tour while Roddick is, it seems the three-time Wimbledon finalist will never win another major.
Another problem for Andy Roddick is his declining fitness in comparison to the likes of Nadal, Djokovic and even Federer, who is still a match for nearly every player on the tour.
A-Rod may not have been able to keep up his aggressive baseline play from earlier in his career, but nonetheless, his movement seems more passive nowadays, and he struggles more often when sprinting to the net.
Against Feliciano Lopez, it was evident Roddick has lost the energy of his younger days, giving up on more and more points, and subsequently giving up on his chances of winning another Grand Slam title.
The player universally considered "Mr. Serve," it seems Andy Roddick is in danger of losing that title.
In recent years, Roddick's ferocious, accurate, unstoppable serve has been in gradual decline, and now it seems he could get overtaken as the best server in the sport.
Against Feliciano Lopez, a player more noted for his willingness to play serve-and-volley and his single-handed backhand, A-Rod was beaten at all ends when it came to service games.
Lopez hit six more aces than Roddick, won more points on his first serve and was more reliable on his second serve.
It appears the American is in danger of losing the main weapon in his armoury, as a second Grand Slam title looks ever more elusive.
Whether it's due to his declining fitness, his shoulder injury before the French Open or any technical deficiencies, Andy Roddick is a player who seems to be getting more defensive year after year with his tennis.
Most of his game nowadays is played behind the baseline, as he seemingly waits for the opponent to make a mistake instead of dictating play himself, something that has been clear throughout Wimbledon this year, as well as his clay court season.
The A-Rod of today is a stark contrast to the all-or-nothing player five years ago—the man who would go all out to take control of the action and beat his opponent.
Nowadays it seems Roddick is a player who waits for his chance to strike. And unfortunately for the American, most players on the tour aren't too willing to give him that chance.
