Roger Federer seems to have recaptured his potent service game. This is what American tennis legend Andy Roddick thought when he watch the Swiss Master went toe-to-toe with Novak Djokovic in the finals of the Wimbledon Open a couple of weeks ago.

Federer, who reached but bowed out to Djokovic in five sets in his first ever Grand Slam finals since winning at Wimbledon 2012, showed everybody that father time is still years away after another masterful performance on the lawn of All-England Club.

Despite Djokovic's all-out assault, Federer managed to take the game to the limit by exhibiting a combination of precision and advanced tennis technique. But the surprising thing about Federer's play in the final was a better and stronger service game - which was not left unnoticed by his old rival Roddick.

"Best I've seen Roger serve since .......Damn it," the former Grand Slam champion said of Federer's improved or perhaps best ever service mechanics.

Roddick was one of Federer's fiercest rival during his heyday, as the two produced a number of epic games against each other, whether it's on grass or hard court. And if there's a guy qualified to scrutinize or recognize Federer, it would be Roddick who engaged in 24 head-to-head matches against the Swiss.

Though Roddick managed to only win three of those matches, the American never failed to give his best shot against the Maestro. The two met four times in Grand Slam finals with Federer winning all of them. However, the 2009 Wimbledon finals proved to be Roddick's shining moment against the best tennis player ever, as he courageously hanged for his dear life before eventually losing 5-7, 7-6(8-6), 7-6(7-5), 3-6, 16-14.

How Federer's improved serve will help him win sixth US Open crown?

Pete Sampras mentioned last year that it would be a wonderful thing for Federer to master wielding a big racket because it adds more power in his service game and ground attacks. After several months of trial and error, Federer appears to have controlled the big-headed racket, making him more competitive against younger hard-hitters in the game.

At the US Open, where the bounce of the ball remains faster, Federer has a chance to showcase his skills and dig deeper into the later rounds. Experience will be the Swiss' greatest weapon in the upcoming tourney, but his newly-found confidence in his racket would also add up to his chance of winning another crown in Flushing Meadows.
