The 135 mph serving makes tiebreakers a little easier for Andy Roddick who can utilise his killer serve to finish off grass court opponents at Wimbledon.

Roddick improved to 22-3 this year in tiebreakers, a win ratio that very few top players can boast to have.

"Obviously, being able to win cheap points under tense situations with my serve helps," revealed the fastest server in the world.

In the tiebreakers against Melzer at Wimbledon, Roddick won eight of his nine service points. On top of that he won more than 70 percent of his service points in the match and finished with 33 aces.

Serving with those statistics on the grass courts of Wimbledon, magnifies the advantage for big servers. Roddick was runner-up to Roger Federer at Wimbledon in 2004 and 2005.

"I feel like I can play better," Roddick said. "Every time I go out there, it's about just surviving. You know, no such thing as a bad win, so that's just the way you look at it."

Seeded sixth, Roddick is into Week 2 for the fifth time in nine years at Wimbledon. His opponent Monday will be No. 20 Tomas Berdych, who advanced by beating No. 12 Nikolay Davydenko 6-2, 6-3, 6-2.

Berdych has yet to drop a set through three matches, and he's 2-2 against Roddick, winning the last time they played.

Roddick will be prepared. This is his first Wimbledon with coach Larry Stefanki, who can draw from many years on tour when he prepares scouting reports and has revitalised Roddick's career.

Andy Roddick is considered one of Wimbledon 2009's favourites with the bookies, earning odds of 14/1 from Bet365.
