Andy Roddick

Roddick has immense power and great court craft, which makes him one of the title favourites.

Age: 21

Lives: Boca Raton, Florida

Plays: Right-handed, double-handed backhand

Grand Slam titles: One (US Open 2003)

Wimbledon record: 2003-semi-finals, 2002-third round, 2001-third round

The US Open champion is primed to launch his bid for the Wimbledon crown after winning his second successive grasscourt title at the Stella Artois Championships.

His decision to hook up with Andre Agassi's former coach Brad Gilbert 12 months ago proved to be a masterstroke as the former top-10 player has managed to harness Roddick's immense power with greater court craft to create a grand slam champion.

A thunderbolt serve — measured at a record 153mph (246.2 kph) at Queen's Club last week — and a clubbing forehand could give Roddick a memorable Fourth of July celebration.
