Andy Roddick is the latest player to confirm his attendance at the Queen's Club tournament in June where he will join the likes of Andy Murray and Jo-Wilfried Tsonga.
The 29-year-old is a four time winner of the event having claimed the title back in 2003, 2004, 2005 and 2007and is always at home when playing on the grass courts of Queen's.
The American has slipped outside of the world's top 30 after a run of injuries and some poor form, but he has shown glimpses of a recovery as he beat Roger Federer last week in Miami.
"I love coming back to the Queen's Club," Roddick told the BBC. "There's so much history there and it's one of my favourite tournaments on the Tour. It's hard to believe I've won a tournament as strong as this four times and I'd love to win it again."
Tsonga had already confirmed his entry in the tournament and is hoping to go one step further than last season when he lost in the final to Murray.
The Frenchman shocked Roger Federer on the grasses of Wimbledon last season and is hoping to achieve the same level of success this season.
"I know that I can beat everybody on grass, so why not?" said Tsonga. "I know on grass that I am a good player. I go to the net and I serve well."
Murray is likely to be the top seed when the tournament begins on June 11, while Juan Martin del Potro has also confirmed that he will compete in the tournament.
