Juan Martin Del potro will be playing at the AEGON Championships at Queen’s this summer.
The former U.S. Open champion will get ready for Wimbledon at Queen's where he will join defending champion Andy Murray
Del Potro said: "I like the surface, I’m not a grass-court specialist, but I’m improving.
"The Aegon Championships at Queen’s is an amazing tournament, very nice to come to, to play, to train and I will be there for sure trying to win my first title on grass.
"I think that if I play my best tennis I have a chance to win a Grand Slam on grass but it will be very difficult."
Runner up Jo Wilfried Tsonga will also be in the line up as he attempts to go one better than 2011.
Del Potro enjoyed a quarter final run at Indian Wells last week, losing to eventual champion Roger Federer.
The world number eleven is set to be back in action next week in Miami.
