Juan Martin del Potro has revealed that he will play in the Aegon Championships in June in preparation for Wimbledon.
The Argentine, who reached the final of Indian Wells before losing to Rafael Nadal last week, has praised the set-up at Queen's.
"I like to play on grass, and at the Aegon Championships you feel like you are at home. They provide some great facilities for the players and it's a very good tournament," Del Potro told the tournament's official website.
"Everything is made easy for the players - the locker-room is close to the courts, there is plenty of chance to practice on grass, and there are full crowds every day. It's a really nice tournament."
Andy Murray and Tomas Berdych have also committed to playing in London.
