Novak Djokovic will lead a stellar field as The Boodles celebrates its 15th anniversary at Stoke Park from June 21-25.
Fresh from his history-making win at Roland Garros, Djokovic will be making his only grass-court event appearance before Wimbledon.
Rafael Nadal was confirmed to play but has been forced to withdraw due to an on-going wrist injury. However, Goran Ivanisevic will be returning following his visit last year.
Juan Martin del Potro, Nick Krygios, Alexander Zverev and Borna Coric are just some of the other players confirmed in a star-studded line-up.
Boodles founder and director Patricio Apey said: “We wanted a special line up for our 15th anniversary. We are incredibly privileged that Novak Djokovic has chosen to come every year since 2006 and will return once again to complete his Wimbledon preparations.
“We are also delighted to have former US Open champion Juan Martin del Potro back from injury and joining us again, along with some of the stars of the future in Zverev, Krygios and Coric.”
