Top-10 star John Isner will complete his Wimbledon preparations at The Boodles exhibition event at Stoke Park in June.
The 6ft 9in American has confirmed he will appear in the eight-man event at the Buckinghamshire venue from June 19-23.
Currently ranked 10th in the ATP rankings, Isner is perhaps best known for his 11-hour marathon match against Nicolas Mahut at Wimbledon in 2010.
However, this year he has taken his game to a new level with wins over world number one Novak Djokovic and Roger Federer helping him into the top 10 for the first time in his career and become the top-ranked US player.
Isner, whose big-serving game is well suited to the grasscourts, joins Juan Martin Del Potro, Richard Gasquet, Stanislas Wawrinka, Gael Monfils and Alexander Dolgopolov in the field. Two places remain to be filled.
In addition, several other big names are likely to play one-off exhibition matches during the week - as Andy Murray and Djokovic did last year.
