Tomas Berdych and Tommy Haas are the latest players to be confirmed for the Aspall Tennis Classic ahead of Wimbledon.
Two more added to Aspall line-up
The duo have been added to the bill for the Wimbledon warm-up tournament, which is staged at the Hurlingham Club in Fulham between June 27-30.
World number 14 Berdych will use the tournament to prepare for the Grand Slam event as he looks to go one better than his 2010 runner-up performance at SW19.
Experienced German player Haas, 39, will also appear as he attempts to enjoy another Wimbledon, where his best showing was a semi-final appearance in 2009.
Previous players confirmed to take part in the Aspall Tennis Classic this year include world number six Milos Raonic, world number 11 Jo-Wilfried Tsonga, David Ferrer, who is ranked at 38, Jack Sock (15) and Lucas Pouille (17).
