of the USA will be looking to have a superb run on Clay this year at the French Open in Paris.
The American has reached the 4th round at the last 2 Grand Slams that he competed in the US Open last summer and the Australian Open this year.
At the US Open last year Isner stunned the former world number 1 and his compatriot Andy Roddick in 5 sets and reached the 4th round where he lost to Fernando Verdasco in 5 sets.
This year Isner maintained his good record against Gael Monflis beating the Frenchman in 4 set at the Australian Open before losing to the eventual finalist Andy Murray in straight sets.
The American recently reached the final of the ATP Event in Serbia on Clay but lost to good friend and fellow American Sam Querrey.
Isner and Querrey also teamed up in the Davis Cup in Serbia earlier in the year.
