I just watched their 1990 USO battle (Sampras in 5 sets). Although Lendl's on court demeanour wasn't that adorable, after the defeat which must have been bitter, he kindly patted on Pete's shoulder. Also, Pete listed his stay at Lendl's and practice with him one of this memorable moments. What's the relationship? Why would Lendl invite this young hotshot to his home? T.
