At age 3 Sampras discovered a tennis racket in the basement of his home and spent hours hitting balls against the wall. In 1978, the Sampras family moved to 
Palos Verdes, California, and the warmer climate there allowed seven-year-old Pete to play more tennis. From early on, his great idol was Rod Laver, and at 11 Sampras met and played with him. The Sampras family joined the Jack Kramer Club, and it was here that Sampras's talent became apparent.
