TENNIS ROUNDUP : Sampras Strains Hamstring, Retires in the Second Set

Pete Sampras strained his left hamstring and retired in the second set of a third-round match against Mark Koevermans in the Volvo indoor tennis tournament Thursday night at Memphis, Tenn.

Sampras, ranked No. 5 in the world and seeded second in this tournament, led, 6-2, 1-1.

Sampras was hurt early in the first set, said Bob Russo, Assn. of Tennis Professionals trainer. Sampras had the leg taped but was unable to continue for fear of making the injury worse, Russo said.
