Top-ranked Pete Sampras played through a sore shoulder and beat Thomas Muster 6-1, 4-6, 6-2 in a Paris Open quarterfinal Friday and went to the clinic for precautionary X-rays.
Sampras was sharp at the start, rolling to a 5-0 lead in 16 minutes and wrapping up the first set at 6-1 behind stinging backhands and five aces.
After rolling to the first set in 20 minutes and looking like he had the match well in hand, Sampras called to the trainer after the fifth game of the second set to have his upper right arm and shoulder treated.

Sampras was scheduled to play Yevgeny Kafelnikov today. Jonas Bjorkman and defending champion Thomas Enqvist play in the other semifinal.
