In this letter, we propose an explanation to account for the source of the Sunyaev-Zeldovich decrement measurement reported by Jones et. al (1997) in the direction of the distant quasar pair PC1643+4631 A \& B. Invoking energetic quasar winds, we argue that this decrement is the {\bf{kinematic}} signature of the baryons that have been concentrated by the mechanical outflow from the two quasars which are at similar redshift. The magnitude of the effect scales with the luminosity of the QSO outflow, and is larger than predicted for a single QSO in this case as the line of sight fortuitously intersects two QSO outflows with same sign radial velocity. We estimate that the number of similar amplitude decrements expected from the outflows of radio-quiet QSOs to be rare, in roughly 1 -- 3\% of all high-redshift QSOs.
