A search for the exotic meson X(5568) decaying into the B-s(0)pi(+/-) final state is performed using data corresponding to 9.6 fb(-1) from pp collisions at root s = 1960 GeV recorded by the Collider Detector at Fermilab. No evidence for this state is found and an upper limit of 6.7% at the 95% confidence level is set on the fraction of B-s(0) produced through the X(5568) -> B-s(0)pi(+/-) process.
