We present measurements of the forward-backward charge asymmetry in top pair production using 1: 9 fb(-1) of p (p) over bar collisions at root s = 1.96 TeV recorded with the Collider Detector at Fermilab II. Correcting for acceptance and measurement dilutions we obtain parton-level asymmetries of A(FB)(p (p) over bar) = 0.17 +/- 0.08 in the p (p) over bar frame and A(FB)(t (t) over bar) = 0.24 +/- 0.14 in the t (t) over bar frame. The values are consistent with the standard model expectation and disfavor exotic production mechanisms with significant negative values.
