We report final measurements of direct CP-violating asymmetries in charmless decays of neutral bottom hadrons to pairs of charged hadrons with the upgraded Collider Detector at the Fermilab Tevatron. Using the complete root s = 1.96 TeV proton-antiproton collisions data set, corresponding to 9.3 fb(-1) of integrated luminosity, we measure A(A(b)(0) -> p pi(-)) = +0.06 +/- 0.07(stat) +/- 0.03(syst) and A(A(b)(0) -> pK(-)) = -0.10 +/- 0.08(stat) +/- 0.04(syst), compatible with no asymmetry. In addition we measure the CP-violating asymmetries in B-s(0) -> K-pi(-) and B-0 -> K+pi(-) decays to be A(B-s(0) -> K-pi(-)) = +0.22 +/- 0.07(stat) +/- 0.02(syst) and A(B-0 -> K+pi(-)) = -0.083 +/- 0.013(stat) +/- 0.004(syst), respectively, which are significantly different from zero and consistent with current world averages.
