The SM Higgs boson has been searched in two channels: (1) qq-bar -> WH -> l nu bb-bar for Higgs masses 110 < M_H < 150 GeV and (2) gg -> H -> WW -> l nu l nu for 140 < M_H < 180 GeV, where l epsilon {e, mu}, using about 200 pb^-1 CDF Run II data. 95% C.L. limits on each Higgs production at TeVatron at sqrt s = 1.96 TeV were set as a function of Higgs mass by fitting the distribution of dijet mass (1) and dilepton azimuthal angular separation (2). We have significantly advanced the sensitivity to the SM Higgs boson cf. Run I.
