We present a measurement of the tt production cross section using events with one charged lepton and jets from pp collisions at a center-of-mass energy of 1.96 TeV. In these events, heavy flavor quarks from top quark decay are identified with a secondary vertex tagging algorithm. From 162 pb{sup -1} of data collected by the Collider Detector at Fermilab, a total of 48 candidate events are selected, where 13.5{+-}1.8 events are expected from background contributions. We measure a tt production cross section of 5.6{sub -1.1}{sup +1.2}(stat.){sub -0.6}{sup +0.9}(syst.) pb.
