CDF has resumed the top quark mass measurement with upgraded detectors and Tevatron complex. High statistics should allow us to determine the top mass with an uncertainty of a few GeV/c2 by the end of Run-II. The current measured value, using an integrated luminosity of ~ 108 pb-1, is 177.5+12.7_-9.4(stat.) +/- 7.1(syst.) GeV/c2 (lepton + jets with one b-jet tagged mode: the current best mode), which is consistent with Run-I measurements.
