Recent measurements of the mass of the top quark (t) are
presented using 162 pb-1 of data of p anti-p collisions at s**(1/2) = 1.96 TeV
collected by the CDF detector at the Tevatron collider during Run II. The
analyses focus on the semi-leptonic decay mode t anti-t --> (bl nu)(b-bar
qq-bar) with one or two identified bottom quarks (b). The Template Method
(TM) reconstructs the invariant mass of the top quark in each event. The
Multivariate Template Method (MTM) enhances this approach by adding
information on the event topology. The Dynamical Likelihood Method (DLM)
discriminates between possible mass values using top quark decay observables
and attempts to use the maximum amount of information on top quarks provided
by the Standard Model. All three models produce similar results. The
Dynamical Likelihood Method yields a top quark mass of 177.8+4.5_-5.0(stat)
+/- 6.2(sys) GeV/c2.
