The CDF and D0 collaborations at the Tevatron have produced
exquisite precision measurements on high-p(t) physics with their large
datasets of p anti-p collisions.  The top quark is being studied in great
detail, and a precision of 1.1% in the measurement of its mass has been
achieved.  The large datasets of W and Z boson decays have allowed the
most precise measurement of the W mass to date, and detailed studies
of production and decay asymmetries; moreover, associated production
of pairs of vector bosons have been observed and measured.  The precise
knowledge of top and W masses are providing decisive new input for the
allowed mass range of a standard model Higgs boson, as well as for the
parameter space of benchmark scenarios in supersymmetric theories.
