The Miniplug calorimeters, designed to measure the energy and lateral position of particles in the forward pseudorapidity region of 3.6 < |eta| < 5.1, have been installed as part of the CDF upgraded detector for Run II at the Tevatron. Proton-antiproton beams are colliding at sqrt s = 1.96 TeV. One year after installation, Miniplug detector performance and first results are presented.
