We report the first spectroscopy of optical lattice-confined Yb atoms. We demonstrate 20 Hz linewidths using the highly forbidden clock transition (<sup>1</sup>S<sub>0</sub>-<sup>3</sup>P<sub>0</sub>) in metrologically superior even-isotope <sup>174</sup>Yb atoms in a one-dimensional optical lattice.
