  The weak decay of a polarized top quark has a rich structure of angular
correlations among its decay products. We describe some of the noteworthy
features of such decays. We then examine the three modes of single top
production, with an emphasis on the status of calculations of the degree and
direction of polarization at Run II of the Tevatron. The associated production
of a top quark with a W boson will be very difficult to observe at the
Tevatron. Prospects for observing the other two production mechanisms are much
better. The spin state of the produced top quark is understood at leading order
in the W* production channel. For the Wg-fusion process, we present new results
including the resummed logarithmic corrections of the form ln(mt^2/mb^2). The
spin-dependence of the complete order alpha_s corrections to either of these
processes has not yet been determined. The fraction of spin up top quarks is
large (approx. 95%) for both modes provided that the appropriate spin
quantization axis is chosen.
