  Searches for the electroweak production of single top quarks have been
started at the Fermilab Tevatron proton-antiproton collider using Run II data
by both the D0 and CDF collaborations. Using a dataset of approximately
160pb^-1, neither experiment finds evidence for Single Top production and sets
95% C.L. upper limits on the production cross section. The D0 limits are 19pb
on the s-channel production, 25pb on the t-channel production, and 23pb on the
combined s+t-channel production. The CDF limits are 8.5pb on the t-channel
production and 13.7pb on the combined s+t-channel production.
