First evidence for single top quark production has recently been found by both the D0 and CDF experiments. By combining three analyses, D0 measured a cross section of s(p[`p] tb+X, tqb+X ) = 4.7 1.3  pb, with a significance of 3.6 standard deviations, and CDF's matrix elements analysis measured a cross section of s(p[`p] tb+X, tqb+X) = 3.0 +1.2-1.1 pb, with a significance of 3.1 standard deviations. These analyses also provided the first direct measurements of the CKM matrix element, |Vtb|, without assuming unitarity. This paper briefly describes the latest single top production results from the two experiments.
