This paper deals with the natural lift curves and the geodesic sprays for the spherical indicatrices of the timelike-spacelike Bertrand couple on the tangent bundle T(S-1(2)) or T(H-0(2)) in Minkowski 3-space and then give some new characterizations for these curves. Additionally we illustrate an example of our main results.
