We take the Sakaguchi class of analytic univalent functions 
which are starlike with respect to symmetric points in the 
open unit disc $\Delta$ and extend it to the complex-valued 
harmonic univalent functions in $\Delta$. A necessary and 
sufficient convolution characterization for such harmonic 
functions is determined. Also, a sufficient coefficient 
bound for these functions is introduced which in turn proves 
that they are harmonic starlike of order 
${\alpha}/2,\ {0}\le{\alpha}<1,$ in the open unit disc.
