  We investigate the b-u skewed parton distributions (SPDs) for B->pi
transitions and determine the contributions from several sources (overlaps of
soft light-cone wave functions, quark-antiquark annihilations and meson
resonances). The B->pi transition form factors, which are relevant in exclusive
semi-leptonic and non-leptonic B-decays, are obtained by integrating the b-u
SPDs over the momentum fraction x. A phenomenological determination of the
relevant parameters allows us to predict the form factors and to obtain the
branching ratios for semi-leptonic B->pi decays.
