  We present a binary channel for the progenitors of long gamma-ray bursts. We
test the idea of producing rapidly rotating Wolf-Rayet stars in massive close
binaries through mass accretion and consecutive quasi-chemically homogeneous
evolution. The binary channel presented here may provide a means for massive
stars to obtain the required high rotation rates. Moreover, it suggests that a
possibly large fraction of long gamma-ray bursts occurs in runaway stars. This
can have important observational consequences for both the positions of GRBs,
and their afterglow properties.
