The single-spin asymmetry A(p̄p) for inclusive π production at 0.5<p<2 GeV/c by 200 GeV transversely-polarized anti-protons on protons has been measured at Fermilab over a wide range of x. We observe that A(p̄p) has the same sign, a similar x dependence, and about half the magnitude as A(pp) for π production by protons. We also present the ratio of the spin-averaged cross sections for π production by antiprotons and by protons.
