The transverse spin correlations A_{x,x} and A_{y,y} have been measured inthe pol{d} pol{p} -> p_spec {pp}_s pi- reaction at COSY-ANKE at 353 MeV pernucleon. Here {pp}_s denotes a proton-proton pair with low excitation energy,which is dominantly in the 1S0 state. By measuring three protons in the finalstate it was possible to extract events where there was a spectator protonp_spec so that the reaction could be interpreted in terms of quasi-free pol{n}pol{p} -> {pp}_s pi-. The proton analyzing power in this reaction was alsodeduced from this data set by averaging over the polarization of the deuteronbeam. The values of A_y^p were shown to be consistent with a refined analysisof our earlier results obtained with a polarized proton incident on a deuteriumtarget. Taking these data in combination with our earlier measurements of thedifferential cross sections and analyzing powers in the pol{p} p -> {pp}_s pi^0reaction, a more robust partial wave decomposition was achieved. Threedifferent acceptable solutions were found and the only way of resolving thisambiguity without further theoretical input would be through a measurement ofthe mixed spin-correlation parameter A_{x,z}.
