We present a measurement of the mass difference m(Ds+)-m(D+), where both the Ds+ and D+ are reconstructed in the φπ+ decay channel. This measurement uses 11.6 pb-1 of data collected by CDF II using the new displaced-track trigger. The mass difference is found to be m(Ds+)-m(D+)=99.41±0.38(stat)±0.21(syst)MeV/c2.
