  We use holographic QCD to study Pomeron- and Reggeon-mediated central
production in Regge regime hadronic scattering. We focus specifically on $\eta$
production in proton-proton collisions. While previous work studied the
Pomeron-mediated process, the mesonic Regge trajectories ("Reggeons") we now
incorporate contribute significantly at experimentally probed energies. We use
the five-point open string amplitude (in flat space) to construct approximate
propagators for the Reggeon states, and the five-point closed string amplitude
for the Pomeron. Using these "holographic" Reggeons and Pomerons, and
low-energy couplings derived in the Sakai-Sugimoto model, we compute the
differential and total cross sections at $\sqrt{s}$ =29.1 GeV. Our calculation
of the total cross section is $\sigma =236 \ \mathrm{nb}$, while the
experimentally measured value is $\sigma = 3859 \ \mathrm{nb}$. The discrepancy
between our result and the measured value may indicate that our model
systematically underestimates the values of the relevant coupling constants.
