We investigate whether the Affleck-Dine mechanism can produce a sufficient baryon number in the universe in gauge-mediated supersymmetry breaking models, while evading the cosmological moduli problem by latetime entropy production. We find that g-ball formation renders the scenario very unlikely to work, irrespective of the detailed mechanism of entropy production.
