Using the pure spinor formalism, a gauged linear sigma model is constructed for the superstring on AdS_5xS^5. In the zero radius limit, the Coulomb branch of this sigma model is interpreted as D-brane holes which are related to gauge invariant N=4 d=4 super-Yang-Mills operators. As in the Gopakumar-Vafa-Ooguri derivation of open-closed duality for Chern-Simons theory, this construction may lead to a worldsheet derivation of the Maldacena conjecture.
