  $AD_{\mathbb{R}}$ is the Axiom of Determinacy for games on the reals (i.e.,
the player play reals. We show that it implies that all sets of reals are
Theta-universally Baire. As a corollary we obtain a model in which $AD$ holds
and all sets of reals are fully universally Baire. Such a model was first
constructed by Larson, Sargsyan and Wilson. Our result complements it as the
technique is purely descriptive set theoretic.
