Surfer solos.
first he rips Sentry's head off with his board, while keeping Hulk at bay with a few blasts and a force field...
then he siphon's Hulk and feeds back the energy in the way of a forcefield, whilst also levitating him into the air, keeping him from being able to launch any kind of attack.
eventually either Hulk gets bored or (and I don't believe this is possible but, what the hell) he gets drained of gamma.
