Smackdown vs. raw 2006 question?

how do you beat the undertaker in the buried alive match? he keeps reopening the casket i pushed him in like 8 times and i'm getting bored of beating him senseless and bringing his dreams of being a great writer to an end by slamming his fingers in a casket multiple times and turning them into sausages.... lol but really is there anyway to prevent him from reopening the casket?
