After an early exchange of kicks in the final, Tigers duo Crane and Smith combined to create an opportunity for Bath wing Matt Banahan to score the opening try, his sixth of the tournament, and give England a 13-6 lead.
That advantage was cut to four points before half-time but Crane completed a 50-metre run-in to the line with five minutes remaining to stretch the England lead to 31-19 before Ugo Monye added a final touchdown.
Crane also collected the Barclays Man of the Series award at the final whistle.
