Defending champion Ronnie O'Sullivan reached his fifth World Championship final with a comfortable 17-11 victory over Judd Trump at the Crucible.

O'Sullivan led 14-10 after the first two sessions, although Trump played his part in some gripping exchanges.

But Trump's mistakes caught up with him on Saturday, with O'Sullivan winning three of the four frames played.

O'Sullivan will play either Ricky Walden or Barry Hawkins in the final
