Hazel Irvine presents live coverage of the second session of the final on day 16 at the Crucible Theatre in Sheffield. After struggling in the opening session, Mark Williams produced an improved display in the evening 12 months ago, but still trailed Zhao Xintong 11-6, and no player had ever recovered from an overnight deficit of five or more frames in a world final at this venue. With commentary and analysis from Steve Davis, Ken Doherty, Steven Hallworth, Stephen Hendry, John Parrott, Joe Perry, Dennis Taylor and Lee Walker
