Mark Allen's Crucible Comeback

Mark Allen credited 'bad food and a few drinks' for fueling his resurgence at the Crucible after a difficult opening session.

The Northern Irishman found his potting rhythm in the second session, winning seven of the final eight frames to overwhelm Zhang.

Allen's victory keeps his hopes of a first world title alive and demonstrates the mental resilience that has characterized his season.

He will now face either Ross Smith or Robert Milkins in the next round as the tournament continues in Sheffield.
