Mark Allen missed out on a place in the World Snooker Championship quarter-finals despite compiling the 15th Crucible 147 as qualifier Chris Wakelin powered his way to victory.
In an extraordinary second session, Allen fired his maximum in the 13th frame – in the process becoming the first player to do so in all three Triple Crown events – having failed to pot a single ball in any of the previous three as Wakelin turned a 6-2 overnight lead into an almost irretrievable 10-2 advantage by the mid-session interval.
