Masters semi-final momentum swings on black

Graeme Dott misses a black that would have put him 5-1 ahead, in his Masters semi-final defeat by Mark Selby.

The moment proved decisive for the momentum of the match, with defending champion Selby producing a run of three straight frames and going on to win the decider.

Earlier in the evening defending champion Neil Robertson produced a superb display to beat Shaun Murphy 6-2 in the first semi-final.
