The win continues Selby’s excellent form, having regained the world number one last month after winning the UK Championship.
'The Jester from Leicester' broke ahead from the start and before long was leading 2-1, but the match soon turned into a war of attrition as Dott made a phenomenal break of 106 to claim the fourth frame.
An epic 38-minute fifth saw the Scott Dott up 3-2, and seemingly on his way to his first professional title since the 2007 China Open.
Selby wasn’t ready to accept defeat, however, and drew on two excellent breaks of 72 and 90 in the penultimate and deciding frames to secure victory.
