Concede 7 balls ... absolutely ridiculous! A petulant child's reaction to a bad roll!
Did you watch the stream? There was no "bad roll', he missed the match 8 ball after getting just a little funny on his second to the last ball before the 8. He tried a risky position play and left himself a makeable but tough 8 for the match. I would say Thorpe's chance of getting out with the 3 balls he had left was about 95-99%, probably the same of Joey running out his open table after the miss. I understand the frustration but not smart to concede, IMO He messed up, Joey could've too.
