Selby: Nerves got to Robertson
Mark Selby completed a 10-1 demolition of Jimmy Robertson at the World Championship - then confessed nerves had strangled his opponent.
Selby wasted little time in claiming the two frames he needed for victory having resumed 8-1 ahead overnight.
A break of 107 in the ninth frame helped Selby seal his progression against an opponent ranked at a lowly 63 in the world.
Selby made only three breaks above 50 in the match. He faces seven-times' champion Stephen Hendry in the last 16 in a match that starts out on Saturday.
"Unfortunately, for Jimmy the occasion seemed to get the better of him," said Selby.
"He started off brilliantly by winning the first frame, but he faded away and missed a lot of balls.
"It's everybody's dream to play at the Crucible, but he didn't show what he's capable of.
"If he was to show any nerves than I expected it to be at the start, but as it went on he got more nervous, which is a bit strange.
"But you have to be a good player to get to the Crucible and I'm sure he'll be back.
"I'm happy to get into the next round, but I need to up my performance if I'm going to go on and challenge for the title.
"You never feel a part of the tournament until you get the first match out of the way and now with it being the best of 25s I feel in the tournament."
