World number two Neil Robertson has been knocked out in the first round of the World Championship by England's Robert Milkins.
Milkins, ranked 19th in the world, defeated the 2010 champion 9-8 at the Crucible in Sheffield on Thursday.
"Today was a bit scrappy; I think I got him twitching a bit and I was twitching as well," the 37-year-old told BBC Sport.
Milkins's reward for beating Robertson is a second-round tie against fellow countryman Ricky Walden.
