Davis out, O'Sullivan eliminated

SHEFFIELD, England - Australian Neil Robertson fired in a break of 107 to wrap up a 13-5 win over six-time former champion Steve Davis on Wednesday to reach the world championship semifinals.

Robertson, who had led 12-4 overnight, was briefly delayed after Davis took the opening frame of the afternoon with a break of 59, but he took his first real chance to clinch his place in the last four, where he will meet Ali Carter who beat Shaun Murphy 13-12.

Davis had caused the shock of this tournament by knocking out last year's winner, John Higgins, in the second round, 21 years after his last Crucible triumph.
