Phil Taylor booked his place in the World Grand Prix semi-finals with a convincing win against Mark Webster.
'The Power' was rarely troubled as he coasted to a 4-0 victory over the Welshman, who knocked Taylor out of last year's competition.
Meanwhile, defending champion James Wade made it through to the last four with a tricky 4-2 win over Andy Smith.
Northern Ireland's Brendan Dolan also earned a spot in his first major semi-final with a 4-1 victory over Scotland's John Henderson.
