Dekker stuns Kellett at Lakeside
Second seed Stuart Kellett suffered a shock defeat as he was beaten 4-1 by Dutchman Jan Dekker in the BDO World Championship second round at Lakeside.
Englishman Kellett had produced a stunning debut performance, losing only one leg in thrashing Darryl Fitton 3-0 in the first round on Sunday.
But he was a shadow of that player and offered no excuses for his defeat.
"I felt good but that was embarrassing, I played terrible and he deserved to win," Kellett told BBC Sport.
Dekker took 57 minutes to beat his opponent from Manchester and book a place in the last eight.
"I am very happy," he said. "I first of all just wanted to play at Lakeside and to win was a surprise. It was not a good match.
"I knew that Stuart was a good player but perhaps he did not play his proper game because he was the number two seed."
In complete contrast to the fast throwers - Martin Phillips and Joey ten Berge - involved in the opening game of the evening, Dekker and Kellett were slower and more deliberate, the Dutchman clinching double 16 to take the first set 3-2.
Kellett trailed twice in the next set and Dekker's second 180 in the fifth leg handed him the initiative, but Kellett pounced to clinch a match-levelling 81 checkout, finished on double 18.
Dekker took the opening leg of the third set, Kellett lining up a 170 finish in the next leg and after hitting two 60s agonised as the third bounced out from the bull.
Dekker took the third leg but then the Dutchman suffered a bounce-out on a set-winning double 20.
Kellett levelled but the Dutchman gained some justice when he completed 68 with double 16 to move ahead for the second time.
All three legs of the next set went against the throwing advantage with the Dutchman turning the tide to his favour for a 2-1 lead, adding the next and the set with his favourite double 16.
Twice Dekker led the fifth set, missing bull for a match-winning 94 finish, Kellett missing double 16, and his opponent then missing a further two doubles for victory. Kellett clinched the leg with double four.
But two 140s steered the Dutchman towards his match-winning double four, Kellett becoming the 10th seed this week to exit the competition.
Earlier Wales' Martin Phillips edged out the number five seed Joey ten Berge in a thrilling seven-set encounter.
Phillips held off a spirited comeback from Berge, who recovered from 3-1 down to level, to beat the Dutchman 4-3 and advance to the last eight of the tournament.
"I am too long in the tooth now to worry about whether I win or not. I just come to enjoy myself and it seems to be working for me," said Phillips.
"I have known Joey a long time and knew he would not give up but I just kept plodding on. I really thought it was going to a tie-breaker."
In the final match of Tuesday's action, Gary Robson sealed a shock 4-1 victory over last year's losing finalist Dave Chisnall.
"Dave didn't play at his best, but I'll take the victory," Robson told BBC Sport.
Robson, who now takes on Phillips in the quarter-finals, was in great form as he raced into a 2-0 lead over his fellow Englishman.
Chisnall then responded to take the third set, but Robson held his nerve to seal a thoroughly deserved victory.
