Kong KO's defending champ Kist

Defending BDO darts champion Christian Kist has made a shock first round exit at the hands of Robbie Green at Lakeside.

The Dutchman was a shadow of the player that won last year's tournament as a rank outsider against Tony O'Shea.

Kist came into the event unseeded following a disappointing season and proved no match for the fifth seed known as 'Kong', eventually going down by three sets to one.

Earlier, Ireland's Jason Cullen came through by the same scoreline against 11th seed Martin Atkins while Garry Thompson dumped out another seed, Gary Robson, also 3-1.

In the pick of the day's other matches, last year's runner-up O'Shea takes on John Walton while Darryl Fitton faces Benito van de Pas.
