Top seeds stumble out of Masters

BDO world champion Mark Webster and number one seed Gary Anderson both crashed out of the Winmau World Masters at the last-16 stage.

Wales' Webster lost 3-1 to qualifier Ross Montgomery, while Scot Anderson was beaten 3-1 by Robert Wagner.

Montgomery's joy was short-lived though as he lost his quarter-final to Tony O'Shea, who defeated Ted Hankey.

Scott Waites and 2007 world champion Martin Adams also progressed to complete the semi-final line-up.

With Anderson and number two seed Webster eliminated, England's Adams is the highest ranked player left in the tournament.
