The bookmaker Stan James has launched an investigation into what it describes as "unusual betting patterns" at the Saga Insurance Masters qualifying tournament.
Today's Racing Post reports that SJ returned winning stakes to some punters who had placed bets on four matches played last Sunday.
SJ say they have no problem with the performances of the players involved or the results of the matches but that they "are looking into about a dozen bets placed in a couple of regions in the UK."
The matches concerned were 1/2 shot Liang Wenbo's 5-2 victory over Joe Delaney, 1/3 Ricky Walden's 5-0 hammering of Alfie Burden, Jamie Burnett (6/5 from 11/8) upsetting Joe Swail 5-2 and 5/6 chance David Gilbert's 5-3 win over Joe Perry.
These kinds of stories come round periodically and tend to be nothing more than nervous bookies reacting to unexpectedly high wagers.
I can't say I found any of the results listed particularly surprising but snooker's problem is that there is no apparatus in place to properly investigate allegations made - I remember one time where betting was suspended on two matches and the WPBSA sent an 'observer' into the arena to watch them both at once!
