De Sousa the new second favourite with BoyleSports for Leicester success

Jose de Sousa (Lawrence Lustig, PDC)

Jose de Sousa is now the biggest threat to Gerwyn Price according to a shake-up in the betting after the first round of the BoyleSports World Grand Prix.

There were a series of shocks in the bottom half of the draw on Monday, but De Sousa made no mistake with a 2-0 victory over Glen Durrant.

The Portuguese was slashed into 13/2 second favourite from 12/1 with BoyleSports to land his second televised title this weekend.

World number one Price, however, saw his odds shorten further without even throwing a dart on Monday night as former World Champions Gary Anderson, Peter Wright and Michael van Gerwen all found themselves on the wrong end of first round upsets.

The defending champion has been backed down to 2/1 from 5/2 ahead of his second round assignment against Mervyn King, while compatriot Jonny Clayton is the new third favourite having fallen into 15/2 from 18/1 following his victory over Callan Rydz.

Lawrence Lyons, spokesperson for BoyleSports said: "Gerwyn Price continues to shorten by the day, but we've had to cut Jose de Sousa into 13/2 from 12/1 in the other half of the draw.

"He was a hot favourite for his first round match but he has still enjoyed a significant spike in support, so plenty clearly believe his path to the final is a little clearer."
