Reigning champion Shaun Murphy is out of the 2017 World Grand Prix after suffering a 4-2 defeat at the hands of Ryan Day on Friday, while free-scoring Marco Fu enjoyed a success by the same scoreline over Mark King at the Preston Guild Hall.
Murphy’s title defence came to an end after he was outclassed by Day, who made five breaks of 50 or over on the way to booking his place in the semi-finals of a ranking event for the first time in three years.

However, the three-time ranking event finalist moved to the brink of victory after a run of 51 to the blue in the fourth.
The reigning champion kept his hopes alive after eventually taking a scrappy 46-minute long fifth frame on the colours, but split the reds after missing a black off its spot in the next and Day punished with 79 to seal the deal.
