Murphy edges out Gould
Judd Trump whitewashed Mark Joyce in round one of the World Open in China on Tuesday.
Trump turned on the style in Haikou to show the returning Ronnie O'Sullivan that he is the man to be stopped for the rest of the season.
Reigning world champion O'Sullivan confirmed earlier on Tuesday that his 10-month sabbatical will be ended by a title defence in Sheffield, with the 37-year-old warning that he was keen to add to his trophy cabinet.
In O'Sullivan's absence the likes of Trump and Mark Selby have jostled for top billing, with Trump currently shading the rankings despite Selby winning the UK Championship and the Masters.
The three men head the betting for the World Championship, but while O'Sullivan was announcing his comeback, Trump was whitewashing Mark Joyce 5-0 in their first-round clash in Haikou.
Victory will have tasted even sweeter for Trump too, for it was Joyce who curtailed his defence of his UK title in York before Christmas.
Graeme Dott, beaten by O'Sullivan in the 2004 world final, also won, getting past Jamie Cope 5-2, while another big-name player, Neil Robertson, got the better of Dominic Dale by the same scoreline.
In the day's early session, Mark Allen progressed with a 5-2 win over Ryan Day, while Shaun Murphy needed all nine frames available to see off Martin Gould and will next face Matthew Stevens, a 5-4 winner over Dave Gilbert.
Zhao Xintong and Ian Burns were victors in the wildcard round.
