Defending champion Neil Robertson has been knocked out in the first round of the World Grand Prix in Hong Kong following a 5-1 defeat by Jak Jones.
World number three Robertson entered the tournament in good form after reaching the semi-finals of the German Masters last week, but failed to carry his momentum into the tie with Jones.
Robertson started well with a break of 46, but a missed red handed the initiative to Jones, who went on to open up a 2-0 lead.
A break of 88 saw Robertson briefly fight back to win the third frame, but Jones took control afterwards, triumphing in the next three to ease into the second round.
The match in Hong Kong took place only three-and-a-half days after Robertson’s 6-1 defeat by Shaun Murphy in Berlin, with the Australian cutting a frustrated figure throughout.
Former World Championship finalist Jones will play Zhou Yuelong in the second round on Thursday.
Seven-time world champion Ronnie O’Sullivan joined Jones in the second round after recovering from a slow start to beat Joe O’Connor 5-3.
After fighting back from 2-0 down, O’Sullivan levelled the match before losing the fifth frame to slip behind again.
But two breaks of 72 saw O’Sullivan take a 4-3 lead, before wrapping up the match with a fine cut of the pink.
O’Sullivan will play Xiao Guodong in the second round on Thursday as he continues his bid for a record-extending 42nd title.
