World number three Neil Robertson was on the wrong end of the shock of the Gibraltar Open so far, losing to 17-year-old Lei Peifan from China.

The Australian, the current UK champion, looked out of sorts as he slipped to a 4-2 first-round defeat.

Lei got on the road to the biggest win of his short career thanks to an 80 clearance in the third frame.

He missed a presentable blue which would have all but secured a 4-1 win, but gathered himself with a 56 break to get over the line.

Former champion Stuart Bingham beat Gerard Greene 4-0 to set up a meeting with Jimmy White.

Alan McManus was also a 4-0 winner against Kacper Filipiak, Rod Lawlor edged out Welsh Open winner Jordan Brown 4-3 and there were also wins for Anthony Hamilton, Anthony McGill and Ali Carter.

Ryan Day, the winner in 2018, lost 4-3 to fellow Welshman Jak Jones.
