Eight of the 10 matches on the first weekend of the World Open in Glasgow were won by the higher-ranked player, the exceptions being the defeats of Mark Selby, the Masters champion, and Shaun Murphy, the world No7.

Selby went out 3-2 on the final pink to Barry Hawkins, ranked 21, while Murphy was eliminated 3-0 by Dave Harold, ranked 31.

Neil Robertson repeated his world final defeat of Graeme Dott, winning 3-1, after Dott had remarkably won the third frame after needing three snookers.

Allister Carter, winner of the Shanghai Masters this month, won the fourth frame on the black to secure a 3-1 win over Thepchaiya Un-Nooh, the world amateur champion two years ago and the first player of world‑class potential to emerge from Thailand since James Wattana.

Stephen Maguire prevailed 3-2 on the final black over Stuart Pettman after the world No35 had squandered two gilt-edged chances to clinch the decider.
