Ronnie O'Sullivan cruised into the Northern Ireland Open quarter-finals with a 4-1 win over Zhou Yuelong.

A break of 132 helped O'Sullivan advance to a last-eight match against David Gilbert, who whitewashed Lu Ning.

World number one Mark Selby progressed 4-2 against Martin O'Donnell and will play Thepchaiya Un-Nooh of Thailand.

Judd Trump, Peter Ebdon and Ryan Day are also through but Ali Carter lost a final-frame decider against Eden Sharav at the Waterfront Hall.

O'Sullivan has dropped just two frames in his four matches this week and he recovered well from losing the opening frame of his fourth-round contest to seal a comfortable victory.

Three-time world champion Selby remains on course for a semi-final against O'Sullivan after recording five breaks of 57 or more during his match against O'Donnell while world number five Trump won three frames in succession to defeat Belgium's Luca Brecel 4-2 and set up a quarter-final against Day, who beat Andrew Higginson without losing a frame.

Sharav recovered from 3-1 behind to upset Carter 4-3 and the Israeli will next play Ebdon after the 2002 world champion beat Li Hang 4-1.
