Selby out but Lisowski advances in NI Open defence

Reigning champion Jack Lisowski kicked off his defence of the Northern Ireland Open with a 4-1 win against Huang Jiahao in Belfast. Lisowski, 35, had won his first ranking title at the tournament the previous year and quickly took a three-frame lead over his Chinese opponent. Despite Jiahao narrowing the gap to 3-1, Lisowski secured the fifth frame to advance to the next round. He will face Scotland's Anthony McGill, who had also won 4-1 against Stephen Maguire, in round two.

Surprises unfolded on the opening day of the tournament as both Mark Selby and Xiao Guodong were eliminated in round one. Four-time world champion Selby, attempting to become the first player to win the quartet of Home Nations tournaments, was defeated 4-2 by Louis Heathcote. World number five Selby had led 2-0 but dropped four consecutive frames to be defeated.

Xiao Guodong was also beaten in the first round, losing a final-frame decider to England's Sam Craigie. Cork's Aaron Hill also suffered a 4-2 defeat in the first round, this time to Thailand's Thepchaiya Un-Nooh. Former world champions Neil Robertson and Shaun Murphy are among the players in action during the tournament's evening session, which began at 19:00 BST.
