Reigning champion Zhao Xintong raced to a 3-0 lead in the World Championship quarter‑final before the session unraveled. A 122 break and a half‑century in the third frame hinted he was building on the form that saw him beat Ding Junhui in round two. The 29‑year‑old, who has spoken openly about the ‘Crucible curse’, soon felt the weight of defending his title.

Shaun Murphy, 2005 champion, answered with a 69 and then seized four successive frames, flipping the score to 5-3 lead. He wrapped the fifth and sixth frames on the black, exploiting Zhao’s errors, and controlled the seventh. A missed pink in the eighth handed Murphy a two‑frame cushion heading into the Tuesday evening session at 19:00 BST. Murphy’s clinical finish reinforced his reputation for resilience in matches.

Across the hall, Barry Hawkins battled Northern Ireland’s Mark Allen, sharing the first six frames in a high‑quality duel. Hawkins compiled a century and three further half‑centuries, then added breaks of 75 and 63 to seal a 5-3 lead. Both matches resume at 19:00 BST on Tuesday, setting up crucial decisive second‑session showdowns.
