Ronnie O’Sullivan began his quest for a record-breaking eighth World Championship title with a dominant opening session against Chinese debutant He Guoqiang.
O’Sullivan, 50, took the first five frames and holds a 7-2 advantage, needing only three frames for victory when the match resumes on Wednesday (14:30 BST).
He pulled out of the Masters in January and has only played in three of six ranking events in 2026, reaching the final of the World Open in China last month.
During that tournament he made a break of 153, the highest ever recorded in professional snooker.
O’Sullivan was playing at the Crucible for a 34th season and instantly took control as breaks of 72, 97 and 113 helped him into a 5-0 lead, with 25-year-old He, the world number 47, already looking defeated.
He did manage to win two frames in a row, but O’Sullivan claimed the last two frames of the session, helped by breaks of 52 and 86.
O’Sullivan will be looking to quickly wrap up the match on Wednesday and a victory would set up a thrilling last-16 tie against four-time world champion John Higgins.
