Ronnie O'Sullivan saved the best for last as he taught Chinese teenager Wu Yize a lesson to make the last 16 at the European Masters. O'Sullivan, who wrapped up a 5-1 victory with a century break, never got out of second gear at the Marshall Arena as the 18-year-old squandered a series of chances to put him under pressure. Wu ran out of position having given himself opportunities to square the match at 2-2 going into the mid-session interval and then to reduce the deficit to 3-2 immediately afterwards, and O'Sullivan punished him on both occasions. However, it was not until the final frame that the Rocket found his usual fluency with a clearance of 112 to clinch victory. O'Sullivan will face fellow Englishman Ashley Hugill in the next round after he recovered from losing the opening frame to take the next five on the trot to beat Ali Carter 5-1.
