by Judd Trump winced a slow start to create a lead of 5: 3 against Shaun Murphy until the end of the first meeting of her second round of the World Cup on the Crucible.
Trump had initially threatened his former colleague before recovering to claim the initiative before resuming her best-of-25 frames match-ups on Sunday evening.
Murphy opened with a break of 75 and doubled his advantage before Trump stirred and made sure that the match was the interval of the middle of the session.
A break of 103 in the next frame swung the swing to Murphys, but Trump switched on the style to take the next three one after the other.
Trump wanted to publish his 99th century of the season in the last framework of the session just to miss a difficult yellow on the side pillow when his break was 98.
Trump has compiled 98-century breaks so far this season and will have a bonus of £ 100,000 if he reaches the 100-mark bonus before the end of the tournament.
Zhao Xintong booked his place in the quarter-finals for the first time after achieving a 13:10 victory against his Chinese compatriot Lei Peifan.
Zhao held a late increase in his opponent, the conqueror of the first round of defending champion Kyren Wilson, who won three consecutive frames after Zhao had moved 12: 7 within one victory.
The former British champion, which had recently returned after serving a two-game ban on participation in a betting scandal, will compete against qualification man Chris Wakelin in the past eight years.
