Neil Robertson beats Si Jiahui 6-2 in China Open quarter-final: world number one route opens up

A 6-2 win over Si Jiahui in the China Open 2026 quarter-final has sent Neil Robertson into the last four, but more importantly it reopened the race for the world number one spot. The Australian needs two things in China: the title and ranking points. After breaks of 89, 102 and 79, both targets are within reach. The match with Si Jiahui was expected to be a tight contest between a former world champion and a rising young talent. In reality, Robertson controlled most of the play. The 102 break in the deciding frame was a well-timed century; it showed his ability to close out the match with a polished clearance. Fans may regret the chances Si Jiahui missed, but Robertson's full exploitation of every error was what created the difference. Technically, Robertson's three big breaks put his break-building among the highest quality at the moment. Instead of playing on pure instinct, he often kept the cue ball in safe zones and rotated around the 7-6-5 scoring balls. When Si Jiahui tried to turn the match into a safety battle, Robertson accepted controlled risks to find finishing opportunities. This is confidence-based play, not recklessness. For the Australian, a well-timed century is like an opening break shot in billiards: it changes the entire psychological dynamic for the opponent. The China Open is a ranking event on the World Snooker Tour. Therefore, the quarter-final result goes beyond simply advancing; it directly affects the world rankings. Robertson could return to number one if he continues deep into the tournament. Before the event, he said he had won some big titles in the last two years and was 'in the hunt' for top spot. He also stressed that maintaining consistency over several months matters more than any single spectacular shot. But if people used only words to measure Robertson, they would miss the crucial technical signals from his breaks of 89, 102 and 79. The other side of the draw also creates considerable pressure. Mark Selby just made a 138 break and beat Kyren Wilson 6-1 to reach the quarter-finals. If Selby maintains this form, he will be Robertson's toughest opponent in the next round. However, Robertson rarely seems intimidated by defensive players. Experience tells him that an opponent's 138 break only matters in the frame it appears; a match lasting many hours is decided by who handles the break-offs better and who controls the tempo. Meanwhile, the presence of Si Jiahui and Zhang Anda in the main draw is a positive signal for Chinese billiards. These two players can create quality matches against top players, rather than merely filling out the field. The host nation's billiards scene is shifting from a learning phase to genuine competition. Si Jiahui lost to Robertson, but staying focused against a player who can create distance with century breaks will be a more valuable lesson than any easy win. As for the race for number one, the context is special. Judd Trump is still considered the most consistent player of the recent cycle, but Robertson believes he can overtake Trump this month if he wins the title. That message is not a statement; it is backed by results and quality breaks. However, long-time observers also point out a blind spot: Robertson has sometimes lost consistency because he was busy with exhibition events and a dense schedule. This makes the Selby match a bigger psychological test than a technical one. Robertson also spoke about the depth of his title tally as a separate measure. In his comments, he did not directly compare himself with Trump but said he had won 'some big titles' in the last two years and was still 'in the hunt'. His wording shows someone who understands rankings: the number one spot does not come from one brilliant win, but from accumulating points in major events. Looking at his breaks of 89, 102 and 79, Robertson appears to be playing the version of himself needed to defend a leading position. Mark Selby's subplot cannot be ignored. The 138 break in his 6-1 win over Kyren Wilson shows Selby still has the ability to score big when required. If Robertson reaches the final, he would face either Stuart Bingham or Zhang Anda. Bingham is a former world champion, while Zhang Anda is playing with the freedom of someone with nothing to lose. So Robertson's path is far from easy despite his convincing win. The crucial point fans often miss is the rhythm of the match. Robertson won 6-2, but the scoreline accurately reflected that he was often the first to open the scoring in many frames. When a player can take control of the table from the start, the opponent is forced to play more defensively and is more likely to make errors under pressure. Si Jiahui did respond with bold shots at times, but Robertson had enough experience to neutralise them. That is the difference between a veteran champion and a young talent still needing time. In terms of form, Robertson is showing rare consistency at his age. Frequent international play helps him keep his cue ball feel, while selective scheduling keeps him fresh. At this tournament, the question is whether Robertson can maintain his winning run over three consecutive matches. The dense China Open schedule can create surprises, and older players often struggle most in the third or fourth match of the same week. If Robertson wants to overtake Trump, he needs more than a good final; he needs a perfect week. Si Jiahui's story also deserves a long-term view. Against a former world champion like Robertson, Si Jiahui was pushed around at times but did not completely collapse. That shows potential while exposing the gap in handling difficult balls. The young Chinese player will need to learn how to turn defensive shots into attacking weapons, not just escape trouble. Meanwhile, Zhang Anda will have a chance to face Bingham, an aggressive player. If Zhang Anda beats Bingham, a semi-final against Robertson would be a very different story for Chinese billiards. The match against Mark Selby will provide the first answer. Robertson knows that to overtake Judd Trump and return to world number one, he must do more than score points. He needs to prove that the 6-2 win over Si Jiahui is the result of sustained form, not just one explosive moment. If he keeps this rhythm, Robertson will be more than a finalist; he will be a strong favourite for the title. The world number one race is entering its decisive phase, and the Australian is ready for it.
