Anthony McGill 12-13 Si Jiahui
Si Jiahui edged an epic quarter-final against Anthony McGill to reach the semi-final for the first time.
The 20-year-old Chinese debutant put himself 4-1 up only to see McGill claw back to lead 8-6, 10-8 and 11-9.
However McGill has failed to beat Si - ranked 59 places below him - in three previous meetings and this run was extended to four after the Scot lost the deciding frame 13-12.
Si will now face Luca Brecel for a place in the final on Thursday.
