Ali Carter went undefeated in Group 17 of the Championship League on Thursday at the Morningside Arena in Leicester.
The Captain beat Robbie McGuigan, a replacement for Kurt Maflin, 3-0 in his opening fixture of the day.
A subsequent whitewash defeat of Louis Heathcote mainted a 100% record heading into his last tie with Wu Yize.
Having earned four points from his initial couple of matches, Wu could have pinched first place with a victory over Carter.
But despite seeing his opponent compile a brace of centuries, the latter won the two frames he needed to secure a point and top spot.
A similar situation unfolded in Group 25, with Pang Junxu edging out Ryan Day in the same manner.
Pang recorded a pair of 3-1 successes in his early games with Reanne Evans and Dylan Emery to lead the way on six points.
Day’s victory over Evans and draw with fellow Welshman Emery meant that he needed to beat Pang in order to advance.
However, the former world number six could only draw with the young Chinese competitor, and it was Pang who progressed.
