John Higgins and Joe Perry each won their groups on Thursday to complete the line-up for stage three of the Championship League in Milton Keynes.
Four-time world champion Higgins, winner of this competition in 2017 and 2018, topped Group G after defeating Tom Ford 3-0 in his final match of the day.
The Scot had earlier won 3-0 against Jamie Clarke, then lost 3-0 to Martin Gould, who subsequently finished behind Higgins after his encounter with Clarke ended in his second 2-2 draw of the day.
Perry, who won the inaugural Championship League in 2008, beat Tian Pengfei 3-1 and Li Hang 3-0 before drawing with Mark Davis as he claimed first place in Group H.
Higgins and Perry join Ken Doherty and Kyren Wilson in Group 2 of the third stage, while Judd Trump, Mark Selby, Zhou Yuelong and Zhao Xintong are in Group 1.
The matches in those groups and the subsequent final all take place on Friday.
