The opening day of the new season was also memorable for a 147 break compiled by Ryan Day.
Judd Trump advanced to the second stage of the Championship League after topping Group 1 in Milton Keynes on Sunday.
The world number one launched his 2020/21 campaign with victories over Fan Zhengyi and David Lilley, before a 2-2 tie with veteran Alan McManus.
That left three-time Championship League winner Trump with seven points and a comfortable passage through to the next group stage in October.
The Englishman is looking to bounce back from failing to defend his World Championship title last month, having triumphed in a record six ranking event tournaments throughout the 2019/20 term.
Meanwhile, there was immediate excitement on day one at the Marshall Arena as Ryan Day compiled his second career maximum break.
The Welshman made the perfect contribution in the final frame of his 3-1 defeat of Rod Lawler, and he later added a 3-0 success against Paul Davison to pip countryman Matthew Stevens at the top of the leaderboard.
The 40 year-old, a runner-up in this competition under its previous guise in 2017, will also move forward to the next phase.
UNBELIEVABLE!

Trump and Day will have to wait a while to rejoin the competition with plenty of action to be played over the next few weeks.
Previously always an invitational event, the third edition of the Championship League in 2020 has been opened up to every professional player and will for the first time carry ranking points.
A total of 128 players will cue up in a unique format which incorporates a round-robin as well as short encounters that will last only four frames.
Because of the vastly increased field, this edition is set to take place over three separate weeks on the snooker calendar.
The first two weeks are effectively qualifiers for the third and final stint of action in late October that will ultimately provide the champion.
There are 32 groups at the outset comprising four players in each, with the 32 winners following the mini-league phase advancing to the second stage.
The first 16 groups will be contested this week, while the remaining 16 groups from phase one will undertake their fixtures at the end of September and into October.
