The Englishmen are the fifth and sixth players to make it through.
Jack Lisowksi lost his last two games but managed to hold onto second place by the skin of his teeth and reach the final group phase of the WST Pro Series on Friday.
The 29 year-old looked to be in complete control of Group 3 after winning the first five of his round-robin encounters in Milton Keynes.
But defeats against Mark Davis and Sam Craigie towards the end of the day’s play meant that he finished on 15 points – the same number as both Craigie and Barry Hawkins.
Craigie stole top spot in the group on frame difference, finishing off with three successive 2-0 triumphs to reach the last eight of a ranking event for only the second time in his career.
Lisowski, meanwhile, edged Hawkins thanks to his 2-1 victory over the Hawk earlier in the day, with the duo otherwise boasting identical records.
By finishing third, however, Hawkins guaranteed his spot in the upcoming Tour Championship at the Celtic Manor.
Lisowski and Craigie join Ali Carter, Mark Williams, Kyren Wilson, and Xiao Guodong in the final group stage of the Pro Series that takes place on Sunday, with two more players hoping to complete the line-up on Saturday.

What is the WST Pro Series?
The format for the WST Pro Series is quite similar to that which was utilised for two out of the three editions of the Championship League that were staged during 2020.
There are 16 groups comprising eight players in each, with a round-robin phase determining the top two who will advance to the second group stage.
Eight groups in the first stage already took place in January, while the outcome from the remaining eight groups will be determined over the coming days.
The 32 players who progress to stage two will be split into four more groups of eight, with the top two again moving forward from each to contest the final group.
That remaining set of eight players will subsequently battle it out in the same fashion to become the overall champion.
There is a total tournament prize fund of £420,500, broken down in various ways throughout the three group stages.
The winner, however, stands to collect at least £30,000 in an event that incorporates a sprint best-of-three frames format throughout.
Live coverage will be available via an account with several online bookmakers, as well as around the world through the Matchroom.Live streaming service.
