Harris finished third on the Challenge Tour Order of Merit and due to Ted Evetts
already confirming his spot through the Development Tour, 'Code Star' will make his return to the Alexandra Palace.
This is alongside Michael Barnard, who of course won the Challenge Tour by a landslide and also claimed his tour card as a result.
Liu on the other hand came through the
PDC China qualifier. He defeated last year’s qualifier Xiaochen Zong 5-2 in the final.
Previously he has represented China at the 2016 and 2017 World Cup and has appeared at the 2016 and 2018 Shanghai Darts Masters so has experience of the big stage.
