He broke in particular at 4-3 which changed the game hitting a 91 checkout for a 12-darter and followed it up with a clean 80 checkout to hold before breaking again for the win.
This was in the form of an 87 checkout on double 18 for an 11-darter as rampant Ratajski sealed a superb conclusion to the tie.
As did Ross 'The Boss' Montgomery who marked his European Tour debut with a win against fellow veteran, Marko Kantele.
It was a hard fought win for the Scot against the Finn, but he sealed it in style smashing in a superb 161 checkout to hold through at 5-4 and stop it going all the way to a decider.
In terms of the second round, Ratajski will face Dimitri van den Bergh. While for 'The Boss', it is going to be Jonny Clayton.
