Mandigers saw off the vastly experienced Paul Hogan with some clinical finishing throughout the contest.
This included two ton plus checkouts and was just below 50% on the doubles to underline this.
Ferenc was impressive in his win over Ryan Hogarth and could pose a serious threat to Scott Mitchell in the next round.
He won two of the sets with a clean sweep against an opponent who was highly fancied beforehand to see off the Serbian.
