Cross bounced back from his first round exit in Bahrain a week earlier in style to claim the Toon Greebe Trophy, producing a string of top-class displays at De Maaspoort.
Cross followed Friday's defeat of Richard Veenstra with victory over a second Dutchman - Jermaine Wattimena - in Saturday's quarter-finals, hitting six doubles from eight attempts.
The 2018 World Champion then averaged over 100 and finished 50% of his darts at double in his semi-final success against Gerwyn Price.
He then denied Stephen Bunting back-to-back World Series titles by seeing off the Bahrain Darts Masters winner with an 8-5 success in the final, averaging almost 102 and finishing 8/15 doubles.
Cross started the final stronger, leading 2-0 and adding 13-darters to move 3-1 and 5-2 up, only for legs of 14, 12 and 12 darts helping Bunting to draw level - as he took out 62, 94 and 130.
Cross, though, hit back strongly to regain the lead on double 18, before a brace of double eight checkouts sealed glory and a first World Series title in Europe.
