GOLD Coast's new level of maturity was tested on Sunday, but ultimately prevailed, with a grinding 19-point win over Euro-Yroke at Marvel Stadium.

The Suns looked slick in jumping to a 29-point lead at half-time, but had to withstand a desperate Saints outfit before easing home with a strong final term to win 12.8 (80) to 8.13 (61).

The Suns were just polished enough to keep the Saints at arms length most of the contest.

Gold Coast jumped out of the blocks early before the Saints managed to squeeze back, getting on the scoreboard in the first quarter and stemming the flow.

Although the Saints had the better of the third quarter, they couldn't capitalise where it counted.

Regularly winning the ball back in centre field, the Saints would kick just 1.6 for the term to nibble the lead back to 19 points by the final change.

Nasiah Wanganeen-Milera finished with a career-high 36 disposals and a goal, while Jack Steele (33) had the better of his battle with Matt Rowell. Cal Wilkie was magnificent on King, while Cooper Sharman (three goals) and Mitch Owens (two) were dangerous in attack.

When the Saints had momentum, they were too often wasteful with ball in hand and never had the Suns under genuine scoreboard pressure.
