A brace to Valentine Holmes helped the Maroons to a six-point win on Wednesday night.

That result means the series finishes 2-1.

Cordner was left feeling slightly hollow after the Blues fell short at Suncorp Stadium.

"Obviously it's pleasing to get the series win but it's a bit empty you know, like losing tonight," he told Channel 9.

"You can't help... but it takes the edge off it a bit. In saying that I'm just really proud of what we achieved as a team this series. We worked really hard, we came together.

"All of our hard effort got us the series win. But it puts a bit of a dampener on it losing tonight."
