Roscommon will play in the Christy Ring Cup in 2016 following their 2-14 to 0-13 victory over Mayo on at Pearse Stadium on Sunday.
A brace of second-half goals from John Coyne earned Roscommon their place in the Christy Ring Cup.
Coyne, who featured as a half-time substitute in their Nicky Rackard Final win over Armagh last weekend, was also introduced at the interval in this Western derby, and made a strong impact.
The sides were level on three occasions during the first-half, including at the interval at 0-07 apiece.
Jerry Fallon (0-03) and Micheal Kelly (0-02) kept the scores ticking over for Roscommon while Kenny Feeney (0-07) and Fergal Boland (0-03) were on target for Mayo.
But, Roscommon were goal hungry and although Kelly was denied from the penalty spot in the opening half, they carved open the Mayo defence in the closing 35 minutes.
A John Coyne goal kick-started a dominant spell from Roscommon on the restart, who stayed ahead until the end despite strong Mayo pressure.
It was a second piece of silverware for Roscommon and their captain Micheal Kelly inside eight days, with the game also doubling up as the Connacht Intermediate Championship Final.
