Antrim's promotion ambitions were dealt a fatal blow as they fell to a two point defeat to Roscommon at Casement Park.
A late Anto Healy goal put a gloss on the final score for the Saffrons who were second best throughout. It took Frank Dawson's side a full 27 minutes to register their first score from Conall Kelly by which time Roscommon had posted four, two coming from the impressive Colin Compton and the Westerners led 0-7 to 0-1 at the break.
Roscommon picked up where they left off in the second half with Compton pointing before substitute Tomas McCann pointed a 48 minute free for Antrim.
The hosts staged a mini-revival but Roscommon were always able to keep daylight between the teams.
There were no complaints from the Antrim camp after, with manager Dawson saying: "It just wasn't good enough. They simply worked harder than us."
