Dineen sees room for improvement
Roscommon U-21 manager Nigel Dineen admitted that his side "slackened off" as Leitrim staged a second-half rally in Kiltoom.
The defending champions led by 13 points at half-time, but failed to build on that despite the wind at their backs.
Two goals from Leitrim substitutes Ciaran Gilheany and Martin Beirne pared the margin back to five points with 13 minutes remaining, but late scores from Ciaran Murtagh and the Smith brothers, Donie and Enda, saw Roscommon home.
"The first half went well, but Leitrim won the second half. I'm obviously disappointed with the way the lads slackened off," said Dineen. "The effort wasn't good enough to win a championship game. The lads switched off and we just couldn't get them to lift their performance."
Roscommon ran riot in the opening half, scoring four goals. Colin Compton raised a green flag inside 15 seconds. Man of the match Cian Connolly found the net in the 19th minute, before Compton struck again 30 seconds later.
When Donie Smith netted Roscommon's fourth goal in the 23rd minute, there was no way back for Leitrim despite their best efforts.
