Ballinderry have clinched their third Ulster Club football crown by seeing off a determined Glenswilly side 1-13 to 2-6 in Sunday's final at Healy Park.
Glenswilly, the Donegal champions, had a dream start with skipper Michael Murphy scoring a goal in 27 seconds.
But the Derry side hit back and Michael McIver netted a goal as they built up a 1-6 to 1-2 lead at half-time.
Caolan Kelly scored Glenswilly's second goal but Ballinderry finished the stronger to claim the championship.
Ballinderry will now travel to London to face the Finchley-based Kingdom Kerry Gaels in the quarter-finals of the All-Ireland Club Championship on 15 December.
Ballinderry were the favourites to lift the Seamus McFerran Cup trophy they last won in 2001, but they had top recover after conceding a goal in the first minute.
Glenswilly skipper Murphy was faced with a tight angle and could well have been going for a point, but his left foot shot lopped over Shamrocks keeper Michael Conlon and into the far corner of the net.
Murphy then landed a 45 to put the Donegal men four points ahead.
However, Balllinderry started to assert control on the game with three points - a long-range free by Collie Devlin and scores from play by James Conway and Dermot McGuckin.
Murphy then found Caolan Kelly to score Glenswilly's first point for 13 minutes, but that was to be their last score of the half.
Devlin and Conleth Gilligan scored frees for Ballinderry and then McIver got their goal, pouncing after Ryan Bell's effort had been blocked.
Dermot McGuckin tagged on another point to give the Shamrocks a four-point interval advantage.
Glenswilly, in their first provincial final, staged a superb revival at the start of the second half and scored their second goal when half-back Caolan Kelly fisted in.
With points from Colin Kelly and captain Murphy, the Donegal men had quickly wiped out the half-time deficit and the game was in the balance.
Glenswilly led briefly when Darren McGinley pointed from play but, once again, Ballinderry regrouped and scored six of the final's last seven points to reclaim the title.
Veteran Conleth Gilligan scored two of them, Devlin landed a fine, accurate kick, substitute Aaron Devlin popped one over from close-range and Darren Conway was also on target.
