Game at a glance
Man of the match
Daniel Goulding (Cork)
A return of seven points was priceless for Cork in such a tightly contested match.
Donnacha O'Connor's two scores in the 79th and 81st minute, which gave Cork a vital two-point lead going into the second period of extra-time.
When will the GAA bring in the video for these big games? Mickey Ned O'Sullivan was fuming about John Galvin being denied a penalty in the fourth minute.
Padraig Hughes dished out 17 yellow cards and one red, but liaised well with his fellow officials to deal with outbreaks of petty off-the-ball stuff.
Conor Counihan (Cork manager):
"The heart is fine. That's better than any stress test. Disappointed we didn't close it out in normal time."
Mickey Ned O'Sullivan (Limerick manager):
"There's no such thing as 'not getting over the line'. We'd get over the line if we were better than Cork. We weren't better than Cork."
Wides: Cork 11 (6); Limerick 11 (4).
Frees: Cork 29 (13); Limerick 33 (15).
