There were immediate calls for a return fight - this time on home ground for Katie Taylor.
Taylor defeated Puerto Rico's Amanda Serrano Saturday night in what was the first boxing match headlined by two women at New York's Madison Square Garden.
It was a toe to toe battle that ended in a split decision in favor of the Bray, County Wicklow fighter.
Taylor, who won a gold medal in the 2012 Olympics, stays undefeated and improved her career record to 21-0 with six knockouts.
The 35-year-old won the split decision in front of a capacity crowd at the Garden, successfully defending her women's lightweight titles in the WBA, IBF, WBO and WBC.
According to a CNN report, the bout ended in spectacular fashion as both fighters, visibly exhausted, desperately tried to land their final punches.
Such was the closeness of the context that a return fight seems inevitable. And the calls are for it to be staged at Croke Park in Dublin where the context would be a potential climactic moment in Taylor's stories ring career.
